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

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.
Sent from my T-Mobile G2 using XDA App
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...

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.

Driod 2 evdo signal question.

I have downloaded both Real Signal and Signal Status from the market. I keep having issues with my data not working(it's been ongoing since I got the phone.), so I wanted to know what my actual dBms were. But for some reason, on both apps, the highest evdo reading I get is about -3 and the lowest is about -30. But I don't know what that means in terms of real signal as everything I can find on google and that I understand, it should be between -60ish and -115ish but I have never seen those numbers on the evdo side. Am I wrong? I understand that it is the same dBm as 1rxtt, and I know they are different tech, but I would think it would be similar any way. However, I don't know antenna tech at all. So that's why I posted the question here. I have done a google search with no real relevant results, but I didn't search XDA specifically, as I thought if there were any relevant results they would have popped up in my google search. And all the relevant postings that I came up with said the same as my assumption. That signal should be between -60ish and -120ish.
Thanks again for all the help, you guys are awesome.
1 bar ~ -102 to -120 dBM

I was able to hunt down that chart (Granted it was for a BB, however I would imagine the info would still roughly apply to any device), but I was not able to locate any real description of bars vs dBM. However, from what I've read before, just because you have a lower dBM (IE: -40) doesn't really mean you're going to have full bars/better service. I could be wrong, but from most of what I've read over time showed it was only a very vague correlation.
Do you get intermittent loss of data where only the right arrow under the 3G icon is active? That happens to me frequently as well and I have to go in and out of airplane mode to reconnect. Some of us think Blur causes it.

Granted, I only kept the stock rom for about 3 days before I installed a custom, blur-less rom. However, I seem to recall having some data issues while using the stock rom. I donno if it was part of blur or something else causing it. However ever since I've flashed to a new rom I havent had a single issue.
I've been having issues with data like this, too. I have put an Airplane toggle widget on my home screen just for this. I am near Fort Collins, CO, but I guess it looks like people may have narrowed it down to ROM issues and not location or Verizon.
Maybe they'll fix it when they roll us out to Gingerbread.

I have wondered myself if it wasn't blur issues. It freezes all the time, and fiancees Ally doesn't have the freezing problem and general laggyness. And I know hers only has a slow 600 Mhz processor and is just a budget smartphone.

Then should it be possible for me to hit single digits? I don't recall ever having a lower signal than -30 and it stays typically in the -8 to -20 range. When I was at about -100 cell service, I was at about -8 to-10 evdo. So something still must not be right with my phone. right now I am at -76 cell and -2 to -4 Ev.
I am seeing the same thing on my phone. I have ~87dBM cell service, and ~7dBM for evdo. I have always understood Verizon's voice and data network to be separate, I suppose this just goes to confirm that.
Here's a way to confirm if it's a problem with Blur, as opposed to VZW's network. Is there anyone who had this problem on the D2 with the stock ROM and then had the problem completely disappear (or at least reduce in frequency) after switching to Liberty ROM, or one of the others?
All my issues dried up when I flashed a custom rom.
I work in the industry. A -80 is generally the number you want to shoot for as far as having a good usable signal. Anything higher would be even better. Although once you get past -50 or so the signal is kind of hot and may cause issues. Anything lower is a bad signal (-90/-100) and would also cause issues.

I had 3g issues with the droid 1 and cyanogen but Never with blur or liberty/droid 2 from the same house. I have noticed some "cell standby" signal loss on liberty but never really bad like some cyanogen builds..don't overclock and see if that helps.

signal strength gives no indication of 4g speed?

Experimenting with modems to try and find a better one and came across something very irritating. It seems after my testing that the number of bars of signal and the signal strength reported in Network Signal Info seem to have no relation what so ever to the 4g data speed you may get.
Earlier I was testing with 4 out of 6 bars of signal, NSI showing 94dbm and something like 60% signal.....and I consistently got speed tests of around 1mbps or less and even that was slow and stuttery. On other occasions with only a 40% signal at 106dbm in NSI I was able to get 22mbps in speed tests. All these tests were done using the same speedtest server as well as subjective testing by running various apps and seeing how quick or slow they were (and the performance of all the apps matched the performance of the download tests). So what the hell is going on? It looks like signal strength has nothing to do with the 4g connection speeds.
Is the signal strength even indicating the strength of the 4g signal or is it merely indicating the strength of the phone signal because that's what it kinda looks like.
I am on EE UK with their 'double speed' 4g (which gives me 97.5mbps download when at home with a perfect signal).

Yes, in fact the signal strength and data speed are different things and they do (most likely) not affect to each other.
By detailed, signal strength is depend on if you are far or near from the mobile tower.
While data speed depend on many other factors: max capability of the network, your subscription with the service provider, and the congestion on the network.
The signal strength will also impact on data speed, but only when you are very far from the tower, when the signal strength is very weak. That may impact the data speed.
Exactly what I was afraid of. This would mean it is not even possible to test how good your signal is (for data) without running endless speed tests (which are going to kill your data usage in no time). There is no other way to test data strength?

The term "data strength" has no meaning. If you want to test for signal strength, it is the received level. If you want to test for data speed, there is no way without actually testing it.

signal bars at Zero?! is this normal?

Hello guys! I don't know what's going on but since I have this device almost every time the signal bars are at zero. Anyone having this issue?
Yep, this phone has terrible reception. Although, the signal bars don't necessarily reveal how strong the signal really is. Indoor reception is worse than outdoor. I have one or even no bars inside my house, but I can still get lte+ speeds. As soon as I walk outside I have full bars, and not much difference in download speed. I have missed more calls with this phone than any other phone I've had though. Really bummed cuz this phone is so close to being the best phone I've ever had.

(On T-Mobile network) At home phone shows more than half of bars, at work, outside and in most places phone shows at least half of the bars. I did see no bars couple of times in few places, but it didn't create any issues. Comparing it to other phones and if dB signal is to be believed, then it is safe to assume that Essential has about -6 to -8 dB less than devices from leading manufacturers.

Yes, I agree. The reception on this phone is super weak

Agree I have a Note 8 and on tye Essential the signal is much weaker.

I'll get this on certain stretches of highway. It will go to no bars, then bars with no internet. I set to airplane mode and then I'll get bars and LTE again.

Yes, sometimes even if I have no bars at all the service seems to function properly. Maybe it's a software related thing.
Right now I'm at zero bars but the LTE keeps working fine. Idk what is going on lol
I live in a fringe area of Verizon. This phone is no weaker than my old Samsung S4.
