What is iDEN

iDEN (Integrated Dispatch Enhanced Network) is a TDMA trunked radio system which is used for mobile telephony. iDEN uses Motorola's VSELP (Vector Sum Excited Linear Prediction) system for voice compression, which enables iDEN to fit 6 voice conversations into one 25Khz channel. iDEN (Integrated Dispatch Enhanced Network) was developed by Nextel and Motorola. iDEN is sometimes referred to as a ESMR (Enhanced Specialized Mobile Radio) System. iDEN Network Operators Nextel operates an iDEN network in the United States.
