Technology
iDEN

iDEN - iDEN (Integrated Digital Enhanced Network) is a wireless network standard developed by Motorola and used by Nextel Wireless. It operates at 800Mhz, 900Mhz and 1500Mhz frequency bands and it is a mixture of TDMA (Time Division Multiple Access) and GSM arhitecture. It allows the use of one mobile device as a digital phone, pager, two-way radio and fax/modem.

 800, 900 MHz 
AMPS

AMPS - Advanced mobile phone standard. Analogue standard used widely in North America.

800 MHz  
TDMA

TDMA - Time Division Multiple Access. A multiplexing technology used with satellites and cellular phones, in which multiple channels of data are interleaved (each signal is assigned to a different time interval, and the signals are transmitted by taking turns). . For cellular, TDMA triples the capacity of the original analog method. The GSM cellular system is also based on TDMA, but GSM defines the entire network, not just the air interface.

Positioning

Positioning - This field shows the positioning systems supported by the device. There are three main types: GPS, A-GPS and GLONASS. GPS - This is one of the most widespread global positioning technologies, developed and maintained by the U.S. government. It uses satellites in order to detect your location. Works best in clear weather. A-GPS - A-GPS stands for Assisted GPS and is the industry standard for positioning and navigation. “Assisted” means that it can use local wireless networks, in addition to satellites, for quicker and more precise localization. GLONASS - GLONASS is a global positioning system, developed by the Russian Federation. It’s very similar to GPS, but isn’t so popular in cell phones.
