iDEN

iDEN is a TDMA based digital mobile network system developed by Motorola and used most notably by Nextel in the United States. Its main draw, from the consumer's viewpoint, is its low-latency Push-To-Talk system that emulates the use of walkie-talkies on mobile phones. The system's future is uncertain, however, since US carrier Sprint bought Nextel and stated that it plans on transitioning all Nextel clients to its CDMA based network. Dual-mode iDEN/CDMA handsets are already available to Sprint customers.
Also known as: "Integrated Digital Enhanced Network"
