A cross-country trip, the Froyo Radio and what it might mean to you!

So I just recently took a trip from northern California to Tennessee and had some interesting results with the Froyo radio. For reference I own the ATT-version Nexus One and have data roaming enabled.
When I used the phone before Froyo radio I had many problems with the 3G switching to Edge and back when needed which caused random data dropouts. Even turning the phone off and back wouldn't force the phone to switch connections to Edge when needed which would make me very frustrated in times of need.
On my trip I found something very interesting, not only did 3G and Edge switch almost perfectly, but Edge performed MUCH faster than before. While it isn't as important now in a world of 3G coverage, when I was on the "edge" of civilization I still got surfing speeds that were not far behind that of 3G speeds. My browsing, and most importantly Google Maps usage rarely suffered a performance hit despite where I was or what type of connection was available to my phone.
There was a difference between performance; 3G would act like Comcast and Edge would be a little behind, but in terms of actually surfing the Internet the extra 2-5 seconds it took to load up a desktop webpage didn't make a difference.
Technically the bandwidth speeds were much different. 3G performed from 1 to a max of 2 megabits down and .3-1 megabits up, while Edge showed speeds of 300-500 kbps down and 100-200 up.
One thing I did notice throughout the trip is the Nexus One's signal meter did not report correctly, there were times where it showed no signal and I had super fast connection, and also times when it would show full or near-full bars and there was no connection.
Hope someone finds this info useful!!! I'm very happy with the coverage my Nexus One gets with the Froyo radio now!

I have always found that my nexus holds calls and has fast data showing zero bars. One reason I've always loved the nexus

Just a point of clarification, EDGE has a maximum theoretical bandwidth of 473.6 kbits/s for 8 timeslots.
In real world conditions EDGE should have throughput of 236.8kbit/s with 4 timeslots(which is what most carriers employ).

Wonder if there's and app/mod to replace the signal bar with the actual signal #s?

Hey Sellitus, what else did you find working/not working on that trip?
I am considering a longer drive (SF to NY) and want to know about battery life, apps that were really handy, and which weren't.

hey that would be nice. just like how cyanogen puts the battery percentage, it would be nice to have the dBm level of signal overtop of the signal meter.

The dBm and signal bar IMO opinion are rather pointless in regards to data. Having a very poor 3G signal will always be faster than a full GPRS signal.

Also, a signal meter in terms of DB would jump around quite a bit...

Well for ATT I hit data roaming quite a few times, and although it worked on edge pretty quickly during those times it would randomly drop when the R was showing randomly. I think what happened a lot on the trip is when I was out in the middle of nowhere bouncing between towers would cause random dropouts, but they were usually no more than a few seconds.
I don't remember which apps specifically though a few also did not like the trip, but most would hang and resume in a few seconds after data was reconnected even if the signal strength showed it was connected the entire time with signal. Sometimes Google Maps hung, though it was rare and I noticed it more because I used it near constantly on the trip.
If I were to give advice to anyone looking at a cross country trip, buy a map or get offline GPS maps to help. We bought a map and it proved valuable at times, though we rarely needed it.

I wonder if the "enable data while roaming" setting had anything to do with that. Maybe an internal bug.

I don't know how a number jumping around would be any different than a graphical signal meter jumping around. The iPhone has had this hack for a long time where you can replace the signal meter with the dBm reading. Though I've never owned the iPhone, but seen it on friend's iPhone before.
I know I'm often going into the android settings to look at my dBm reading, didn't jump around too much for me to see.

I've been having some reception issue lately with AT&T around my hometown (usually its quite good),so I did some googling, and found plenty of info on radio signal, and how to interpret -dBm, but I'm still baffled by the ASU. I really couldn't find much, just some random post on a random forum that left me with some questions:
In a 3G network your cell phone tries to open three channels to three radios so they can locate you and hand you off properly.
Those three channels make up you ACTIVE SET.
ASU is ACTIVE SET UPDATES or the rate at which your phone is able to update its location to the towers/radios.
This rate is affected by signal strength, load, and probably a lot of other factors that I haven't puzzled out yet.

