Sprint bouncing towers, Verizon steady - EVO 4G General

Maybe this should be in the Development forum - it asks for rather technical insight. I am using an HTC EVO 4G (not rooted or anything fancy - just as it came, except one temporary hack discussed later).
I am trying to figure out why the Sprint coverage in my area is just not up to par. I tried a little experiment - very unscientific, but it gave some interesting results.
First I downloaded a program called Antennas from the marketplace. It tracks which cell tower you are on based on the ID info being sent to your phone. Great little app, by the way.
Then, I drove around the area where I am having trouble -- only a couple of miles right in my town. The Antennas program showed my cell signal bouncing from tower to tower constantly. It never stayed on one tower more than a few seconds, and it seemed very unpredictable as to which tower would be next. Sometimes it would show me connected to a tower clear across town when there was a tower much closer, then it would bounce to the close tower for a short time, then off to another tower.
So, after my informal tower survey with Sprint coverage, I changed the PRL on the phone to use Verizon's towers. Then I drove around again, and got VERY different results. The signal stayed steady on one tower until I got closer to another one, then switched cleanly. Only once or twice did it bounce back and forth from tower to tower. For the most part it stayed with the tower that was closest to my location.
I am not sure where this gets me, but I would think Sprint could drastically improve both voice and data coverage if the phone stayed on one tower.
Any thoughts on what this might mean? Or, if the signal strength can be stabilized?

I wish I could help, but at least I can let you know you're not the only one. I only notice this at home.. and I live 3 blocks from a sprint store with a huge antennae on top. I would understand if I had a bad signal, but it even does it when I have 5 bars... and of course, it usually jumps to a tower that gives me 1 or 2 bars... and then 3 or 4 more towers before I get back to the tower that gives me 5 bars. Then it repeats. I haven't seen 6 bars at home, but I wonder if that would cause it to be happy and not jump to a different tower. I'm also curious if the new 2.x radio will change anything. I've been too lazy to update it and see..

How do you change radios? Are these software hacks for the radio ?

What is your db when its bouncing? Ec?

Wow same thing even though I have an antenna really close.
Are you rooted?
Swyped from my Evo 4G

Mine is bouncing between 3 towers within just a cpl of miles from me. Never stays on a single tower. Inside I get a horrid signal around -99 to -105...usually around -100 though. Outside I hit -85 but that's the best it gets until I hit one of the cities I'm between. It's disappointing to see those towers so close and have such a crap signal. I love VZW and their lower frequency but won't be leaving sprint anytime soon.

-100-115 is very very marginal signal. If you see that very often that could be why you are bouncing. -85 is pretty decent signal so there should be no reason to bounce then.

I believe he changed to the Verizon/Alltel prl.

i have a good signal and mine jumps between 3 towers right around the corner from me, i didnt know they were that close.
good app! thx for the heads up

Yeah...even when I'm in the -80 range outside it will bounce back up to -95 or so. 3 towers within just a few miles and its like a pinball machine. Bounces everywhere haha. Shouldn't have a -95 plus signal outside that close to 3 towers (based on the antennas app)

we need a widget to force lock evo to the best available tower at the moment... i can imagine this would result in saving precious battery since evo won't be constantly looking/jumping towers.

Is there a way to go in and lock onto a specific BSID or make a preferred selection? I have researched prl files a lot since getting this phone, but haven't seen a way to lock into a specific BSID. I am always locked on the SID of 4812, which is MEMPHIS. We just need to lock our strongest BSID location but I am clueless on how to do this, if we even can.

The software Antenna's i believe is not designed for CDMA so the results you get are sorta not valid
for those who see bouncing, make sure you update your PRL after you get your phone. sometimes, based on where you are when activating, the PRL may not load correctly. hope this helps

Yeah, def update your PRL. I looked on my phone today and it had a prl ending in 63, and when I updated it ended in 67.

I've been on 60667 since it's been out, and just modified it to try something out. The "antennas" app gives a rough idea of CDMA connections, but not as detailed as if you were using GSM. It still accurately verifies my SID, type of data connection, and BSID but that is all. If anyone happens to know if you can lock your BSID or any info on that I'd be interested.

I have 6 towers in a 1.9 mile radius of my home... I don't even want to see how much bouncing occurs... I got an Airave and wifi - done with the signal issues.

One thing to keep in mind is usually the device will be pinging at least 2 different towers just to maintain a connection should you go out side of the range of tower x then tower y will pick up. This prevents lots of call drops in moving situations.
Also if you are in range of a roaming tower I'm not sure how that equates but the device could be looking at that as well if your signal is < -zDB.
Not sure, just some food for thought.

Besides the fact that bouncing seems bad, is there any evidence that it actually does any harm?
Perhaps it only bounces because none of the towers give an acceptable signal?

