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.
I believe there is a bug in the signal strength indication on the Fascinate, the one that shows the signal strength in -dBm.
You can see the signal strength of the cell signal on the Menu, Settings, About, Status screen. Or you can place a widget on your Home screen. There are several widgets available, I'm using Mobile Signal Widget.
I have a network extender, which basically creates a cell tower right in your home. With my Motorola Droid, I used to get signal strengths down to about -50 something and 60's in indicated signal strength. I can hold both of our Fascinates right next to the network extender's antenna and they will read no better than -86 dBm. So far I've seen signal strengths from -86 dBm to -106 dBm (terrible).
I believe there is a bug in the software (Baseband) on the Fascinate. Previously, I thought the hardware (antenna/radio) wasn't very good, but now it may be software related.
Has anyone seen a signal strength stronger than -86 dBm on the Fascinate?
That's a good point. Mine has never gone below -86dbm either. It fluctuates between -86 at it's best and -106 at it's worst.
Ill keep an eye on this with my phone

I have no experience with cell phone radios so take this with the appropriate helping of salt.
Most radios have input protection that attenuates any signals greater than a set maximum level to prevent damage to the radio. I'm guessing the Fascinate reports it's receive signal level post input protection. It appears you just discovered this threshold for the Fascinate. Honestly, -86 dBm is plenty of signal, anything more is just for show
Again, I'm only speculating here.

Interesting theory. I have emailed Verizon support as well. Hopefully, I will get a technical response and not a canned response from them.
With mine, it only fluctuates in -5dBm increments lol. I thought it was a litle wierd. I've seen -86, -91, -96, -101, and -106 lol.
As far as what the OP is talking about, my BB Tour (alltel) is the same way. It won't ever display anything lower than a -80.
Anyone else have a consistently high TWS(Time Without Signal) percentage? Mine almost never goes below 50%, and I've seen it up in the 80s. I think my battery life is really suffering from this. You can see yours in Settings > About Phone > Battery Use > Cell Standby. I've tried a few "fixes" that I've found through researching the issue on other android phones in general, but haven't seen any results.

I was thinking about this the other day. Is it possible "time without signal" is simply a poor translation? The reason I ask this is when taking my phone off the charger overnight, I went directly to this setting to see what it reported. The phone reported having been unplugged for 2 minutes and already showed 5% TWS. I had been looking at the phone the whole time and didn't see it drop at all. What I did see is it going from 3G w/ arrows to 3Gd. So maybe this percentage isn't time without signal but rather time not active (i.e. 3G d).
I agree w/ the 3g d, I did not update to DI01 yet and it said I have 20% TWS throughout the day, but the phone didnt make a no service sound.
On my drive home everday I pass a Verizon owned tower.
I've stopped at a liquor store about 200 yards away from it and they maximum signal my Fascinate would pull down was -86dBm (4 bars as well).
My Cell Standby is usually around 11%.
Battery life of my Fascinate is very good.
xliderider: Any news/word from Verizon on this? What kind of Network Extender do you have? Got a brand/model #? Been thinking of picking something up like this.
So it isn't just my phone. My Fascinate goes from -86 to -106 as well. I had my Droid and Fascinate sitting next to each other, both reporting 4 bars. I went into status, and my Droid's signal strength was -77. The Fascinate was at -86. It's gotta be capped.
You're holding it wrong.
Sent from my SCH-I500 using XDA App
You are probably right. With 4 full bars I can't get better than -86
I've been having the same problem...I was told by Verizon that it just has a "weaker" antenna. I go throughout the day with about 20% TWS. Never had that with my other Verizon phones.
do you get dropped calls or otherwise poor service?
I am returning my incredible due to dropped calls (while at home) using Verizons network Extender. I have had the incredible since April 29th (I believe that was the first day it was released). I have had the signal boosted twice by Verizon but still can't get close to 40' without dropping. One thing I noticed on the incredible while in the same room with the Extender is it would read let's say a -86dbm before placing a call then when placed and on the Extender network the signal would automatically go to -56dbm (stronger signal than -86dbm) and then back up after my call. What I saw was the Extender wasn't active until you make a call... Having said that, I am hoping the Fascinate will be better than the inc was... I will let you know when the Fascinate gets to me Wed or Thursday.

Sounds like it could have the same problem that affected the Vibrant. It NEVER showed higher than -81dBm, and would often reflect no signal (-0dBm is spectacular but it really means no signal within the Android system). Now with the update it reflects up to -51dBm like it should for GSM/WCDMA with Android and doesn't drop to -0dBm anymore. This of course effected the bars, often dropping to no bars or 1. Now after it's been fixed, plenty of bars and proper -dBm readings.
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?

I get poor reception on my Incredible whereas my parents get great reception on their phone. A little googling and this popped up:

I was thinking the same thing but trying to be hopeful ya know? I really need some signal boost. I average around -90 dBm
If you're desperate, it's not like $2 is a huge sacrifice for a likely useless piece of plastic. I don't know I usually get between 80-100dBm at my house and i have no complaints about the service... The bars don't necessarily tell the whole story. 85dBm is 5 bars on my 6bar signal meter, so keep in mind that bars don't necessarily tell how mcuh signal you have. With the stock 4 bar meter, I would never have 4 bars at my house; usually 1 or 2; sometimes 3.

I go by the dBm and just sitting my room I can go from -85 up to -120
I always thought that it would be normal for my dBm to be in the -60 range. Am I wrong or is -80 to -90 okay?
I get -91 to -106 in my room and I have good enough signal to do anything I want. Also my friend bought one of those for his Eris and thinks it actually hurt his reception but I can't imagine there's a difference with or without it

If you want something to boost your signal this is one of the only things I've found that will actually do it..... http://www.tigerdirect.com/applicat...CODE=GOOGLEBASE&cm_mmc_o=VRqCjC7BBTkwCjCECjCE
They are normally priced at $120 but can be had for $15. I bought one and currently use it in both my vehicle and home. It will boost the signal for me from around -105 dbm in my house to around -90 dbm, but I've seen it get as good as -81 dbm. I plan on buying another that way I don't have to keep moving it around.
They say it works within a 6 ft radius of the plug but I've found that you need to be a little closer than that to it.
-80dbm is the best signal possible. Also, cdma signal fluctuates. Don't expect it to stay at a consistent number. Unless you're having issues with dropped calls or slow data, I wouldn't spend another second concerning yourself over it.
Thanks for this... now would two of these work better then one?

I've never seen mine better than -78 unless it was some weird fluctuation for a second
0 would actually be the best possible. But it can never happen, so, meh.

Your head absorbs wireless signals.
So, use the speakerphone more often, or better yet, use a good quality Bluetooth ear piece so the phone can sit near a window still.

keep in mind that CDMA phones with VZW use two radio frequencies. one is voice, the other is data. so the "bars" and 3G doesn't do much to specify which of those two network connections its representing. my guess is that it's representing data strength, not voice.
-80dbm is the "best" signal strength i've ever seen a verizon wireless cell phone have. and that's based on other phones, such as blackberries, winmo, etc...i'm not sure if it gets any lower than that on CDMA networks. i know my WI-FI, when at the strongest, is usually -40 or -60 dbm.
for example, sitting at home my signal is -84 dBm, and that is pretty much full strength
also, the value we are discussing is how "loud" the signal is. take into consideration that network traffic will also impact service in varying ways.
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.

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.

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....
Cheers

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.
