Future broadband networks need to provide high capacity at low cost with increased revenue through enhanced services. WiMAX came up as one of the leading technologies, however, the 2.3 GHz and 2.5 GHz frequency bands allocated create two serious coexistence issues with the adjacent 2.4 GHz ISM band. First problem is to address radio interfaces that are located on two independent platforms and still possess the potential for mutual interference owing to close proximity to each other. The Adaptive Frame Reservation Scheme presented here extends the CTS frame reservation signaling defined in 802.11 specifications to a demand based and adaptive scheme. Second issue is to address the coexistence problem in multi-radio platforms where two or more radios are co-located, creating an even worse interference scenario. This can be managed by hardware signaling that can be made available between radio interfaces through OS control. The development of a smart Co-located Coexistence Controller is explored which continuously receives transmission, reception and sleep requests from attached interfaces and in return grant permissions.

自适应帧保留方案和朴素持久状态共存共存控制器的开发

未来的宽带网络需要以低成本提供高容量,并通过增强服务增加收入。WiMAX 作为领先技术之一出现,然而,分配的 2.3 GHz 和 2.5 GHz 频段与相邻的 2.4 GHz ISM 频段产生了两个严重的共存问题。第一个问题是解决位于两个独立平台上但由于彼此靠近而仍具有相互干扰潜力的无线电接口。此处介绍的自适应帧预留方案将 802.11 规范中定义的 CTS 帧预留信令扩展为基于需求的自适应方案。第二个问题是解决多无线电平台中的共存问题,其中两个或更多无线电位于同一位置,从而造成更严重的干扰情况。这可以通过硬件信令进行管理,硬件信令可以通过操作系统控制在无线电接口之间提供。探索了智能共存共存控制器的开发,该控制器不断接收来自附加接口的传输、接收和睡眠请求,并作为回报授予权限。