Just a few notes in response to prior posts:
My signal tends to run between -90 and -100, so it is definitely weak. When I get into a stronger part of town I still get the bouncing effect. This morning it jumped from a tower giving -68 to -80 then back to -68, and another time -75 to -90, etc.
I realize the Antennas program might be off with CDMA tower locations, but it does accurately show ID #'s so I can see it switching back and forth.
Elsewhere in the forums are threads talking about Time Without Service (TWS) being a big battery drain. This is a problem for me, and I wonder if this is connected to the bouncing towers. Overnight I can get anywhere from 50% to 95% TWS on the battery use. And that is after trying to implement the CDMA Auto (PRL) fix found in another thread.
Believe me, if it wasn't for the good deal I get on Sprint's monthly service I would be gone in a heartbeat! I guess it's the ol' you get what you pay for. I loved the HTC Incredible on Verizon, but I just couldn't swallow the monthly charge.

Verizon Network Performance...

What are the forum's opinions on Verizon's network? Especially those of you who changed to Verizon from another network for the Incredible.
I'll be honest. The network has not been bad, I have service most places and 3g is decently reliable and fast. Not really digging that antenna indicator that makes up the bars on it's own, but performance was pretty good.
However, I didn't expect 'ok.' I expected 'The Network.' I expected moving from tmobile, the smallest carrier, and the n1, a phone with horrible antenna problems for alot of people, to get reception anywhere other people had reception. But in my area [suburb of Dallas TX] ATT seems to actually have more reliable coverage. In my house Tmo gets no reception [my house is a dead zone apparently.] ATT gets full reception. So in changing to verizon I checked their coverage map.... full 3g everywhere in my area. 1 bar in my house. 3g in my garage. Better than Tmo but ATT is 5 bars 3g!
And as far cities or major areas... never had a probl with Tmo there, always good HSPA. But leave a city and roll the dice.
Overall I rate Verizons network a 4 for North Texas Area. Tmo 3 Sprint 2 Att 5.
For Boston, my TMobile phones had much better call quality/clarity. I have not dropped any Verizon calls yet, but it is sometimes hard to understand what the other person is saying on the far side of the line.
On the other hand, the 3g speed and coverage has seemed good.
I have noticed the greater 3G coverage. I came from AT&T and this weekend I traveled across the country and spent some time in 6 different states, CA, IL, TX, NY, NJ, PA. Some were just driving through, others were airports. Never once did I notice a lack of 3G coverage. However most of the time I was at 1 or 2 bars, although that didn't seem to effect my experience.
It even worked in the plane at 30k feet, but only when I was above a major city. Gave me enough time to download an app. (yeah I know they don't want you to do that, I'm bad)
Coming from AT&T I do miss one thing, Data+Voice at the same time. More than a few times I was on a call with the hotel or car rental and they asked me for information I did not have handy. It was in my emails, but I couldn't access data to get them while on the phone. So I was put in a position where I had to anticipate what information I needed before a call and pull it up first. Another time I was talking to a friend about where we were going to meet, and I couldnt access Google Maps. It's kinda annoying.
I switched from T-mobile and while I'm gonna be missing my nexus once that 2.2 update comes out, my coverage is amazingly better, and my service overall wasn't that bad to begin with. Verizon has far surpassed my expectations.
Verizon user here who left Big Red, went to Big Orange, and then back to Verizon.
In my experience (here in central and western Pennsylvania), AT&T is hands down faster. This is simply the case with GSM as opposed to CDMA. However, 3G coverage with AT&T is spotty, whereas Verizon is awesome.
I have also noticed a misconception that # of bars is best indicator of performance. A better measuring tool is to check the following:
Menu > Settings > About Phone > Network
Take note of the Signal Strength. Somewhere around 50 dBm is almost excellent coverage while the closer you get to 100 dBm is borderline questionable coverage.
I am back with Verizon after less than a year with Sprint, and I am glad to be back. I had left VZW because of their crippled phones (reduced memory - disabled features - etc.), and not because of their service, which was fine.
I was quickly reminded that no matter how good a phone is, it's not worth a damn when paired with lousy service. Obviously YMMV, but where I live, near the edge of town but supposedly in a perfectly normal coverage area, Sprint is seriously lacking.
Average signal at my desk with Sprint was -95db or worse, and maybe as good as -92 if I went upstairs. Calls would drop fairly often, but even worse were the ones that *didn't* drop completely, and instead just went all flaky with audio cut-outs (with both phones I had on Sprint, the Touch Pro & the Hero). I was always running upstairs anytime an important call came in, just for the few db less signal loss, in the hopes that Sprint wouldn't ruin the call and make an ass out of me again (I can do that just fine on my own, thanks). Data throughput was also pretty inconsistent on Sprint. Sometimes it would work great while I was at some other location such as onsite with a client, but that just wasn't good enough. I need my phone to work where I live.
Anyways, back with Verizon things seem pretty steady for me. I get an average of -90db or better at my desk, sometimes as good as -85db, and if I go upstairs I have seen signals as good as -78db hold for a while. I have only had a single dropped call, and I saw no sign that it was a signal issue at the time. All of my calls have been clear, with no detected or reported audio cut-outs. Real-world data throughput is also much better for me than it was with Sprint. Web pages load consistently where they used to be sporadic, downloads don't stall anymore, and videos buffer just fine that I couldn't even touch on Sprint. No complaints about service here.
I wish Sprint all the best, but they won't be getting any more $$$ from me anytime soon. As for Verizon...well...what can I say except "Hey baby, thanks for taking me back! I missed you."

