dBm range - ONE Q&A, Help & Troubleshooting

Hi,
I'm having hard time to find the dbm range for radio signal on my OnePlus One. Does anyone know from what dBm to what dBm does the signal strength range. I think it is somewhere from (maybe) -100 to -40 dBm, but that's just a random guess.
Anyone?

The highest I've ever seen was -51dBm, and the lowest I've ever seen was about -117dBm. I'm going off memory here though, I don't know the official upper and lower limits.

D2G Signal Strength Screwy?

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.

viewing Signal in DB rather than bars

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?

Bad Data Transfer Rates in Bldg.

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 :/

Signal strength inaccurate Samsung Galaxy Xcover

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.

[Q] Signal and Bars appear lower in CM 12 compared to Oxygen OS?

Hey there everyone,
Apologies in advance if this have been covered someplace, I've been searching forums and came up with nothing.
For some reason I had better reception (more bars) with Oxygen OS than CM 12, but my friend who also has his Oneplus on CM 12 who was sitting right beside me has more bars also. I don't know why that would possibly be... but I'd like the best signal I can get, is it possible to flash a modem in case something went wrong with the update?
I had one bar of LTE in my office, and he had a consistant 2 or 3 bars, same carrier, same phone, both the newest generation of sim cards, and both phone extremely well taken care of.
Any suggestions would be amazing. Thank you in advance!
Forget about the bars, they're unreliable. There's no standard, so you're really just seeing arbitrary measurements that can change from phone to phone, ROM to ROM. The only way to accurately measure your signal strength is by going to Settings/About Phone/Status and you'll see your signal strength there measured in dBm. You must remember though, dBm is measured in negative values, so -115dBm is lower strength than -55dBm.

So the closer to zero you are, the better reception you get (taking into consideration negative values)?
