Operating frequencies

iDEN is designed, and licensed, to operate on individual frequencies that may not be contiguous. iDEN operates on 25 kHz channels, but only occupies 20 kHz in order to provide interference protection via guard bands. By comparison, TDMA Cellular (IS-54 and IS-136) is licensed in blocks of 30 kHz channels, but each emission occupies 40 kHz, and is capable of serving the same number of subscribers per channel as iDEN. iDEN uses frequency-division duplexing to separate transmit and receive signals, with transmit and receive bands separated by 39MHz, 45MHz, or 48MHz depending on the frequency band being used [1]. IS-54 and IS-136 are second-generation (2G) mobile phone systems, known as Digital AMPS (D-AMPS). ... IS-54 and IS-136 are second-generation (2G) mobile phone systems, known as Digital AMPS (D-AMPS). ... This article or section does not cite its references or sources. ...


iDEN supports either three or six interconnect users (phone users) per channel, and either six or twelve dispatch users (push-to-talk users) per channel, using time division multiple access. The transmit and receive time slots assigned to each user are deliberately offset in time so that a single user never needs to transmit and receive at the same time. This eliminates the need for a duplexer at the mobile, since time-division duplexing of RF section usage can be performed. Time division multiple access (TDMA) is a channel access method for shared medium (usually radio) networks. ... 1) A duplexer is a device that combines two or more signals onto a common channel or medium to increase its transmission efficiency. ...

Hardware

The first ever iDEN handset was Motorola's L3000, which was released in 1994. Most modern iDEN handsets use SIM cards, just like GSM and compatible with GSM handsets. Early iDEN models such as the i1000plus stored all subscriber information inside the handset itself, requiring the data to be downloaded and transferred should the subscriber want to switch handsets. Newer handsets using SIM technology make upgrading or changing handsets as easy as swapping the SIM card. Three different sized SIM cards exist, "Condor" SIMs are used with the two-digit models (i95cl, for example) using a SIM with less memory than the three-digit models (i730, i860). "Falcon" SIMS are used in the three-digit phones, (i530, i710) and will read the smaller SIM for backward compatibility, but some advanced features such as extra contact information and possibly GPS reception is disabled. There is also the "Falcon 128" SIM, which is the same as the original "Falcon", but doubled in memory size, which is used on new 3 digit phones (i560, i930).

Operators

In the United States of America there are two large public iDEN service providers: Sprint Nextel and SouthernLINC Wireless, and several small public and private iDEN service providers. Numerous private systems exist, including one run by ARINC, covering all major airports. Countries which have operating iDEN networks include Canada, Argentina, Peru, Mexico, Brazil, Jordan, Chile, Israel, Philippines, Singapore, Saudi Arabia, Japan, El Salvador and China. Full Roaming is available between Sprint/Nextel in the US, Telus (Canada), and NII (Mexico and S. American markets) Data/Voice/Radio. Voice only roaming in non NII markets.

Aeronautical Radio, Incorporated (ARINC) is the leading provider of transport communications and systems engineering solutions for five major industries (aviation, airports, defense, government and transportation) since 1929. ...


Motorola is committed to support of iDEN technology despite the Sprint buyout of Nextel and Sprint/Nextel's supposed eventual conversion to Sprint's CDMA system. Nextel has stated they will support iDEN until at least 2010, while other iDEN carriers have no foreseeable expiration date for their services. iDEN's Push-To-Talk feature is the fastest in the industry. Motorola Inc. ... General Information Generically (as a multiplexing scheme), code division multiple access (CDMA) is any use of any form of spread spectrum by multiple transmitters to send to the same receiver on the same frequency channel at the same time without harmful interference. ...

There is a smaller subset of the iDEN network called "Harmony Wireless Communications System", With Small System Release 5.0, it supports a maximum limit of 192 sites. With the introduction of Small System Release 6.1, it gains the ability to interface with a full iDEN system.
