Fujitsu Microelectronics America Inc., one of the first suppliers of a fixed WiMax transceiver chip, showed its first samples of the MB86K21 mobile WiMax chip at the Interop conference here.
In single-input, single-output mode, the chip can achieve throughput of 18.6 Mbits/second. Makoto Awaga, general manager of mobile solutions at Fujitsu Ltd., said the full MIMO capability would boost throughput to 45 Mbits/second.
Fujitsu used a 90-nm process with special clock-gating to keep power dissipating to 500 mW even in full MIMO mode, dropping to 10 mW in sleep mode.
Fujitsu showed several applications of its fixed mobile chip, including one from Kedah Electronics Engineering, which will use an earlier Fujitsu 802.16d chip for customer premises units and basestations.