Can anyone shed some more light on this? Usually at home I have 2 bars of HSDPA, somehwere in the -90s dBm, and anywhere from 4-8 asu.

signal strength

I live in lakewood, CA and the coverage map of T-mo says my place is Excellent. However, the signal strength is -82dbm on a desk near window. Today, I was driving to Fullerton. Every time I stopped at a red light, i checked the signal strength and it was at most -78dbm.
I found some posts of nexus one owners saying the signal strength is around -57 to -70 dbm when not holding.
does G2 have a weak receiver or is it just mine?

I wish I had signal strength as good as yours. I've never seen mine go above -90dBm!

I think its gotta be yours. I live in sammamish (washington state) and at one time I got to -50. I probably average -75.

I've gotten to -59 before and quickly decided to do a speed test. Using the speed test app, I get crazy numbers, I did a web based speed test and I got speeds (don't remember) but on a scale it said I was much faster than Sprints 4G network. Loving it.

What the... I'm at -89dBm with a full five bars. This is my second g2 and the first one was the same.
Sent from my T-Mobile G2 using XDA App

Same.. -85 dbm full five bars.. -113 dbm at 1-2 bars.

From my very unscientific experiments
I fired up my G1 tonight and installed the Mobile Signal Widget (handy widget, free on the market).
G1:
Sitting on my desk or being held in my hand, the signal reads -99 on UMTS. Very solid reading.
G2:
Signal reads -91 to -93 on HSDPA, then occasionally 'drops' to UMTS. Signal tends to show around -93 to -99.
These readings fly out the door when I pick it up and hold it like I did the G1. Within seconds, the signal drops to -101, shows no signal, then drops to either EDGE, or at an extreme, down to GPRS then goes back to EDGE, usually leveling out from -95 to -101.
Putting it down almost instantly sees the signal strength go back up to -97 and reestablish the UMTS or HSDPA connection.
I don't have the internal pictures or design plans for the phone, but it almost seems like HTC did the Apple iPhone 4 antenna treatment to the Vision/G2 and is using the casing as part of the antenna.
EDIT: ...Or put it in a bad place. I noticed that the signal drops mainly when the lower left hand of the phone is held/covered. Holding it by just the sides and making sure the bottom of the phone (area that has the trackpad) is not covered or being touched causes a much smaller drop in signal. Holding it by the top corners results in next to no signal drop.
Allegedly, TMo is having nation wide issues with the HSDPA side of the network according to the report of someone in the TMo forums (claims to have been told this by a CS rep, so take it with a grain of salt).
So while I don't think the G2 has a worse receiver, it does appear to suffer from bad antenna placement, which can look like a bad receiver. This may or may not be an issue for someone as YMMV depending on usage patterns, bluetooth headset usage, and so on.
As for the main status bar indicator, don't be fooled. TMo tweaked the signal display to show only H, E and G. Install that widget and watch it, I bet your phone switches between HSDPA and UMTS a lot, and the main display never changes from H.
I call this a bit of weasel marketing. They make this big deal about the new network and speeds and their flagship phone supporting it, but configure it so that it only reports the HSDPA side of the network when it's connected at anything faster than EDGE. Makes me wish for a way to track over time just how much time it spends using the UMTS protocol vs HSDPA.
I hate to say it, but returning this phone is looking like a better idea more and more...

You're retarded. HSPDA is 3G.

Fine, if you want to split hairs, I've corrected my post to reflect the correct terminology (UMTS vs 3G).
It doesn't change the fact that the Froyo install has been modified
It doesn't change the fact that it's verifiable with the free utilities on the market
I can't think of a single reason that the '3G' indicator in the OS would be removed except to 'hide' the fact that the phone isn't always using the HDSPA protocol, which is being bandied about by TMo marketing as one of the reasons to buy a G2. I don't expect a phone to have a rock solid connection 100% of the time, it's next to impossible. But I also don't expect a device to have been modified in a way that is misleading and doesn't show the actual protocol the phone is using.
My post was to add my findings about the subject of the phone having a poorer receiver than earlier phones, such as the G1 and the N1, and along the way I found something I thought was interesting enough to add to the post. Pardon me for not being specific enough at 3 in the bleeding morning.
Next time, try responding without the personal attack or apparently not even trying to reproduce what I have found to see if I'm making things up, OK?

G2 signal attenuation - any better?

