IDEN (integrated digital enhanced network)
Wireless technology developed by Motorola that combines the capabilities of a digital cellular telephone, two-way radio, alphanumeric pager and data/fax modem. iDEN can be operated in the 800MHz, 900MHz and 1.5GHz bands and is based on TDMA and GSM architectures. iDEN’s main differentiating feature is the built-in PTT function, such as that offered by Nextel.