Att 5, lmao
Try this get speedtest from the market, have your friend get speedtest from the app store, whenever you have the chance post run the test 3 times simultaneously and see how bad att network is. att network is like a ford fiesta, nobody wants it, but some are forced to endure it.
my conclusion on vzw is i am ususlayy getting 1.5-1.75 Mbps down and 600-1000Kbps up all the time at different locations. My friends iphone has never hit more than 1.2 , usually its 400-800Kbps down and up 200-500Kbps
i know different areas have different speeds, but in my area and most areas i have been to, mostly west coast, these results seem to be the norm
VZW coverage has always been great for me. Everywhere I go I ubersexual great reception in voice and 3g. I work in the Nevada desert sometimes and had data coverage where I wouldn't have expected it. And voice coverage was nearly always there. Can't wait for LTE.

Once I exchanged my phone for another because of something unrelated to signal I have noticed a difference. Before my phone would stick on 1x but now sitting in the exactly the same spot I only get as low as Rev-A. So there was an obvious problem with the radio on my last Incredible.
I've seen a few places where ATT could get out and VZW can't. Usually on a dirt road in the middle of nowhere. Having said that VZW is always crystal clear where ATT is garbled. I drop a VZW call about every 6 months.
I don't know what the Incredible's deal is with bars for the signal indicator, hut its not accurate. With the MOTO Droid sitting side by side, the DI always have less bars but is you watch the actual dbm, its the same or slightly better. I given on using bars at all. I just check that I have signal. I've done a lot of travelling and I have not lost service yet. some of my travel is in rural Mississippi.

I had to go with a 4. VZW service is the best I've ever had, but coming from T-Mo, I got spoiled by the voice+data simultaneously. If that somehow became possible on CDMA networks, VZW would be perfect in my eyes.
I live 20 miles out in the suburbs in SC and I get 2 bars and 3G all day long. VZW has the coverage.
I came from AT&T to Verizon last month in NJ. It's one of the states where it's just blanketed in every cell service. Verizon is the best network I have ever seen. AT&T's network was unusable at times. Their data network was complete and utter garbage. I browse faster with Verizon on one bar than I ever did with AT&T with full bars. I'll never, ever go back.
I to am in NJ (NY Metro Area) Signal strength at home is a constant -71dbm, and at work a phenomenal -64dbm, had Sprint(my work),ATT(wifes work),TMobile (Son's current) all were "ok" but data by far is much faster with VZ, and I don't recall any dropped calls.
Super fast 3G outside...Tmobile's was MUCH slower. But seems like T-mobile signal in Atlanta could penetrate any building and the second I walk indoors with Verizon I am jumping around on 1x all the time. Cant get a 3G signal at work and spend 9 hours of my day there. T-mobile full bars of 3G goodness. 1 dropped call so far in 3 weeks so thats really good.
Verizon network is good here in Washington D.C. Metro area and surrounding areas. Ive only seen one dead zone while riding VRE train, its between stafford and quantico. Ive never had dropped calls or bad call quality. Only complaint i have is 3g speeds seem to be a lot slower in the city dunno if its maintenance or just too many people on the towers or w/e. Not even able to stream internet radio sometimes while in the city. speedtest.net app shows between 80kbps and 200kbps while in city. I get up to 4000kbps at my house outside the city in Fredericksburg.
Cycling from 3G to 1X
Data service will not lock into 3g but every few minutes jumps between 1X and 3g with attendant decrease and increase in data rates: 1x - 60 to 90 kbps down, 40 to 80 kbps up, 3g - 240 to 400 kbps down, 180 to 320 kbps up, all are average and sometimes much better on 3G during non peak periods. VZ reports no data problems at location and said to contact HTC.
Not a signal strength or reception problem and does not happen on two other phones sitting side by side with INC. INC: -87 to -89 db, Samsung Omnia II: -86 to -88 db, BB 8330: -87 to -89 db. All other phones have solid 3g signal and data rates all the time.
I really hesitate to exchange this phone because everything else appears to be working fine after doing the EVRC-B change to improve voice quality and I don't want to get another one with some other problem. Guess I'll wait as long as possible in the 30 day trial in hopes that either a fix is put out or a later batch of phones won't have the problem.
Re: Cycling from 3G to 1X
Replying to my own message: I now know why I am seeing this behavior. I got a free app "Real Signal" from the Market which displays the CDMA and EVDO signals in db separately. If this app is accurate my INC has a 10 to 20 db difference between the two with the CDMA -87 to -89 and the EVDO -95 to -118. So it looks like my INC has an antenna problem or a radio front end problem for the 1900 MHz band.
Also it seems that the change from EVRC to EVRC-B has not improved my voice quality as much as I thought as all day yesterday I had several calls that were muffled and dropping syllables. I do wish that HTC would get its act together as this is a great device otherwise.
I had iPhone 3G on AT&T in northern VA now with Incredible on Verizon I see huge upgrade in terms of speed and covarage. Its great!! also incredible is far better phone than iPhone.

