GSM (gprs, edge, 3G)
A GSM fax machine is that a fax machine that connects to the phone network through GSM (Global System for Mobile) (aka cell phone technology).
The technology that is need to track a cell phone is one it is the cell phone that count on a GSM. The GSM allowed the cellphone to have GPS. If the cellphone have GPS, it can be tracked.
yes,any mobile 2day operates on dtmf tech. and sometimes call it as touchtone tech.,.

Hiphones run on GSM technology, which is not compatible with the technology used by Boostmobile. So those phones would not work on Boostmobile. Hiphones would only work on GSM carriers.
DTMF means Dual Tone Multi Frequency this is every key on your phone key pad, each key generates two tones over top of each other hence the Dual Tone of DTMF. This also applied to touch tone telephones that are hardwired in homes and businesses, they also use DTMF keying.
Dropped and Missed CallsAccording to Cellular News, call quality problems, including dropped calls and missed calls are common problems with GSM technology. These problems result directly from the technology in use. GSM technology cannot accommodate as many callers on a single cell tower as the more modern CDMA technology. This means that callers in areas where there are not a preponderance of cell towers may find that the call problems on GSM will be more common.Security IssuesZDNet UK reports that GSM has a serious security flaw, demonstrated by a hacker who was able to intercept phone calls from a number of GSM-based cellular phones. The problem is based directly on the technology according to this hacker and his solution was to "turn off" the GSM technology (only the older 2G technology though) that is commonly used by people all over the world. The problem is largely mitigated however by the use of the more modern 3G technology that is commonly used (as of November, 2010) on many GSM phones.EfficiencyAnother problem with GSM is a network problem rather than a consumer problem, though it is a consumer problem for those who don't want to see a proliferation of cellular towers. As previously noted, GSM technology can handle fewer callers on a single cellular tower. Therefore, networks who work with GSM must find ever more areas to built GSM cellular towers, causing them to have problems with costs and locations. By the same token, some consumers who prefer not to see a proliferation of cellular towers consider this a problem because the cellular towers must be placed in more and more urban areas, potentially spreading more radiation and causing what some consider a blight on the landscape.
