Prl here in Fortlauderdale went to 3023 OTA (Over The Air)
~~~~~~
Something Interesting!
I Noticed that when my bars Went Up,
my -dBm signal strength # Went Down.(menu/settings/about phone/status... scroll down to signal strength)
and visa versa
I assumed the higher number(-101 dBm)meant a better signal.
then here
Cellumap Cellular Coverage Maps I hovered over the (information circle)above the Signal Strength button
and saw a chart that showed different.
I've since learned that>> The lower the -dBm number is, the stronger the signal <<
-65 dBm is a good signal
where
-101 dBm is considered signal lost.
I've read that the -dBm value has to do with only the Voice signal(bars) and not the Data(Internet)
& not really clear on what effect the -asu #(Active Set Updates)has on either Voice or Data.
=======================================================
Taken From:
Signal Strength dBm?
the lower the number, the better.
So for example, a -50 dBm, has less signal fading form the nearest tower than a -90 dBm.
A 0 dBm, which is near impossible to achieve unless your climbing the tower, is 1 milliwatt of power. For every -3 dBm the power is being cut in half. So a -3 is a 1/2 a milliwatt, a -6 is a 1/4 of a milliwatt, a -9 is a 1/8 of a milliwatt, and so on....
A dBm in the 90's is the bare minimum to sustain decent call quality. In 100's and you dropping calls.
Our phones work on a 4 bar system, but I located Blackberry's scale so that you have an idea of the dBm to bars ratios.
1 bar ~ -102 to -120 dBm
2 Bars ~ -93 to -101 dBm
3 Bars ~ -87 to -92 dBm
4 Bars ~ -78 to -86 dBm
5 Bars ~ -40 to -77 dBm

"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."
=========================================================
still trying to figure out why 3g is getting "Suspended" while on the phone.
(menu/settings/about phone/status... scroll down to Mobile Network State)
2 weeks ago I could be on the Phone and use the Internet at the same time.