Signal Problems: is it Sprint or the EVO?

I switched over from Verizon and I have had my EVO since the 4th of June. I like the phone, however I get very poor reception. At my house inside, I get 1 bar, sometimes it will be no bars or 2 bars. I used to get excellent reception in my house with Verizon (usually full bars). My wife is on T-Mobile and even she gets 3-4 bars (out of 5 bars) and never has dropped calls. I always get dropped calls.
I used to be able to ride in the elevator in my office and talk on the phone. Quality would drop and i would lose bars (down to 1 or 2) but I would almost never actually drop a call (this is on Verizon). Today, in two elevator rides on the phone, they both dropped.
Now my question is.... is this Sprint or is it the phone?
If it's the phone are there certain ROMs I should try that improve the reception?
Thanks!
You should try to do the little hack to get on verizon towers without being classified as roaming. Check it out, if its sprint then you will see once you try it.

Different radios might work. For the last 4 years I've been an AT&T customer. I understand that CDMA apparently isn't as good at signal building penetration compared to GSM, so that might be a limitation.
However, both Verizon and Sprint utilize CDMA, so I find it odd that someone with Verizon could have a better signal than Sprint, since I'm also told that (assuming your phone has the "roaming towers" option or whatever it's called enabled, and it is by default, at least on my phone) they use the same towers, so why on earth would there be a disparity?
I'm guessing it's the EVO, or something to do with its casing, because some places I get excellent reception indoors, and others, like Sam's Club, is a complete dead zone except for the front third of the store closest to the exit.
That being said, my wifi reception (or at least indicator) totally blows. I hope a firmware update address that and the 30 fps cap, as well as reception (if it's the phone).
Try the *techknowfile's* - Hack the HTC EVO - 3G w/o Sprint EVDO coverage!
It worked for me. From having no bars went to full at home because of Sprint coverage. And the EVO does not have the option of roaming, just the automatic roaming and never worked for me.
About Verizon and Sprint they are both CDMA but they have their own towers. Is not the phone. And at Walmart almost every phone loose signal. I have friends w all carriers and they all get poor signal.

Obtain your MSL (aka Master Subsidy Lock / Password. SIX DIGIT NUMBER)
Dial ##775#, a password prompt should appear. Enter your MSL into this box->hit OK->tap on the "Update PRL" button. Make sure "All Folders" and "Type: prl files" are selected. You should see the downloaded PRL (00001.prl) on the list; Select the PRL->Press Menu->Commit.
Search the forum for Hack the HTC EVO - 3G w/o Sprint EVDO coverage! under "EVO 4G Android Development"
the tutorial is on the first post by Techknowfile.
try a different radio, or maybe its just the area u are in? on ATT, my friend has an iphone, and i had the fuze, and he always got signals where i didnt, so it could be the phone...
You can't go by bars on CDMA... You can have ZERO bars and still be able to make crystal clear calls and send and receive data on CDMA whereas on GSM you hit 3 bars and your calls start cutting out.
Anyway, I've noticed that the EVO is really crappy with data speeds - but voice quality it is bar none the highest quality cell phone I have ever used.
Well, if the Evo simply has poor reception the Verizon hack shouldn't make a difference.
I like you have poor service in my home, always have. I got an Airave to solve that problem, it works well so long as I also am connected to Wifi otherwise it tends to hop between 1 bar of 3G and full bars of 1xRTT.
I tried the Verizon PRL hack. The signal was a little stronger, inline with what my roommates on Verizon got, but it wouldn't connect to the Airave at all. Did seem to have a hard time maintaining a 3G connection. I wasn't losing the signal, it just seemed to drop the data connection, but I still had a voice connection. Because of that and the airave issue I switched back.
The funny thing is, the EVO has better signal reception than my TP2... it just has crappy data speeds.
really? i get amazing data speeds on 3g, also i found out today that wifi speeds and signals are being fixed via software update from HTC, just got an e-mail from there. something like 700 down and 700 or so up.

