The Integrated Digital Enhanced Network (iDEN) is a proprietary mobile communications technology from Motorola. It is a TDMA based digital wireless standard that 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.


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 (an expansion of iDEN) that includes four carriers (100kHz) into one channel. This results in a much higher download speed of 96 kbit/s.


Software for acquiring a iDEN data includes:
