外接PA提高发射功率
DLB模块自身最大发射功率为25±2dBm，矽海达同时提供配套的功率放大模块(2W/5W/10W)以提高发射功率，满足不同场景不同距离的应用需求。下图是DLB模块与配套功率放大模块的对接示意图。
DLB组网应用
采用DLB模块可实现远距离双向无线数据通信，可以点对点双向通信，也可以点对多点星型组网方式双向通信 ，以及中继与无线自组网Mesh方式(定制固件)双向通信。在点对多点通信时，如果两个接入节点之间需要通信必须通过中心节点中转，各节点在同一个无线局域网内，所有接入节点与中心节点通信共享无线工作带宽，模块会自动平均分配系统速率。中心节点到接入节点方向的数据传输称为下行链路，接入节点到中心节点方向的数据传输称为上行链路。在点对点或点对多点通信时，下行链路与上行链路共享无线工作带宽。模块出货时，默认设置为上行速率与下行速率配比=4:1。因此，如果利用模块传输IP Camera视频数据时，IP camera应接到接入节点。模块会根据所承载的业务数据码流进行无线传输速率的自动动态调节，当所承载的业务数据量越小，同等条件下传输距离会越远。因此，当利用设备传输IP Camera视频数据时，可通过设置适当减小IP Camera视频编码码率来提升无线传输距离。