If it helps, everybody in NYC knows that Verizon is the best in signal. You can get signal with them where ATT and Sprint can't. ATT has the worst signal in the city of the 3 of them. So it might be the carrier. I don't know if this is true somewhere else.

I have a simular issue, so I called sprint today and the tech found that the tower nearest me (about 1 mile away) was "out" so that was my problem so he generated a ticket to fix the tower. The funny thing is that he indicated that in general thier system can not tell them when a tower is out, customers generally call and indicate a service issue then they can remotely check the towers in question for issues . Man that is not the best way to check towers . Oh well the tower I need should be fixed in about 24 hours based on the tech I talked to.......he also said good thing I called Man they have a nutty system
Verizon's method of checking towers isn't much better if all they have is one guy walking around asking "can you hear me now?"

Sent via this here phone thingy on the interweb.
i've found it to be the opposite in my city. verizon is terrible and sprint is awesome. maybe in your area, sprint just isn't as good as verizon? don't think it's the evo.
This is easy to check.
Go to a different area and see if the signal gets better.
My own evo is better than my old TP2, much better reception (I don't roam at work, on the basement floor, whereas TP2 used to constantly) and 2-2.2 down / 0.6 up Mbps.

I just switched from a TP2 to the Evo and I found things to be quite the opposite. Constantly 1 - 2 bars less of service with the evo dropping to 'no service' where the TP2 at least had 1 or 2 bars. After many years with HTC products, Fuze, Tilt2 on ATT and the TP2 and EVO with Sprint I have found that its really hit or miss with their products. Some phones of even the same make and model are just better then others. The first Fuze I got had horrible horrible service. Went to the ATT store and they agreed, warranty replacement phone worked beautiful. Now with that said the EVO does seem to have consistently faster data speeds then the TP2 did. Between 600 - 900 with the TP2 and up wards of 1480 on a test I did yesterday with the evo. Still no where near the 2000 - 2500 the ATT network provided but they ticked me off with their two week tower outage in this area... what good is speed if the phone doesn't work?

Sprint's 4g connection not stable...

Im in the northern chicago area and I'm able to connect to 4g but the connection is slow and unstable...(even with 4 bars). Ive extended the idle time using ##data# but still I have the same issues??? Anybody with a solid connection care to share their ##data# settings? Im thinking the issue might in the settings......

I'm in Seattle and see similar 4G behavior. Usually 2 bars or so and not great performance (marginally better than 3G). I'd be interested to see if this can be improved by tweaking the settings also.
the 4G antenna in the EVO is half the size of the USB one, I don't even get signal at my house on my EVO, yet I get 1.5MBs on my USB stick. Size matters.
Idk about 4G but i just moved into a new house and i have TERRRIBLE reception no matter where i am. If im not outside, it sucks. Its funny though, as soon as i step out the door, 5-6 bars. Im keeping the phone in hopes that as soon as they get 4G around here (Elmont, NY... Long Island), things will change. =\
sprints 4g is in a horrible part of the spectrum. it's frequency is too high to pass through anything
This thread does not belong here. Take this drivel to the appropriate subforum.
unless you are a running a stock rom with the latest updates, i don't think you can make any of these complaints that you all are unless 4g isn't fully up and running in your city. My girlfriend just got the white evo and we installed the latest updates and she gets a very good 4g signal, i have the black evo running fresh 0.5.3 and i get a pretty good signal myself. Not to mention we live in mpls and 4g isn't even officially here yet. A lot of these problems people are having are user errors, flashing things with no knowledge of what they are doing. I would say go back to stock do to ota update with the new radio and wimax enhancements then tell me what type of 4g coverage you are getting. otherwise you are just trusting the chef that everything is set up right which i would take with a grain of salt because non of them seem to understand exactly how the wimax radio works as of yet. Proof of this is all the problems people are having after trying numerous roms

That's not very encouraging, I am very disappointed by Sprint's 3g speeds. I have yet to see over 1mbs, and over the 4th of July weekended saw .2-.7 mbs. Yes, .2 as in 192kbs. This was in Miami.

I started this thread with the intentions of looking into the settings of the wimax ##data# menu....not too rant about the service. I believe with the good signal I'm getting and the fact that I do connect shows that there's an issue with either the roms were flashing or the setting mentioned above. Anybody care to post their settings?

