  • WiMAX is a wireless broadband technology that is a new air interface standard for microwave and millimeter wave bands. As a wireless metropolitan area network technology, WiMAX is able to provide higher transmission rates for both fixed and mobile users over a larger coverage area. One view is that WiMAX can be used as an important support means for 3G and 3G evolution of wireless metropolitan area networks and multi-point base station interconnection. In the future, WiMAX may merge 3G's mature operation system and make up for the lack of 3G in data. As the WiMAX industry chain matures, many equipment vendors are beginning to develop WiMAX-related products, including a variety of end products. WiMAX CPE is one of them.
  • WiMAX CPE As a user terminal device, WiMAX CPE provides users with high-speed wireless data services and voice services, and can customize special services by users, and also supports home gateway functions. Since the existing WiMAX module only supports wireless data services, the separate modules do not support the home gateway. Therefore, in order to meet the above requirements, an independent CPU must be added to implement the voice service and the gateway function.
