[Q] Sporadic Signal Loss - HTC Aria General

Okay so i've got an aria rooted and flashed with the Liberated 2.2 rom. I've been using it for the past 3 months and I've noticed that I will go from full service while a phone call is comming in and complete signal loss when I answer it. I have set the phone on a table and watched the network signal strength go from -113 dBm and 0asu to -81 dBm and 16asu and vise versa. I have also noticed that when I lose signal my "H" for the data goes with it and service comes back a few seconds later very strong but showing "G". From there it will go to "E" then back to "H".
Could anyone explain this or have a better reason as to why this is happening? Maybe its just based on the connection where I live but I've used the app Antennas and the tower is about 1/3 mile away.
Any info or help would be awesome
Thanks

i'm not sure why this would happen outside of a poor bit of service where you're living.
i used the various roms for the aria and never had any sort of service loss issue.
as far as the icons switching around, e = edge network (2g), h = hspa (3g). when your phone drops its connection, it tries to reconnect as fast as possible, usually with edge, then after its strong it looks for the 3g connection.

question about 2g and 3g and service

Hello All,
I just recently purchased the AT&T nexus one and I just want to make sure my understanding of my question is correct or not. I have noticed that when I am at my house and if I have 3g enabled the signal bars next to the 3g icon are somewhere between 2-4 bars and are always fluctuating, But if i enable the option for use only 2G networks obviously the H or 3g icon disappear and the EDGE icon shows up but the signal strength is at a full 5 bars all the time not fluctuating. It was my understanding that the signal strength bars were completely seperate from the 3g or 2g icons. I thought that the signal strength bars represent my cell signal and whatever icon showed up was the data coverage in the area but they aren't related? Is this correct or is it that the signal strength bars represent the signal of the 3g or 2g?
The signal strength bar represents the 2g or3g signal strength.
Both of you are correct. To make calls or text the signal bars are need to use data the icons are needed.
But you don't make calls on 3g or edge. So I don't understand why the signal strength bars are lower when on 3g as opposed to edge unless its wat the first Guy said. And that doesn't seem correct cause that's basically saying my cell service is worse and I would have a higher chance of getting dropped or no calls at all when I am on 3g as opposed to edge.
not sure about your networks but on every other 3G network you make both call and data,,,

A couple of notes here:
- All you're seeing here is that 3G service is weaker than 2G/EDGE service at your house. Perhaps there are more EDGE towers around you than 3G-enabled towers, or EDGE runs on a lower frequency such as 850MHz that penetrates through walls better.
- If your 3G service completely drops out, you should fall back to EDGE during the call. There shouldn't be any interruption, but there's a small chance that the call will drop when this happens.
The latter happens to me on TMO all the time if I go into weak 3G, and I've never had a dropped call or issue because of it - so really, as long as you have solid EDGE service, phone calls shouldn't be a problem for you. Note that when you fall back to EDGE, you can't use data while on the call, but if you're still on 3G, it's possible to do so. You can of course combat by this by just using wifi.
Now, on the other hand, AT&T's 3G network is overloaded in some markets, so you may have a dropped call because of that - but that's a different issue altogether.
gsvnet thanks a lot! Cleared up everything I was wondering.

cdma signal preference

I know its kind of against how cellular is designed to work but I am in a situation where a sprint signal is only barely(0 bars) available and it decides to roam (with the triangle) to a uscellular signal. The problem is that its constantly trying to stay on the sprint signal, realizing that the connection isn't good enough and goes back to the uscellular signal and is just killing performance and battery. Is there any prl update or fix I can make with the evo to just stay on the uscc signal and forget about the crappy sprint signal at this location instead of hopping between the two? Ideally I'd like something automatic but I would even settle for a toggle. The uscellular signal is a repeater that was installed at my workplace. For example, in battery status my evo; the cell standby is at 39%
I am having the EXACT same issue in my office. The repeater signal in my office (850 MHz so it only repeats Verizon / AT&T / T-Mobile) is -70 dBm (full bars on my phone). The Sprint signal from outside through the foot thick cement walls is -102 or worse dBm (aka 1-0 bars). Why the hell will the phone not consistently stay on the higher power signal??
The techknowfile trick is NOT the solution to this problem. This seems like a problem with the phone itself - the whole point of a multi-band phone with free roaming is it should always pick the best signal (in my opinion).
I tried the techknowfile trick as well with no luck. Maybe a different prl? I used the 40060.prl file suggested.

