    Signal Strength Question

    Advertisement



    I'm just curious about the indicator on the top right of the screen.

    Is that the indicator for the voice signal strength or the data signal strength, or maybe they are the same thing.

    I guess another way to ask the question would be if you can talk on the phone that means you can use data and vice versa?

    Thanks in advance.

    Re: Signal Strength Question

    The signal strength effects both data and voice services, as it is a measure of the signal getting from the tower to your phone and vice versa,

    As for what features are available to you I think it depends of your service provider, I use Cingular which shows one of 4 things under the signal meter

    "gsp"- voice only (maybe sms)
    "gprs"- voice, sms, mms, some internet
    "edge"-voice, sms, mms, internet
    "EDGE"-voice, sms, mms, faster internet

    These are however only my observations, I'm not sure if I am exactly correct,

    One neat signal trick is: on the home screen, hold alt, and type bnmll (pressing the "bn" key twice) this turns your meter into a numerical representation of signal strength, other than that it really has no use... But I thought it was cool, oh and just hold alt and type in the same thing again to switch it back...

    My carrier is tmo. are those 4 things you mentioned still apply?

    If you go option -> status then you can see the signal is -83dBm.

    Is this the same number as shown when you use the alt+bnmll?

    what is dBm anyways?

    Hmm, I'm not sure if tmo uses the edge network or not, I'm sure they do but they probably call it something else. signal strength effects both voice and data, but data is the first to go, when you're in a weak signal area it will drop down to the gprs or gps networks where voice will work but other features may not, as for what dbm stands for I'm not sure, I do know that the number shown in options is the same number shown when you use the bnmll toggle, I like it because it gives you a better idea of where you stand, instead of a number of bars (1 through 5) it shows a number from 256 to 1, the lower your number the stronger your signal, I find mine usually stays between 90 and 70 or about 4 or 5 bars

    TMo is EDGE, at least here in the North East where I am.
    Here's an excerpt from a pdf I have. I think I got it off of the TMo site, but I don't remember exactly where.

    Re: Signal Strength Question

    This is for cingular

    "gsm"- voice, sms
    "gprs"- voice, sms
    "edge"-voice, sms
    "GPRS"-voice, sms, mms, internet
    "EDGE"-voice, sms, mms, faster internet

    The lowercase gprs and edge means that it can see the network, just can't attach. If you notice you're not getting email and see GSM, lower gprs or lower edge, hard reset and it should be fixed.