I briefly had a G2 and quickly returned it to T-Mo and stayed with Verizon due to the signal attenuation issues I had. Additionally, I saw numerous posts about this on AF, XDA, T-Mo Forums and a few other places I cannot remember. My question is, have the software updates that have been pushed through helped this problem any? I really liked this phone, aside from the signal problems and now with it being free through the 20th at T-Mo, I would like to give it another shot, but not if I am going to have more problems.
For those who are wondering what I am talking about, the G2 issues I (and many others) had were similar to the problems iPhone 4 users had where the signal dropped down to very low or nothing by simply holding the phone. I could sit at my desk and watch it go from an H with full bars, then drop to E, to no service, then it would gradually return when I placed it back on my desk.
Additionally, the reason I made a post about this is that the forum topics about this seem to just have stopped, nobody really seems to be screaming "it's fixed!!!" So just trying to get some input as to whether it really is fixed.
Thanks for your input!

ive noticed this as well. It usually happens when I surf the web. No idea? It is annoying but it won't cause me to send it back. I love it too much compared to all the others i've gone through. I'm sure they will isolate the problem and it will get better. (here's hoping)

Never had any places on the phone that I touch where signal will just drop, though out here in the middle of practically nowhere my signal will randomly drop sometimes regardless of what I'm doing with the phone.

I think I suffer from this as well. It constantly drops my data, especially at my house. If I set it on my desk with mobile hotspot it works great, and I'm not touching it so I may have issues with that

I've yet to have this happen. Constant h in my status bar and signal is strong.
Probably a defect phone?
Sent from my Pear phone.

It happens. It happens with every phone, including the G2. It just depends on where the antenna is and how it's held. You can play around with attenuation by enabling dBm signal strength in CM.
To enable it, go to Settings > CyanogenMod Settings > User interface > Status bar > Check Show dBm.
dBm is measured in negative numbers. A higher (less negative) number indicates higher signal strength.
-80dBm is stronger than -100dBm for example.

This is actually a non-issue.
Explanation:
The phone actually picks up signal BETTER than other phones... especially when the signal is weak. The effect that you are seeing is actually the reception returning to a *normal* level when you happen to be holding it in some particular way.
I have two phones; an HTC DREAM and an HTC VISION. Sitting on my desk at work, the DREAM will show 0-1 bars, but connected, the VISION will show 2-3 bars. Holding both in my hand, the DREAM will continue to show 0-1 bars, the VISION will drop to 0-1 bars and both will read the same dBm. Same signal when held, the VISION is just more sensitive (i.e. sensitive in terms of able to hang on to a weaker signal, not sensitive in terms of flakiness).
In contrast to apple junk, the apple junk actually has the antenna wrapped around the outside of the phone. When you hold it in your hand and the signal drops, it isn't suffering from attenuation, its being GROUNDED OUT.

Whatever the cause is, the phone was unusable when I held it in my hand normally. The only semi-fix was to hold the phone at the top near the earpiece, which was uncomfortable...or never touch it.

Seems like you just have a poor signal or faulty phone to begin with. I don't have that issue at all. In fact this phone seems to hold a data connection in weak areas better than my previous android phone did. If yours was that bad then there was something horribly wrong that warrants replacement.
You may also try CM7, it seems to keep a signal even better than my current ROM does. Not sure why, maybe it's just a placebo effect.

Humm, no issues with Wifi, H or G3 dropping, Bell network though, BUT when I switch from H/ G3 to wifi, if I am on bluetooth, it gets all garbled and I have to hangup call. I would think a location issue or some form of interference you guys are having.

Nah, I'm positive that the sentiment is that the radio hardware does suck and there are definite attenuation challenges. I've now verified this through a myriad of different Desire Z's here.
At my work desk I get HSPA and HSPA+ speeds at times. However holding it drops it down so there are 0 bars and it stays on HSPA, drops to 3G with no bars, back up to HSPA, etc... lots of unnecessary band switching whereas other handsets will not do this. They'll get a lower signal/dB all together though. And their attenuation is a lot less.
If you hold the phone upright the reception is much better. Drop it down and hold it in landscape mode and there is an immediate drop and sometimes it begins switching bands depending on the service area you're in. It can be quite annoying being right on the cusp because that's a huge battery killer.
I really wish there was at least some modest software fixes to accommodate for this flaw. I know that much can't be done hardware wise at this point but I think some improvements should be attainable through updates and optimizations. Hears to hoping because I love my Desire Z!!

