It has over 11 million U.S. subscribers, and as of 2003, claims to serve "198 of the top 200 U.S. markets."
The company works closely with a single vendor, Motorola, on both equipment and standards. The close relationship has yielded the iDEN protocol which uses time division multiple access (TDMA) technology. Some of Nextel's unique features include its push-to-talk feature, which simulates the half-duplex operation of a two-way radio. A downside of this sole-source and proprietary standard has been a lack of innovation in handset size and weight, compared to mobile telephony industry trends.
Nextel has a huge advantage in the push to talk industry, though in 2003 Verizon Wireless has launched a push to talk feature and other cell phone providers have announced plans to launch similar half-duplex features. Nextel and Verizon are currently in a legal battle over Verizon's push to talk feature.
On November 17th, 2003, Sprint announced that they were launching a push to talk feature. Two Sanyo phones will be used for Sprint's PTT service [1]
Nextel announced plans in 2003 for its next generation, or 3G offerings. It will use an extension to iDEN called WiDEN, also from Motorola.
