How do you test your Modem for better GPS/Voice/data?

I'm posting this incase it helps any one else, this not a fix and i have no hard evidence that this will make any modem work perfectly, its all depends on area of the country you are in.

With that said, I usually change my gps.conf file in system/etc with the one I posted previously which basically the same as crt60's link at the bottom of post#2.

I also install 2 free apps "GPS Test" by Chartcross Limited (ver 1.2.4 or later) and "SpeedTest.net" by Ookla to assist in seeing how a modem I've just flashed via CWM is functioning. I'm going to assume that you installed the apps already. I run 3 basic tests to give me a pretty good idea of how the freshly flashed modem/rom/update is going to behave without taken a 6 hr drive to Boston (which I do often for work).

Test#1: How is my Wifi acting?- enable wifi on your phone (d'uh...i know)

- open Speed Test

- hit the Tools button (at the bottom) and set unit of measure, (for Wifi, I set it to Mega bits per second {Mbps})

-The "Change Server" button (at the top) is very useful as you may pick the local of where you are testing to, its also list the distance the packects are being set, also the closest server isn't always the fastest, so run several test against diff servers/locations. OK.

-hit the Speed Test button and hit Begin Test

What you are looking for is a avg of your Ping time, Download and Upload speeds. So if you run 5 tests and all were about the same results you can be pretty sure thats what speed you are getting on avg. And yes time of day and net traffic, all that stuff applies, but remember we dont care about 1 score, we care about overall performance. So if your scores were in the WOW range, you flashed a ROM or a Modem or even a Update (hi crt60) and you feel your downloads are slower, run the speedtest, oh and no worries about remembering how you did before, the app keep track of results till you flash a new rom or wipe the results from the app itself.

So whats a poor/good/WOW score,

(scores are listed as Ping/DL/UL scores)

POOR on wifi:

200ms / 1.98 Mbps / 1.22Mbps

GOOD on wifi:

35ms / 8.39 Mbps / 1.84Mbps

WOW on wifi:

24ms / 13.46 Mbps / 1.92 Mbps

So you ran a few tests and got about the same scores, you flashed a new modem, and the scores are much slower, well, flash a different modem and re-run the tests to see how it does. As long as my DL speeds are over 10 Mbps, I consider that a good modem FOR wifi only!!

Now you could repeat the test above but this time leave Wifi OFF, this will show you what you are paying you carrier for. This is really the subjective score, cuz it really depends if you are in a 3g or non-3g area at the time of the test. My take is that if wifi is in the WOW range 3g should be ok, however that is not a rule more of a guideline.

Test #2: Hows the GPS?: ( I assume you looked at the link crt60 posted and config'd Angry GPS (agps)

-enable GPS

-open GPS Test

-and WAIT!!

-you should get at least 1 sat unlocked (u know its unlocked cuz the bar is gray) in the first 10 - 15 seconds once the Chartcross splash window disappears

-with a WOW modem, you should get 8 - 14 sats that lock (the bars turns color based on how good the connection are to each sat and the upper left "GPS Status" turns green).

- if it is taking longer than 45 secs to get a sat connection and you did the gps fix from post#2, from GPS Test hit the menu button on your phone, select Settings and hit the "Clear AGPS" button, "this clears the AGPS aiding data from your phone and should be done if your GPS takes a long time to get a fix".

Test#3 How do I sound? Like I'm in a tunnel or a can?

- make a phone call to someone that you speak to often from your cell and ask how your voice sounds (dumb i know) but just because you can hear them clear doesn mean you sound clear.

This is my basic test I do to acces my phone after a change to ROM/Modem/Update and before I begin the restore process.

Hope this helps. Merry Xmas!!
