Motorola originally referred to the platform as wiDEN, choosing to capitalize only the letters representing " Digital Enhanced Network ," as it had with iDEN.

There are currently five companies in Israel which offer cellular communication service ( with network technology used listed in ): Pelephone and Universal Mobile Telecommunications System | UMTS, Cellcom and UMTS, Partner Communications ( Orange ) and UMTS, Mirs ( HOT Mobile ) and Integrated Digital Enhanced Network | iDEN, and Golan Telecom.

Integrated Digital Enhanced Network ( iDEN ) is a mobile telecommunications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone.

The first commercial iDEN handset was Motorola's L3000, which was released in 1994.

Countries which have operating iDEN networks include Canada, Argentina, Peru, Mexico, Brazil, Jordan, Chile, Israel, Philippines, Singapore, Saudi Arabia, Japan, El Salvador, China and most recently India and Guatemala.

Sprint / Nextel has stated they will support iDEN until June 2013 and Sprint has maintained their iDEN holdings with the purchase of the Sprint CDMA affiliate network, iPCS, for $ 426 million, which Sprint was repeatedly engaged in lawsuits over non-compete agreement violations stemming from the 2005 purchase of Nextel and the later purchase of Nextel Partners.

# GSM ( Global System for Mobile Carriers ) is one of the various cellular technologies which include TDMA, CDMA, iDEN and others.

Boost Mobile's Monthly Unlimited Plan ( which differs from their previous UNLTD plans ), was also offered nationwide for iDEN handsets as of January 22, 2009 and CDMA as of January 2010.

Telus plans to launch a push to talk service over LTE, which will eventually replace Telus ' iDEN Network, though no timeline has been announced for these changes.

Most mobile phone networks are digital and use the GSM, CDMA or iDEN standard which operate at various radio frequencies.

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

WiDEN has not been active on the NEXTEL National Network since October 2005 when rebanding efforts in the 800 MHz band began in a Sprint effort to utilize those data channels as a way to handle more cellular phone call traffic on the NEXTEL iDEN network.

The interconnect-side of the iDEN network uses GSM signalling for call set-up and mobility management, with the Abis protocol stack modified to support iDEN's additional features.

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.

iDEN uses frequency-division duplexing to transmit and receive signals separately, with transmit and receive bands separated by 39 MHz, 45 MHz, or 48 MHz depending on the frequency band being used.

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 network through, at least, 31 December 2010.

The unexpected surge in popularity for the service caused significant strain on the Nextel iDEN networkas many customers reported long and sometimes week-long delays in receiving text messages.

Boost Mobile's walkie-talkie service ( only on iDEN handsets ) is compatible with " Nextel Direct Connect " in the United States, Mexico, Brazil, Argentina and Peru and with Telus Mobility in Canada.

Includes nationwide unlimited talk, text / media messaging, web access, instant messaging, email, 411 directory assistance and Walkie-Talkie ( on iDEN series phones only ).

They currently have three different networks based on four different technologies: CDMA, HSPA + and LTE on its mainstream networks, plus iDEN via its Mike division.

Telus Mobility also sells services on an Integrated Digital Enhanced Network ( iDEN ) via its Mike brand.

TDMA is used in the digital 2G cellular systems such as Global System for Mobile Communications ( GSM ), IS-136, Personal Digital Cellular ( PDC ) and iDEN, and in the Digital Enhanced Cordless Telecommunications ( DECT ) standard for portable phones.

By comparison, TDMA Cellular ( Digital AMPS ) 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.

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.

There is a smaller subset of the iDEN network called " Harmony Wireless Communications System ".

On the bottom line, it is more of a North American phenomenon due to existence of iDEN and other networks.

The former is closer to the original pronunciation of iDEN, as " eye " and " den ".

The International Mobile Equipment Identity or IMEI () is a number, usually unique, to identify 3GPP ( i. e., GSM, UMTS and LTE ) and iDEN mobile phones, as well as some satellite phones.

A Mobile Country Code ( MCC ) is part of the International Mobile Subscriber Identity ( IMSI ) number, used in combination with a Mobile Network Code ( MNC ) ( also known as a " MCC / MNC tuple ") to uniquely identify a mobile phone operator / carrier using the GSM / LTE, CDMA, iDEN, TETRA and UMTS public land mobile networks and some satellite mobile networks.

The Motorola i920 / i930 is Motorola's first wave of iDEN Protocol-based smartphones.

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, it would be redundant to keep upgrading the iDEN data network.

The iDEN project originally began as MIRS ( Motorola Integrated Radio System ) in early 1991.

Nextel Communications introduced mobile push-to-talk in August 1993 using iDEN.

Wireless telephony services are provided by ATT Mobile, formerly Cingular, ( GSM850 / GSM1900 ), T-Mobile ( GSM1900 ), AllTel, formerly First Cellular of Southern Illinois, ( now CDMA-only although legacy GSM850 service still operates ), Verizon ( CDMA ), Nextel Partners ( iDEN ), and Sprint PCS ( CDMA ).

iDEN places more users in a given spectral space, compared to analog cellular and two-way radio systems, by using speech compression and time division multiple access ( TDMA ).

Examples of digital communication are APCO Project 25, a standard for digital public safety radios, Nextel's iDEN, Motorola's MOTOTRBO DMR, Hytera's DMR, and NXDN implemented by Icom as IDAS and by Kenwood as NEXEDGE.

Boost would still use the previous Nextel iDEN infrastructure for its service, but in 2006, it began to offer a new Unlimited by Boost Mobile service in select markets using Sprint's CDMA network, offering unlimited talk, text, and internet.

When Telus Communications acquired Clearnet Communications in 1999, this included a Integrated Digital Enhanced Network ( iDEN ) branded as Mike by Clearnet.
