    Is anyone familiar with what test equipment is available for testing cellular coverage in a given location? Something handheld would be ideal.

    My company is looking at a solution for transmitting data using the TM network, however, before we do that, we need to know what kind of coverage currently exist.

    We're looking at Panama City, FL and Anchorage, Alaska.

    Thanks,

    guzzel

    TMO has a oretty good interactive online coverage map on their website. I'd try looking there first.

    Hey welcome to wireless advisor! Your looking for a way to get cell signal readings, correct. You can generally do that on most phones by enabling "field test mode." This will give you a reading of exactly how strong the signal is in a given area. You can do this fairly easily with a motorola gsm phone. Another thing is that T-mobile has got one of the best coverage maps in the industry. Check it out @ http://compass.t-mobile.com and hit no when it asks you whether or not your a dealer. Good luck.

    Jay,

    Thanks for the reply.

    I did look at the coverage that TM shows on their site, however, what I really need is a micro view of the quality of service (signal strength) specifically at the various work locations (i.e. inside enclosed buildings, inside hangers, around aircraft; basically all around an airfield).

    Was hoping for a handheld device where I can quantify the coverage based on signal strength, then be able to graphically map out the results.

    Do you know of any device that would meet this requirement?

    Clock,

    Yes, obtaining cell signal reading is exactly what I need. Funny you should mention the Field Test Mode; I have a request in to Motorola for the code to get out phones into FTM, however, no one at Motorola seems to know how to do that with the phone we have. We have the Motorola 280.
    Is there a site that would list the codes for this particular model?

    I would ask over in the motorola howard forums page. If anyone knows, they would.

    You have to hack the phone usually to enable field test on Motorolas.

    Try this though, sometimes it works, and you don't have to hack the phone:

    (This all has to be done very quickly)
    press Menu (top middle button)
    press 00**83786633*

    Hit the menu key, and the key to the left of the menu key quickly to toggle in and out of testmode.

    Jay,

    I tried putting in the code, however, there's no response from the phone.

    I did get a hold of Motorola's customer support (located in Argintina), and his research revealed that the Motorola 280 is not capable of going into FTM. Not sure if that's entirely accurate, but if so, it would explain the lack of info I'm getting from Google searches.

    I just looked it up on Phonescoop and that is a really old phone. It is possible that it is not capable of field test. You can get a V180 cheap on Ebay and I know they are capable of filed test.

    Myself and the other engineers in my office were wondering when this phone came out, and according to Phonescoop.com, it was blessed by the FCC in May 2001. Didn't know about that site 5 minutes ago, so thanks for passing that along.

    Unfortunately we can't go out and buy another phone for what we're using it for, as this phone is very specific in nature, (http://www.gdc4s.com/content/detail.cfm?item=97aef0a4-96e4-4ab2-b33b-eb832c4bb4c2).

    I did get a reply from the Motorola Customer Service rep (online, not the same as I got on the phone this morning) and she says that the info I need is proprietary, and I can't have it. Hummm, now i'm beginning to think it does go into FTM.

    I may have to go through GD to get the info instead of VFR direct to Moto.

    Just another thing guzz, based on that website, your v280 is capable of 900/1800/1900. If your taking it to alaska, your gonna have severe limitations in coverage since that phone doesnt pick up on the band (850) that is primarily used up there. T-mo operates on 1900 (which the phone is using), but up in Anchorage, t-mobile roams on the dobson (cellone) network which is just about all 850. See if you can get a phone that is compatible with all 4 bands (800/900/1800/1900) so that way you can do your tests accurately.

    Whay you can do is buy a cheap Moto V180, set it in 1900 only mode, then put it in field test. You can use it to test your areas where you plan to use the other phone.

    Although we'll use the phone for some voice transmissions, I believe the majority of the use will be to have the phone ignore voice and go straight into data mode in order to pass info. I'm wondering if we'll still have decent signal strength.

    Is there a site that will list specifically the cell tower frequencies for a given location and which network operates on those towers?

    Jay,

    Thanks for the suggestion; we may just have to do something like that. However, I also suspect that some of the people stationed up there could probably do that for us with their personal phones.

    I've never seen an operator make their frequency plan public information, so I highly doubt that.

    If you can see the network color code you can figure it out yourself. (Can you see the NCC with a regular phone in engineering mode?) For sure with "deeper" investigation tools you can (like TEMS).

    How about trying

    Menu Button
    *073887

    security code: 000000 (6 zeros)

    That's how I get into my test mode on my V262.

    Tried it, but no go.

    In fact, with this phone, when hitting the menu button followed by the *, it locks the keypad.

    Can you think of anything else it might be?

    Thanx,