Changing the wimax idle sleep time from 10 secs to 300 secs could help. My 4G stays on pretty much constantly now instead of switching back and forth between 4G and 3G. You would need your MSL to edit the settings though.
I have similar issues in the chicago land area as well. Very frustrating. I am using a stock rooted rom, but I am using an older OTA update. When I'm outside I always have a strong 4G signal. However, as soon as I go in doors I either loose the signal or have a very weak one. Before you say anything about updating, my GF's EVO is completely stock with the newest OTA update and her 4G behaves very similarly. I actually pick up a better signal at times. It just sucks because if the signal was just a LITTLE bit stronger I would be really happy.
Thats just due to the spectrum used for wimax is at such a high frequency that it does not penetrate walls very well. I'm not sure how sprint will try to remedy this problem, I'm not sure but I get strong signals at my work office and thats inside a building. At home I can get 4G if I am outside once inside I cant seem to get it at all.
What's "##data#" ? I would search it but haven't quite figured it out yet on the app. Google didn't help either (surprisingly).

jr - I am in Gold Coast and recently noticed the 4G signal was junk. It used ot be great inside my 13th floor apartment. I went to the sprint store and they said one of the towers was being serviced (they called a tech. and he said this while I was there). They said end of this week it would be fixed. I was going to give them another week or so and see what the deal is then.
IMO it kind of defeats the purpose of having 4G then. 90% of the time that I want to surf the internet or use 4G I'm indoors, and I would imagine that goes for pretty much everybody. I know this isn't a problem for everybody so it seems, but I think for a lot of people it is.
interesting you say 4 bars of 4g. when i look at my phone i can get up to 6 vertical bars for 3g's signal strength, but with 4g on, and outside i can get 3 "bars" more like "upper wifi arcs" above the 4g signal. and inside my 4g doesn't even register anything, it just shows 4g with no arcs...
however my technique is to put the phone right next to the window and run my micro usb cable from there to my computer. and i then get great data connection...
still experimenting, (had the phone for less than a week) but i think it might work better to go to menu/settings/wirless&networks/ and uncheck mobile network so the phone doesn't use the 3g for data connection when 4g isn't there...
thus if the 4g signal is low, it doesn't drop it to grab the higher signal 3g...
lastly. i'm heading to the store to try to pick up a 2 buck plastic soap dish with a suction cup for the "high tech holding station" on my window. that and a 10 foot micro usb cable i think that will help even more...
best of luck.
I have figured out where in my neighborhood I can get a 4G signal (and I too keep my phone near the window when I want to use it at home). However since the OTA, I noticed that if my 4G signal drops it won't come back unless I toggle the 4G radio. It will just sit in "scanning" and use 3G.
Anyone else noticing this problem?
I would assume that one of the settings/timers need to be tweaked, but I have no idea what my those values were before the OTA.

4G has nothing to do with 3G. Clearwire maintains the 4G network and Ericsson maintains the 3G/1X network do if your 3G is bad now, it won't be any different when 4G launches unless Ericsson improves the situation.
If I'd got this device predominantly for 4G...Id've returned it in day one...(IN Chicago also). In fact wouldn't have bought it going in knowing what I knew about the spottiness of tapping into 4G frequency wirelessly.
that makes absolutely no sense.
per your words, 4G has nothing to do with 3G as in Clearwire has nothing to do with Ericsson so what would it matter if Ericsson decided to step its game up if Clearwire is the 4G company?
4G is on a whole different frequency not to mention a whole different tower technology and tower location possibly so there's definetly a good chance that I can maintain a great 4G signal once it arrives in my area compared to the terrible 3G coverage I get.
well see what happens... my luck they will never put 4G by me lol.

[Rant!] I can't take it anymore...[ 4g data disconnects ]

Literally every time I try to watch a video in HD on youtube, my connection goes to ****.
I can't download huge files wthout a download manager because they will fail. And where the download manager saves me is by continuing the transfer when I bring the network back up.
I can't play ps online or xbl because the traffic kills my connection.
The ONLY thing its good for is browsing webpages.. that's it!
I live close to a 4g tower cause when I'm peaking, I get 10-13mbps+ its just when tethering or not, the connection times out..
This phone [SAMUNG] has terrible implementation regarding its Wimax radio. I soo wish I could pull out the HTC hardware and stick it in, cause it never timed out like this. Nor did it cause data disconnect upon taking a call while on 4g and tethering..
PLEASE can someone look into why this is happening?
I know I can't be the only one..

I have a similar situation with/without the fix. It seems my signal strength (or bars) have improved, whether perceived or real, but reliability is crappy. I basically hold very very still when trying to download a podcast. The highest I've ever gotten is around 6mbits/sec, but usually, if it stays connected, I'll avg about 1-2.
I honestly think that this may have more to do with the wimax technology and towers. I have a Clear bundle ( usb and home) and I live in full 5 bar and 10 bar coverage, and my speeds fluctuate greatly. Now on my phone I always get a solid connection and hardly any fluction albet slower speeds than the other hardware at times. I think the tech and the hardware have more margin of productivity and constant throughput error than sprint or clear wants us to know until they updrage to true wimax 4g. Just my thoughts, maybe your radio is one that doesn't like the tower close to your house.
Call and ask about tower issues, or maybe try a replacement phone, hopefully this is helpful.

