Fujitsu Improves WiMax Efficiency

KDDI has announced early results from their joint R&D with Fujitsu Labs on energy and cost saving measures for future WiMax base stations. Nitride gallium HEMT, a stronger semiconductor material than conventional silicon, was used in a field experiment which achieved electric power output of 25W and operation frequency 2.5GHz. According to the statement they recorded electric power efficiency of the transmission amplifier at 30% improvement over previous attempts.

ITU to make WiMAX a 3G standard

WiMAX Day, a newsletter published by the WiMAX Spectrum Owners Alliance, reported the ITU Working Party 8F met in Cameroon at the end of January to look at IMT-2000 and systems beyond IMT-2000. Such a move would bring considerable benefits by allowing WiMAX to operate in globally allocated frequency bands, enable global roaming and reduce equipment costs.
