YOZAN has become the latest WiMAX operator to join the WiMAX Spectrum Owners Alliance (WiSOA), and company chairman Sunao Takatori has been elected to serve as a WiSOA board member. YOZAN is the first to adopt and provide WiMAX services in Japan and is focused on providing services throughout areas of Tokyo, prior to expanding services to Osaka, Nagoya, and Kyoto. The company operates over 4.9GHz, which is a semi-licensed, registered spectrum in Japan.
YOZAN uses Airspan equipment to offer 802.16d fixed and nomadic services featuring the MicroMAX-SDR base station, which requires a “software only” upgrade to support 16e mobile WiMAX. On the customer premise equipment (CPE) front, YOZAN is co-developing with Airspan to produce a 16eUSB device that will become the first mobile WiMAX USB device. This device, which is designed to be fully compatible with the IEEE’s 802.16e-2005 standard and the WiMAX Forum Mobile WIMAX System Profile in Wave2, is designed to support MIMO, beam-forming smart antennas, idle and sleep modes and handover.
As a quad-band device that will operate in all key WiMAX frequency bands, including 2.3-2.4 GHz, 2.5-2.7 GHz, 3.3-3.7 GHz, and the 4.9-.5.4 GHz bands, it will allow users to have access to WiMAX networks almost wherever they are in the world. The device has participated in the Plugfests testing for interoperability of 16e products in the 1st and 2nd mobile WiMAX Plugfests.
