Wideband Integrated Dispatch Enhanced Network, or WiDEN, is a software upgrade developed by Motorola for its iDEN enhanced specialized mobile radio (or ESMR) wireless telephony protocol.

WiDEN History

iDEN, the platform which WiDEN upgrades, and the protocol on which it is based, was originally introduced by Motorola in 1993, and launched as a commercial network by Nextel in the United States in September 1996.

WiDEN was originally anticipated to be a major stepping stone for United States wireless telephone provider Nextel Communications and its affiliate, Nextel Partners. However, with the December 2004 announcement of the proposed Sprint Nextel merger, it has been speculated that the Nextel iDEN network will be quickly abandoned in favor of Sprint's CDMA network. Although a complete roadmap of the merger's impact on the combined company's wireless networks has not been released, Nextel and Motorola have agreed to continue to maintain and expand the iDEN (and WiDEN) network through, at least, 31 December 2010. Sprint Nextel Corporation (NYSE: S) is one of the largest telecommunications companies in the world. ... 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. ...

WiDEN Subscriber Units

The first WiDEN-compatible device to be released was the Motorola iM240 PCMCIA card which allows raw data speeds up to 60 kbit/s. The first WiDEN-compatible telephones are the Motorola i850 and i760, which were released mid-summer 2005. The recent i850/i760 Software Upgrade enables WiDEN on both of these phones. The commercial launch of WiDEN will come with the release of the Motorola i870 which was released on 31 October 2005. As of Early 2006, WiDEN is available in most places on Nextel's National Network. Update: Since the Sprint Nextel merger the company determined that because Sprint's CDMA network was already 3G and going to EVDO (broadband speeds) and then EVDO Rev A (T-1 speeds) it would be redundant to keep upgrading the IDEN data network. Portable Computer Cards (PC cards) are interchangeable peripherals designed to be inserted into laptop computers in order to enable extra hardware functions. ... The Motorola i870 is a clam-style cellular telephone designed for use with iDEN Networks. ...

iDEN Networks

26 commercial iDEN networks exist in 21 countries.

Capitalization and Pronunciation

Motorola originally referred to the platform as wiDEN, choosing to capitalize only the letters representing "Dispatch Enhanced Network," as it had with iDEN. However, subsequent promotion from Motorola and Nextel has indicated that the preferred capitalization is WiDEN.

The term has been pronounced, commonly, as a close combination to the words "why" and "den", or simply as the word "widen". The former is closer to the original pronunciation of iDEN, as "eye" and "den".