I agree. I experience this the most when I browse the web since I usually browse with the keyboard open.

There is a SIGNIFICANT amount of drop in Wi-Fi signal strenght whem the keyboard is open and your hand is covering the left side (top for portrait). However when the keyboard is closed and you cover the TOP again the signal drop is maybe by 1 bar....
As far as 3G/4G to EDGR drops are concerned.... that can be taken care of... if you go into radio diagnostics (*#*4636#*#* > Phone information) and selecting WCDMA ONLY...... this will prevent phone going into EDGE if minor fluctuations occur in the cell signal. Mind you, this option is only useful if you are in a GOOD 3G/HSPA+ coverage area....

Just remember to change it back to allowing Edge if you are going to travel outside the 3G/HSPA area.

I have noticed this since day one. It was very obvious at weak signal locations such as were I work. Inside a steel building with 20 machines running on 480 volts. I have enabled 180 degree rotation in CM settings and have used it this way so much that I have no doubt that the signal is reduced when the phone is held the "normal" way, in either hand. If I hold it upside down, trackpade at top, then it is fine.... also if the H signal is strong, more than 2 bars.. then it doesn't matter how you hold it.
I have compared this to my G1, that I still own. And the problem is that the G2 seems to have trouble switching from weak H to weak E and I can replicate a loss of signal everytime. I mean that an"x" Is displayed over the signal strength meter. And I can not make calls. This never happened on the G1. I have even disabled the ability to use H and it solved the problem. So then I took the htclib_ril.so from the G1 and used it in the G2. This didn't seem to change much.... So I believe that it IS a problem with the radio, or a problem in the librilswitch.so that does not get referenced in the G1 build.prop. But is in the G2...
If anyone knows how to make adjustments to when the phone switches from H to 3G to G to E I would really like to know. I think it could be the solution we need....

When I check my phone it always say HSPA and never HSPA+ whats up when will I know if I'm on 4G I'm in a 4G market Philly!!

I received my G2 yesterday, and it is a lot better at handling a signal when you hold it in your hand. There's still a slight drop in reception when you hold the phone, but more of what you should expect to happen rather than a complete drop down to the dreaded X. Still testing it out a for a few days before deciding to drop Verizon, but I sure do like that I can talk and use data at the same time on the G2.

I've had this problem with my new G2. With either the stock ROM or CM 6.1.1 when I hold it the signal drops. This is a non-issue in areas where there's good coverage, but at my house where the signal is quite weak this usually means the difference between signal and no signal. If I don't hold it the signal improves. My Cliq gets better signal here than my G2 does. Also, the Cliq doesn't suffer any noticeable signal issues when I'm holding it.
It's funny, as I go about my daily routine with my G2 instead of my Cliq, I notice these things. I get much weaker signal in certain areas with my G2 where I got acceptable signal with my Cliq.

I don't believe there's an HSPA+ icon. Just H.
Try using the Speedtest.net app to check your speeds. There's no HSPA+ on my network but I still get decent speeds. I just wish coverage was better so I wouldn't switch bands and lose signal all the time. The radio hardware on the G2/DZ sucks!

The only option I have found yet,(limited time to tinker) is to turn on 180 degree rotation and hold the phone "upside down" it seems to work every time.... So when I am in a place that has weak signal and I need to use data, I flip it around, and it works fine.... I know this is lame considering I paid so much for the phone but.... it does work.

[POLL] Nexus S 4G Connectivity

Haven't yet seen a poll on this and I am curious to see if this is really affecting as many as it seems, here on XDA.
Edit: It would appear that it is indeed an issue for 9/10 NS4G owners.

I have poor WiFi reception. I had a Hero and Evo, and my GF has a Shift, and all those devices have gotten good Wifi in the bedroom. A desktop and laptop have good reception there too. The NS is hopeless unless I stand near the door and hold it gingerly with two fingers. I ended up adding another AP in another part of the house just to cover the NS.
3G signal acquisition is a little below the average set by the above devices, but not too bad. I have to be in a pretty marginal area not to get 3G, and the Evo and Shift last only a little bit past the NS' range.

