Nokia is broadening its wireless offerings, with plans to sell WiMAX phones by 2008.
That would certainly be an advancement in the popular wide-range technology, which currently requires stationary connections. Researchers are working on a mobile version, with one is expected by the end of this year: this gives plenty of time for Nokia to get its hands on the technology and start packing it into their phones.
Nokia and the other major wireless carriers like the flexibility of Wi-Fi and WiMAX in their phones, especially to take some data-carrying pressure off existing 3G networks. WiMAX improves on Wi-Fi by offering a wider range of access.
