Introduction
Integrated Digiatal Enhanced Network (iDEN) is a mobile telecommunications technology,developed by Motorola Company.
Provides its users the benefits of truncked radio and a cellular telephone.
iDEN is desinged to give the mobile user quick access to information without having to carry around several devices.
Text messaging,Picture messaging & Voice Communication are supported by iDEN.
iDEN operates on 25 kHz channels.
It supports either THREE or SIX interconnect user per channel,and either SIX or TWELVE dispatch users per channel.
iDEN handsets use SIM Cards,just like GSM and compatible with GSM handsets.
In the United States of America there are two large public iDEN service provider :-
1. Sprint/Nextel
2. SouthernLINC Wireless

iDEN Useful Terms
Analog
In telecommunications, an analog signal is one in which a base carrier's alternating current frequency is modified in some way.
An analog signal can be represented as a series of sine waves.
Cellular Phones
Cellular telephone is a type of short-wave analog or digital telecommunication in which a subscriber has a wireless connection from a mobile telephone to a relatively nearby transmitter.
iDEN Useful Terms
Digital
Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive.
Positive is expressed or represented by the number 1 and non-positive by the number 0.
Wireless
Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path.
What is iDEN Technology?
iDEN stands for integrated Digital Enhanced Network:
Five integrated services in one single device give users more choices on how to communicate.
All digital technology provides a solid network platform for ongoing system enhancements, so users always have the benefit of the newest technology.
By having access to an enhanced multi-site network, users have wider area coverage where they do business.
A true wireless network approach provides two-way radio customers with many advantages not found on older Specialized Mobile Radio (SMR) systems.
iDEN handsets streamline communications by providing a five-in-one solution that combines the capabilities of:
1.a digital wireless telephone,
2.nationwide and international two-way radio,
3.packet data for Internet access,
4.two-way e-mail and text messaging, and
5.wireless modem capabilities.
How does the Technology Work?
Motorola developed its proprietary iDEN technology in the early 1990’s as a way to consolidate unused spectrum.
iDEN technology utilizes highly spectrum-efficient radio transceivers to digitize and process high volumes of voice and data through a single channel.
It is based on trunking systems and uses TDMA (time division multiple access) technology for multiple access.
In addition, iDEN technology uses packet data, allowing for faster transmission of information, maximizing channel capacity and maintaining a constant Internet connection.
For users, this translates to high voice quality, lower latency, dependable communications and literally instant access.
How do Users benefit?
Multiple wireless services in one handset provide mobile workers with fast, flexible and cost-effective communication capabilities that can increase productivity,
improve efficiency and minimize costs by allowing them to carry a single device.
The two-way radio service allows users to easily and instantly communicate with one or many people at the push of a button, from coast to coast and to Hawaii, Canada, Mexico, Peru, Brazil, and Argentina.
