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 get poor reception on my Incredible whereas my parents get great reception on their phone. A little googling and this popped up:
http://www.onlyincredible.com/incredible-booster.html
is this legit at all? i'm not a technical guy so I have no idea.
I call bull****. They used to sell these things for regular cellphones. They didn't work then, either.

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 know people here don't take bars for much, but why is -80 only 2/5 bars if it is all i can expect? I've only had a couple dropped calls so you are probably right that i shouldn't worry about it.

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.
As far as highest signal strength possible, I've been in the -30's before. That's the highest I've ever seen.
Same, -32 was my best

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.
so here i got 3 Android phones
all sitting on the same spot
2 of them (SGS / XT720) shows 3 or 4 bars signal strength, but SNS only shows 1 bar, 2 at best.
however a quick test using 3G speedtest confirms the same download/upload speed as the 2 other phones.
and there's no problem calling even when it only shows 1 bar.
Can any body confirm this?
Go to settings > about phone > status and post the signal strength of each of them (should be in dBa). If they're the same, then ya either the SGS phones are overinflating their strength or the Nexus is reporting lower than it should.

seems like it is displaying signal strength wrong, I believe it is the farther from 0 the better the signal
im at -75 and full bars 3G
anyways... that's what i'm saying the actual usage is good, and 3G speed is good
but the bar indicator is always like in 1 bar or 2 bar... which is kinda wrong

try restarting your phone? so it re-associates itself with the network
that would have been the first thing i do when i try to nail a bug
that's why i wanted to hear the experiences from the rest of you
just trying to find out if this is a bug specific to my phone, or if it's something that is affecting everyone
-97db with three bars displayed here.
Sent from my Nexus S using XDA App
The farther it is from 0 in the negative, the worse the strength is. The best strength I've ever seen on an android phone was -69. Worst is in the -100's so it looks like the Nexus is actually getting worse signal, not just reporting worse...maybe an antenna problem =(

quite the opposite, 0 is just a reference point, the farther from zero the better
Mine is -101 with 2 bars.
I'm not sure where you're getting this from, but you're saying -100dbm is better signal reception than -70dbm? If that's the case then the signal strength reporting is completely reversed... as I have full bars in my apartment and it shows -72dbm, and at work I have 1 to 0 bars and it says -101dbm. It's been like this for all of my phones.
Also speed tests at home give me 500k/s down and 50k/s up while at work I only get 60k/s down and 20k/s up...

It seems like the SNS is getting far worse ACTUAL reception than the other two phone.
-107 is very bad comparing to -97 and -84.
Are all 3 phones on the same carrier?

That's interesting as there is a huge difference between the SNS and the XT720.
-84dbm means very good reception and -107 is at the end of the workable spectrum (at -113 you basically can not place calls).
I am also noticing very bad reception on my SNS but i thought that it is due to T-Mobile's crappy network. i have no other T-mobile device to compare it with though so i start to wonder if its the Nexus S that has crappy reception or T-mobile.
Try to do more tests in other locations with the XT720 and the SNS and see if you always see such a huge difference when both devices are in exactly the same spot.
I am interested in your findings.
And as for your initial question, there is no bug in the signal indicator as -107db is very bad signal so the indicator is correct.
Okay please allow me to clear up some misunderstanding in this thread...
First of all, dBm is a logarithmic measure of signal strength with respect to 1mW. So, a smaller (i.e. more negative) reading means that you have lower signal strength.
Just to give an example: -50dBm is a much better signal than -100dBm.
Alright, so now let's move on to the next issue: You can't compare signal strength on two phones which are running on different networks. Why? It's possible that you have a strong signal from Fido and a weak signal from Wind, or vice-versa. If you want to compare the RF capabilities of two phones, you should make sure that they are connected to the same network and even the same cell (you can check the service menu to make sure that they are on the same cell).
And finally: The Settings>About Phone>Status is usually not a very accurate measure of signal strength, since they are rounded off to some pre-determined list of values (So for example, if it is jumping between -100 and -110, it might actually be jumping between -104 and -105). You should instead go to the phone's service menu (i.e. you type in some code into the keypad) where you will get an exact measurement.
My friend happened to have the XT720 while I have SNS, and we happened to be at a same location where my SNS can't maintain the connection (only able to connect at one room spot with 0 bars and unable to hear a thing due to choppy voice when I tried to check voicemail) and XT720 still got 2~3 bars anywhere in the room and able to make phone calls. We are both from same carrier. We left our phone on table side by side without touching it. So despite the bars on phone nor the signal number in setting menu, real life experience tells me XT720 does have better reception than SNS sadly D: I was embarassed that night when other friends laughted at my supposely better phone
Reception is important to me since where I work I can not hook my phone up to wi-fi and reception can be very spotty. I am trying to gather some numbers regarding the M8's dBM numbers for reception compared to the S5.
If any one has the ability to compare the data dBM reception at the same time, with both phones next to each, will you please report your numbers.

No, I do not, the one guy who has one at my Office is out today, unfortunately. But I thought I would toss my number out there for compare standard to extended battery as well, should you decide to get an S5 and want an extended battery.
Good luck. :good:
I went to a Verizon store and the S5 had a little better reception about 1-2 dBM better. M8 dBM seemed to fluctuate a little more, while the S5 was pretty stable.
So, I just did a speed test with my son's HTC One M9 and my Axon 7.
Test were done at the same time, even though the screenshots were 4 minutes apart.
Both phones on my desk, 2 feet apart, ran at the exact same time.
Notice the HTC with 5 bars of signal, my Axon 7 with only 2 bars. It was like that when I did the test too.

[EDIT]
For those curious, the Axon 7 is louder and sounds far superior than the M9..... Just figured I'd share that.
Recently I've seen a few posts about how "bars" actually matter in signal strength. Please note that each manufacturer has different minimum dBm boundaries. So -60 may be three bars on one phone, only two on another. It's still -60dBm

It's possible that the M9 was connected to a different LTE band from the Axon 7 - if the M9 was on band 17 (12) or 5 and the Axon was on band 4 or perhaps 2 it may be the reason for both the difference in signal strength and throughput. Not sure though...definitely an interesting contrast either way!

While that is true, a bunch of users on this forum and zte forums have done db tests, and the axon 7 (U) is typically worse than other phones. The U (usa) varient also has half the wifi speed that the G (eu/general) model has (see aida64)
