    how do cell companies and the companies subcontracted to actually build the tower decide on the best location, is it satellitle calculated? or do they just go for places where the get complaints about there not being good service at? do they stand at potential locations and use equipment to check for ranges and capabilities? this stuff intrigues me:rolleyes:

    The specifics will depend on the actual carrier but the basics are the same throughout. When an initial buildout is done in a market the company identifies what ares it wants to cover first. Typically highways/airports and major business area. They'll look for prospective sites in those area once identifying good prospects they'll approach the landlord and try to arrange for field tests of that location. The areas for prospective sites are determined a lot by the local terrain, capacity needs and easy of buildout.

    Once the initial buildout is complete and they're working on filling in the gaps they work off a combination of modeling software, drive test results and customer complaints to work out which exact area should be covered on a higher priority than others.

    drive testing is done alot with specialized software that makes calls and that data is reviewed for signal levels, dropped calls, signal quality, etc.

    I could go on for hours/pages. Go to Andrew.com and look at Invertix. Also Google, Ericsson TEMS. Another site to check out is Actix.com

    Sites are based on Coverage and Capacity. We use propogation software with an estimated ERP (estimated Radio power). Alot of times we will try to Co-locate which is easier than a new build. Using drive test gear like Temms, Pro Scout, Data Pro Etc you can get a good idea of where towers are needed. I can tell just with a field test phone a idea of what is needed. You also have to take RSSI levels (tower signal level) in accout. The bars on the phone actually have a numeric signal level that you can only see on test gear.

    I looked back at my post and notice the same thing. I have years and years of RF and electronics training, but my grammer looks like I failed HS english.

    Oh well good thing I dont make a living on penmanship either.
