Nextel SummaryNEXTEL is the former wireless brand of NEXTEL Communications, and it operates on Motorola's iDEN protocol which uses time division multiple access (TDMA) based technology. Unlike other cellular operators, Nextel utilizes the specialized mobile radio band (SMR) and was one of the first operators in the United States to offer nationwide digital-cellular radio coverage. The Nextel brand has over 18.5 million U.S. subscribers, and is particularly popular in the southern United States. Some of Nextel's special features include its push to talk (PTT) feature, Direct Connect, which simulates the half-duplex operation of a two-way radio, and is available nation wide (providing that both the sender and reciever are both in a service area) as well as limited global direct connect availability. Nextel also offers GPS integration in current handsets. However, there are several downsides related to using this proprietary Motorola technology standard. It has been suggested there has been a lack of innovation in handset size, weight, and function compared to cellular industry trends, though many believe this has begun to change as result of the Sprint Nextel merger. Since very few carriers have adopted iDEN in the USA and Nextel is the only national operator of iDEN, roaming is extremely limited in the USA. Nextel does have iDEN roaming agreements with rural carriers like Airtel, Extend America, and SouthernLINC Wireless . Along with operators |
