Nextel Begins Trials Of Wireless Network

The trial, which is free for selected consumers, is based on Nextel’s new “Wireless Broadband” network which uses technology based on FLASH-OFDM and offers secure, IP-based broadband access over a wireless connection.

FLASH-OFDM is a technology that originated in Bell Labs in early 1998. It is centered on FLASH (Fast Low-latency Access with Seamless Handoff) OFDM (Orthogonal Frequency Division Multiplexing), an innovative air interface technology designed for the delivery of advanced Internet services in the mobile environment. The technology is based on the OFDM airlink, a wireless access method that combines the attributes of its two predecessors – TDMA and CDMA – to address the unique demands posed by mobile users of broadband data and packetized voice applications. FLASH-OFDM enables the deployment of all-IP, packet-switched mobile broadband network.

The trial is scheduled to begin this month with approved customers receiving a wireless modem for their computer or a PC Card for a laptop. The trial provides these selected customers with free service for up to six months, the projected duration of the trial.

Anyone living in the Raliegh-Durham or Chapel Hill area that meets certain selection criteria able to participate in the trial – customers do not need to be an existing Nextel user.

At the end of the trial, participants will have the opportunity to join up for the service or cancel their service.

According to their Website, Nextel states that the Nextel Wireless Broadband service offers speeds comparable to DSL, Cable and wireline LANs and is 50 times faster than a 28 Kbps dial-up connection. “Our service is capable of realizing typical downlink speeds up to 1.5 Mbps, with occasional speeds, or bursts, as high as 3.0 Mbps, and typical uplink speeds up to 375 Kbps, with occasional speeds, or bursts, as high as 750 Kbps,” the site says.