Thanks for thr input guys, my problem is not my thuroughput its actually quite amazing. And rarely on the lowside. Usually 8.5ish most times.
But rather my problem has to do with the Load put on the radio, when downloading a file. Just like when I had problems with cable modems, it would crap out.
I actually did those wimax settings even tho I have te best signal, so great that I'm full bars inside my home at all times [unless I'm covering the radio in slide out mode]
Sigh.. just sucks not to be able to take advantage of my great speeds. Cause I really need to view the 1080p videos on youtube, looking at samples of the Canon 550d/t2I I am getting

When tethering, I keep my phone stationary in a stand (an izel). That has made my connection extremely reliable and I can stream entire movies without any problems.

I get it with or without the fix. At home and I am less than 1/2 mile from a verified 4G tower and even though I can at times get Speedtest results over 8Mbit there isn't anything that is constant about the connection. 4G is unusable most of the time because the connection will drop about once a minute which then ticks off the phone and this is in an area with a high signal coverage. I also have an Overdrive and it doesn't seem to suffer from the same issues or if it does it doesn't do it as bad.
I'm wondering if it's related to individual tower's broadcasting equipment. I've been places where 4G will stay connected all day regardless of what I'm doing active or not. But the office where I'm working now it constantly connects and disconnects (load or no load). I've tried the fix in the other post, and it hasn't helped here.
Maybe Sprint's Network Vision program will fix this problem.
I just contacted Sprint about the same issue. I'm in Miami, and if this issue persists I'm going to cancel the line. It is annoying as hell. I wonder if it happens with other 4G phones?
Alright thanks guys we have good reports here.
My htc evo didn't do this, I stayed on 4g downloading all day for 14hrs straight at times. Only problem I had regarding 4g on the evo was trying to get the 4g to stay on, while I turned on the hotspot. Once I got it. It was golden.
The epic always have the problem with maintaining the connection. I can say my location doesn't make a difference for me, regarding this issue. But also how would I find out how close I live to a 4g tower? For the speeds I get, it has to be on top of my roof lol.
What is the Sprint Network Vision program? I'm about to google it

I also had reliability issues and discovered that my office computer was at fault - some kind of RF interference. It's rock-solid now.
well no wonder i have such good throughput and great signal. Used the WiMax tower locator.
The nearest tower to your location is 0.82 miles away, bearing 59 degrees>
i am reading your post, I am trying different locations away from my pc to see if this this helps. thanks for the input. I would like to mention my room mate has at least 15 RC cars. Gas and electric ones, running off 900mhz or 2.4ghz.
he is always on them noisy ass things lol. But this happens even when he isnt on them, and like I mentioned before, the HTC didnt do this--BUT thats not to say this isnt the case with the epic. Two different machines. and hardware for sure.. Samsung barely got the 3g modem right after the release of DI18 lol, **** what makes you think they can handle a wimax radio
At this time there is currently a 4g outtage nationwide on sprints network... I do tech for them and it started sometime around the 22nd or so had a few days off befre that so I can't give you an exact time... as of 11 mountain time on 2/1/11 there was no fix yet...

LOL - about 6-7 down here.
I'm in Ft. Lauderdale, and my experience has been that in areas with solid 4g, the connection will drop the moment the signal from a tower *besides* the one that gave you your IP address hits 3 bars.
Example: southbound 95, initial connection between Sunrise & Broward Blvd, gridlock. Watch the signal strength peg at 3 bars near Broward blvd, slowly drift to 2, then 1 by Davie rd... then go back up to 2, and drop when you're close enough to spit on the tower next to 95 at the river. If you toggle 4g off & on right then, it'll reconnect almost instantly with 3 bars. It wreaks havoc on Pandora, to the point of being unusable.

Slacker radio is the app I use, and keeping the Epic on 3G works best for the same reasons the previous poster states. There I get good performance almost everywhere in my town. If I'm using a constant streaming app though, I will hit patches of trouble especially if it's a fast CD-quality stream.

I work and go to school full time so 90% of the time I'm inside of a building. I'm finding that even seated in front of a huge window I have no data signal it just says "emergency calls only" and the wifi is so terribly weak I can't even connect to the campus wifi. Anything I can do to improve this before I consider other options?

T-Mobile will NEVER be good at building penetration with their current network; it's the high frequencies they use and the lack of close-together towers.
WiFi seems to be hit or miss for people. I have zero issues with WiFi on my phone, but lots of people complain the NS is weak. You might consider a swap if you're still in the remorse period. Other than that, unless you get closer to the WiFi, there's nothing you can (currently) do to the phone that will boost the reception, but software updates might address that (new modem software, etc).
that is the nature of AWS 1700+2100 (t-mobile) signal
some areas are really good, some areas are horrible
i myself i'm victim of that, no much you can do about it, other than to report weak signal areas, so that they can put up more towers to cover the black spots (http://www.youtube.com/watch?v=kAG39jKi0lI)
as for WiFi signal... i don't seem to have that trouble
i can connect to WiFi G and N just fine, fast and strong 3 bars, or 4 bars, but never max

