The title of this article is incorrect because of technical limitations. The correct title is iDEN.

iDEN (Integrated Digital Enhanced Network) is a mobile communications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone. Nextel is the largest US retailer of iDEN services. iDEN places more users in a given spectral space, compared to analog cellular systems, by using time division multiple access (TDMA).

iDEN is available in many countries through Nextel International (and possibly other carriers). Some information suggests that Nextel in europe utilizes iDEN over GSM, but this is not confirmed. Nextel International allows directo-connection (PTT operation) to work overseas - Brazilian nextel users in Brazil can PTT with users roaming in the US, Argentina, Chile, and other countries!!!

Data (such as paging, text messaging and picture messaging) and voice communications are supported by iDEN.

In order to provide high data rates for packet data, Nextel started to develop a 2.5G technology called WiDEN. A packet is the fundamental unit of information carriage in all modern computer networks. ... 2. ... Wideband Integrated Dispatch Enhanced Network, or WiDEN, is a software upgrade developed by Motorola for its iDEN enhanced specialised mobile radio (or ESMR) wireless telephony protocol. ...

WiDEN was a planned expansion on the iDEN system, where instead of using a normal 25 kHz channel for packet data, it would encompass 4 carriers (100 kHz) into one channel. This would have allowed download speeds of 96 kbit/s, which is comparable to the average CDMA2000 speeds from American competitors Sprint and Verizon.
