Nextel Communications is at least a year away from launching national mobile broadband services, the company confirmed this week, making it late to the party compared to rivals such as Verizon Wireless. Nextel spokesman Aaron Radelet on Tuesday said <A HREF="http://news.com.com/2100-1039_3-5471329.html">WiMax is not in the running</A> for the carrier's planned broadband service, citing a lack of appropriate spectrum licenses. Nextel is licensed to provide wireless services in the 1.9Mhz band, whereas WiMax currently uses the 2.5Mhz band.