I have only just recently acknowledged this as a problem. Since day one my WiFi cuts out and my time without a signal is always high. Not sure if 3G is just poor because of Sprint, but it has also been a huge battery drain.

What's funny is the OTA announcement does not seem to state that they are working on 3g issues. It is a little unclear, but that 5th bullet point seems to say they are addressing 4g radio issues only!
re:

Hopefully they increase its stability as a result of fixing other areas of the radio? Longshot, I know.

Wifi is the suck. I have had less than full strength 1ft away from the router.
Not sure if it is this phone or Sprints cup and string network but I constantly get random periods of no internet/data throughput. Mainly on 4g. Going through one right now. 4g connects but there is just zero data tranfered. All webpages time out etc. Now on Sprints totally awesome dialup on vitamins 3g network.

For me, all the above. Call me pessimistic but I'm kinda doubting that software will fix a poor radio. Has anyone ever actually experienced an update solving a bad radio? I was actually considering getting a new evo 4g with the extended battery and call it a day. As more days pass by, it seems my network performance gets worse. The times where I'm not getting any data throughput are getting longer. It was annoying for awhile but now this really pissing me off! Cycling airplane mode and rebooting the phone is getting to the point where it doesn't fix anything. Its a waste of time. Like many other people are saying, I love the phone but using it for its main purpose, a phone, it is utterly horrible! Most of the time I have very little signal on the tower, if any at all. I keep saying I'm not going to buy Samsung phones anymore but I still do and continue to get burned by them.

Weird. Now that you mention it I thought the same thing. It just gets worse.
When I first got this phone I could sit on 4g all day long and the internet was just there. 3g too. 100% reliable network activity. Then about a month ago the random periods of no data throughput started happening. First it was both 3g and 4g, now it is just 4g. The 3g speeds are a joke. You can't stream **** with this phone on 3g without skipping and buffering. 4g streams fine but you still have to worry about the data throughput hitting a 2hr or longer brick wall of uselessness.

Luckily i keep my galaxy tab with me because my nexus will show no bars and no data when my tab will be close to full. I just end up using my tab for most of my data use.

If the next update comes and it doesn't fix anything, then we should be allowed to have the device replaced.

My guess is that it is a combination of our crappy radios and sprint is still having wide spread data issues. My gf has my epic and even though she gets more signal and less data loss than I do, she's still experiencing network issues. About an hour ago, I just got a bunch of responses from her that were morning and afternoon and they came in all at once. I sent an email and a text in both stock SMS and Google voice a little while ago and haven't heard anything back yet. Sprint must know they're having network issues. It seems like it has been going on for three weeks now and today is really bad. There are times that I think dial up is faster than the speeds I'm getting when it does work.

Woohoo. Just got 4g data throughput back. Only down for 4 and 1/2 hours today. All good till tomorrows outage. *eyeroll*

I noticed I just got 3g back.

3G and 4G are great! only WiFi needs to be touched up. I use 3G at the home (averaging 2,000 kbps DL) so WiFi isn't needed unless I'm downloading huge ROMs or other files.
Still, I prefer having a working WiFi for friend's houses and other locations.

Jumping From 3G to HSPA?

On T-Mo, stock with root and the phone keeps jumping from 3G to HSPA. Speed tests are reflecting the same also. It's not happening every few minutes, but every couple of seconds. I'm in an area with HSPA and my S3 never switched over to 3G at all.
Anyone else noticing the same thing? I imagine this is going to kill my battery.

Mine seems to do this but tbh more it stays on 3G until i use it, then it switched to HSPA+ and give's me the speed i want to be honest i think this might save battery...

That is intentional, it disables HSPA when it is no longer necessary. (i.e. when not downloading anything)
The SGS3 does the same, it just shows the icon regardless of what the actual state is.

try disabling fast dormancy

I haven't once seen my phone show 3G. It shows HSPA when it's not downloading anything, and HSPA+ when it's uploading/downloading. I've seen it go to EDGE for a few seconds underground in a concrete building, but it soon switched back to HSPA.

I've heard this is intentionally done by T-Mobile, and mine does it too.

This is intentional as the previous readers have posted. Has been this way on all 5 htc phones I've had, and on my Galaxy Nexus. The phone idles at 3g until the request comes for more. Supposed to be battery saving. Make sense?