I find that I am having the same problem.
The understand network signal issue that "AllGamer" and "distortedloop" mention. But I am came to the Nexus S from a G2. I wanted a purely Google phone and paid for the Nexus S. In the same buildings (Work & School), My G2 would report a stronger WIFI signal.
Any reason for this noted discrepancy? I'm not complaining, just trying to understand and find out if there is a solution.
I think I'm still in my 14 day period, so I may swap it out. But it feels like I've been setting up phone preferences and reinstalling programs for months. I've been through several G2s because of that darn hinge and now another Nexus-S.
Please somebody--- say there's a fix.
I get 2 bars of wifi only 10 feet from my home router even. Im out of my grace period but I have the 10$ a month best buy insurance, could that be used? Sadly I'm looking at the g2 and hd7, some form of reliable data is a must for me.

I live in a terrible service area. With my Sprint phone I had to actually go outside to be able to make and receive calls and I live in the Northwest. Its f***ing wet here. On Tmobile I get great service...on my couch only. Its better than having to go outside, and I don't mind it that much to be honest. I just leave my phone on my couch while I'm at home and all is well. As for WiFi, I've never had any issues though I've read about all the people complaining. My wife and I both have great WiFi reception or at the very worst, reception on par with every other phone I've owned. She goes to class inside a concrete building from the 70s and gets fine WiFi and no one on any carrier gets any real cell reception in those buildings.
I don't have experience with any other carrier, so I have no basis for comparison, but I've never found T-Mobile to be particularly bad inside buildings in general. Some are just really bad. I suspect it has a lot to do with the design and materials of the building. I've never had an experience of having such bad coverage by a window, though. Maybe you're only in range of one tower, and the window you're standing at is just on the opposite side of the building from that tower? I dunno.
Thanks for all the feedback fellas. I'm going to see if the best buy insurance will cover a phone swap.

It most likely won't. Your best bet would be an exchange if you're within the 30 days or selling the nexus and buying a different phone off contract.

T-Mobile's overall service is definitely location-dependent.
I live in the suburbs of Los Angeles. My house is single story, wood frame & 1/2" stucco construction built in the 50s. It's in the "hills", but in direct line of sight of two different towers. One's maybe 3/4 miles, the other just over a mile.
Until a couple of months ago, I could not get any signal in my house, on either voice or data. They did something in the fall and I started getting voice and EDGE, and occasionally I'll get a single bar of 3G in some rooms of the house.
AT&T and Verizon, 5 bars inside my house, but in fairness to T-Mobile, in the early days of the iPhone, I remember having lots of dead spots inside the house with the iPhone.

Crazy. I never had a smartphone when I lived in Rochester (MN), so I know nothing about 3G there, but I never had problems with voice calls unless I was in the subway or I buried myself in the core of one of Mayo Clinic's monstrous stone buildings. In Saint Cloud the only place I can recall getting no signal was in the middle of the cinder block labyrinth known as our student union building. In Portland, I get reception pretty much everywhere, though 3G coverage just doesn't exist still in sizable patches outside the city's core.
But yeah, I imagine it's like that with pretty much any carrier; some places, coverage just blows.
I've decided that I am willing to give up my nexus to get service through another carrier with better service in my area. Does anyone have experience with at&t? Does their band allow for better reception in buildings?

Yes if you live in an 850mHz area for ATT then building penetration is spectacular. But It's not totally common.
Also I read an ATT version of the nexus s is confirmed now. So that's an option.
I concur with RogerPodacter on AT&T. Their 1900 mhz signal isn't much better at building penetration than T-Mobiles 1700/2100 AWS, but 850 should be. I don't think a lot of areas are actually 850 yet.
If coverage and building penetration are your main concerns, I really feel Verizon is the way to go. Everywhere I hang out that I don't get a signal on either my T-Mo or my AT&T phone, the folks with Verizon are getting good strong coverage. I live and work in the suburbs and surrounding areas of Los Angeles; since cell service is very much dependent on the area you live in with all the companies, your experience may be much different.
Along those lines, I was at Lake Mohave (Bullhead, AZ area) recently, and neither my AT&T i9000, iPhone 4, or T-Mobile Nexus One could get a signal at all for voice or data, but the guys with old original model iPhones were pulling in a signal. Go figure.
My Own Fustration
Hmm...my problem is that 50% of the time when I am on the subway and the signal drops off, when I arrive at the next station, it remains off. There seems to be some kind of glitch (either in the actual OS or else something caused by something I have running in the background) whereby the phone antenna just turns "off", so to speak, and the only way to fix it is to restart the phone.

wow! i'm actually surprised there are less 850 coverage than 1900 areas (according to that map)
on a related note.
wish more Cell phone carriers had this feature

using google map, to check live coverage, and you can report weak spots, so they can build a new tower to cover the weak spots
