The Integrated Digital Enhanced Network (iDEN) is a proprietary mobile communications technology from Motorola. It is a TDMA based digital wireless standard. It operates in the 800 MHz, 900MHz, and 1.5 GHz bands. It combines the capabilities of a digital cellular telephone and a two-way radio known as push-to-talk (PTT).

Motorola’s iDEN® technology phones support many other features including Bluetooth, location-based services, MOTOTalk and support for expandable memory (Micro SD. Sprint Nextel is the largest U.S. retailer of iDEN services.

Newer iDEN phones use a SIM card that is compatible with GSM phones for overseas roaming but iDEN is a very different standard from GSM. iDEN phones are not compatible with GSM networks and GSM phones are not compatible with iDEN networks.

History

iDEN was invented by Motorola who is presently the primary manufacturer of iDEN devices.

Nextel has started to develop a 2.5G technology called WiDEN in order to provide high data rates for packet data. WiDEN is a planned expansion on the iDEN system, where instead of using a normal 25 kHz channel for packet data, it will encompass 4 carriers (100 kHz) into one channel. This would allow download speeds of 96 kbit/s, which is comparable to the average CDMA2000 1x speeds from American competitors Sprint and Verizon Wireless.
