Recently I found the CM7 option to change my signal meter to be displayed in DB rather than bars. I have found it very interesting as it gives me a much more accurate reading of my signal strength or lack there of.
When sitting at my desk my reading is -95 DBm ( terrible data coverage )
At the gym I get -63 DBm ( excellent data coverage, with streaming netflix over 3g / 4g )
I am thinking about trying some different radios to see if that makes a difference.
What kind of readings is everyone else getting?

Okay so I've always known my D2G was a little off with its signal strength especially how it represents it, and I know that all cell phones represent the number of bars based on signal strength differently. However as far as I understand it is still a cut and dry system within each phone, so for example -75 dBm should always be a certain number of bars on a phone correct? Yet my D2G does not seem to think this. I have only been carefully monitoring it today. However Right not is has been bouncing around -62 dMb at 0asu to -69 dBm at 0 asu. It increased from -69 to -62 and stayed at 2 bars the whole time for a while, now it is at -64 and is showing 1 bar. How can -64 be 1 bar is -62 was for a good 30 seconds holding 2 bars? Isn't -62 stronger? Also this morning it moved around -65 to -69 and 1-4 bars at random where the numbers seemed to have almost no correlation to the number of bars. Is this at all weird or am I just crazy? This really has me missing the T-mobile G1 which had much more normal signal strengths and made much better sense of them.
I have considered installing the Fission rom, but before I do that does anyone thing an SBF would be worthwhile to have a fresh install? Some people have claimed that seems to help with their phones, I was wondering if it might help with mine too.
Also as a side note, my phone's 3G speeds seem to drastically increase when the phone shows 4 bars of signal, download goes from maybe 600-900kbps up to 1.3-2.0mbps, regardless of what my phone says the signal strength is. However upload is always the same, so at 1-3 bars upload is always faster than download or close to it which seems weird to me.
One last example, my phone just in like 5 seconds went from -64 to -65 to -65 to -66 to -68 and the bars for those were 1 then 2 then 3 then 1 then 1. It makes no sense if the signal is getting weaker consistently for the bars to increase with each decrease then suddenly decrease.
Is there any way to boot WiFi reception on cm7? I love the Rom, but WiFi is a bit sketchy. I'm using the stock radio.
I switch to stock and its way better!

I've tried multiple radios and multiple ROMs (including stock) but I haven't found much difference in wifi signal strength. In theory, a ROM should not impact signal strength since this is at the radio level. However some ROMs might display bars differently for a given decibel level. Therefore, you should always use decibels (not bars) when comparing wifi strength, using a program like WiFi Scanner or Network Signal Info. ROM A may display an 80 dBm signal as 4 bars, where ROM B displays the same signal as 3 bars.
Is it normal for the Mbps of y connection to go u and down so much? Seems like it wants to drop to 1 MBPS and hang there. This causes my internet browser to be very sluggish. Am I missing something?
I've noticed it also in my anecdotal experience:
At a far end of my house with CM7 and stock radio, I get sketchy Wifi reception (phone flips between wireless and wifi.) Can't surf without disruptions as wifi connection gets dropped and have to wait for the phone to get on 3G.
With stock ROM and stock radio, I can surf without any issues on wifi at the same location.
Theoretically, ROM shouldn't make any diff, but I'm seeing otherwise in practice.
I work in a downtown Dallas office building and am running radio 12.39a.60.19u_26.06.06.30_M on AOSPX ICS rom. My signal strength is at -89 dBm 12 asu, yet I have a difficult time getting a consistent transfer rate from my phone while at my desk. The data package also switches between "3G" and "H" occasionally. My battery life is okay, but Speedtest.net is reporting a download speed of anywhere between 512 and 781 kbps and upload speed of 739 and 1038 kbps. It's very inconsistent and sporadic.

Bad signal, interference, los to tower issues, a lot of people on same tower during peak usage. Pick your poison.
How does it perform outside the building? If it performs properly then it's just any or all of the mentioned causes. If it's still bad, then we can work on that. I personally get no signal for the 9hrs im inside my building at work, walk outside, 3g with full bars lol.
There are little tweaks you can do, keep phone in upright position (creates antenna alignment'ish to the tower), you can remove the case as well, (each layer the signal has to go through reduces it's strength)
I figured as much
And it does seem to work fine outside of the bldg. The only problem is that most of my coworkers' devices work fine in the bldg. They are on different networks. I'm on AT&T.

You are comparing apples and oranges. My company has a repeater installed in it for verizon, so all the verizon people get perfect signal. Something similar may be at your place. either way, i dont see a problem that can be fixed on your end, other than switching networks :/
I have this "problem" as in the title. The signal dBm reading is inaccurate and certain app needs more accurate readings. When there are four bars, the dBm is -89dBm, and three it's -93dBm and one -101dBm and zero -111dBm.
The signal strength reading is dependent from bars.
My app needs more accurate readings between the bars, for example -90dBm and so on. How to improve it?
Hope you understood, it's a very little but annoying issue.
I notice thay if i turn off LTE, I get a stronger cell signal on H+. Would I get better battery life by turning LTE off when im using home wifi? I dont lose the signal on LTE or HSPA, but the signal is a bar or two higher normally on HSPA
I believe LTE gives better battery life pretty close to/on part with WiFi levels. Future LTE modems coming out are going to be more battery friendly than WiFi.
LTE>3G as long as there is strong signal if not stick to 3G I guess.
The number of bars is arbitrarily set by the rom for a given dBm and can't really be compared between 3G and LTE. LTE will still function well at lower signal strength than 3G.