3G signal problems with certain CIDs

Hi, I have a problem that I suspect is an isolated situation, nevertheless, it has been bugging me for over a month now. Hopefully the community will have some insight.
I will try to report the problem in it's entirety:
I do have a shortcut on my desktop to Phone Info (*#*#4636#*#*). From here, the thing I note of interest is the CID, which I guess is the tower ID that my phone is currently connected to. Also of note here are the ASUs, which I'm not quite sure what they are, but they seem to correlate with the number of bars being reported (ie more asu = more bars).
I also use Hello IM (AIM app from the market) heavily, and I have "Show notification icon" enabled, so it works fairly well as a visual indicator of connectivity, or lack thereof.
Ever since I upgraded from Super D to an Eclair rom, I've had problems with 3G handoffs on Tmo. Basically, whenever my phone switches from Edge to 3G, or one 3G tower to another 3G tower (different CID in Phone Info), the connection times out. I see the infamous "up arrow but no down arrow" activity on the 3G icon in the notification bar. This happened just about everywhere I went.
About a month ago, I decided to upgrade the phone radio, from 2.22.19.26I to 2.22.23.02. For one reason or another, this completely solved my problem. I had no problems with handoffs, 3G just started working again.
A couple weeks ago, I downloaded CM6 and tried out Froyo. The first thing I notice is the weak signal on my radio. Before flashing the rom, I did a nandroid backup, and I know I had 3 bars of 3G signal where I set the phone down. After the flash, my phone had no 3G signal, and for some reason refuses to switch to edge; so my signal indicator is sitting there with an X over it. After some time, it finally does pick up a 3G signal--this is where it begins to get weird...
My 3G works right now, for the most part. There seems to be 2 very specific locations where it does not work. As mentioned earlier, I am able to check CID's through the Phone Info menu. I notice 2 CIDs where my 3G connection times out. By time out, I mean an apparent loss of data (ping doesn't work in Phone Info). This happens every time I am connected to these 2 towers. As soon as the phone switches off to another tower, data works fine again. The strange part is, even though I am not getting data, the asu and signal bars continue to move up and down as if I have a normal signal. The phone also makes no effort to switch back to Edge, even though 3G data is completely stalled (Hello IM shows as disconnected, ping fails).
This started happening since the CM6 update, and have persisted since then. Even after I did a nandroid restore back to my previous rom (Super E 1.02), the radio problem remains. Before CM6 and after I updated my radio, I had no problem connecting to these same towers.
In a nutshell:
3G does not work when I am connected to 2 specific towers since CM6 update
Phone makes no effort to switch to other 3G towers or Edge when connected to these 2 towers
When connected to these towers, signal strength continues to go up and down as normal; usually hovers at a consistent 2 to 3 bars with the stock signal indicator (4 bars max).
Currently I have tried flashing all the Eclair roms available, as well as my old Super D rom (still using 2.22.23.02 radio). Problem remains.
Does anyone have any idea what's going on?

[Q] Signal Management

I have both mobile signal widget and netswidget installed on my home screen, and either something new is started or I missed it before.
Is the G2 ACTIVELY managing the difference between UMTS and HSDPA?
With these two widgets, I see the phone in 3G (UMTS) and when data exchanges (email delivery for example) it goes to H (HSDPA) and then exchanges the data and then goes back to 3G. I have seen this happen a lot of times, so it is not coincidence or signal issue.
If the phone is doing this, could this be a contributing factor to the problem with signal? I have seen a lot of people post that they have a reboot or signal lost right after doing some data activity. Could it be the switch from H to 3G and back that is causing a problem, maybe if the HSDPA is not that strong?
Just throwing out ideas trying to troubleshoot these issues.
My N900 did the same thing. If it sat there idle it would stay on 3g but if there was data being sent it would bump up to 3.5

Puzzling coverage...

I'm on the Three network, have an unlocked HTC desire HD with 17 m2 radio.
Normally I get terrible signal in the flat that i live in, its a granite building in Aberdeen. Occasional the signal is around 1 bar, sometimes grey, and most of the time its X.. (no service), but i still manage to get 3G or H. When looking at the APN settings and specifically at available networks when doing a manual search, next to 3 is a green star which I assume means it's connected to 3 mobile network. But sometimes i get amazing signal, full bars, which puzzled me! so I looked at the available networks and next to 3, there was no star, so i tried calling a number and it rang and came through. I also tried using mobile internet when in this "good coverage" state, and google would not load (G is displayed in the notifications bar). After a while, the bars would drop to 1 or grey, and i would then get H or 3G, and google loads again. What's going on? and how can i take advantage of this when i have no signal.
try and find the app called open signal maps
that can be used to see where the signal-towers are
and how good the signal is
or use this site and search your adress

The antenna is really wierd.
Normally I only get 2G connection.
But if I completly take my hand off the lower cover and lift the phone up a bit for a better signal, I get a 3Mbps connection, though as soon as I lower my phone back to normal the 3G signal is completly gone or gets really bad (zero bars and lower than EDGE speed)!
The antenna in this phone sucks really bad, my old Nokia phone atleast had a stable connection.
This is very bad news... I was considering DHD, but if there are isseus with gsm signal than I am really worried... Is it also happening on the stock ROM?
As long as network coverege is good you should be okay.
I swaped my SIM card with a friends and with better coverege, 3.5G worked good (solid 2Mbps), only slight drop if SIM cover is completly covered, which doesn't happen in normal use.
I just can't understand how I can get such high speeds with my SIM while on a badly covered area. haven't tested how well other devices pick up the 3G signal (my old phone wasn't 3G yet)
I'm still using stock ROM btw.
Have you tried a different radio?
People are reporting different results with them, so might be an idea to play around and see if anyone of them works better for you
I've tried the new Orange radio and I'm getting better signal, although threes coverage isn't great I would expect the device to seamlessly change between 3.5g and gprs but it doesn't it'll get stuck on hsdpa network until the x appears and sometimes it'll go to gprs and go back to three bars. Before it would be on x all the time and that's probably why the battery was quite ****. 3g doesnt penetrate buildings very well and I live in a granite building so would explain why I get better gprs signal. I just wish the antenna was smart and changed seamlessly.

So annoying dhd still not selecting the next best connection just no service but if I select to detect network automatically it connects eventually
