SDL532 networking application

    Using SDL532 module can realize long-distance two-way wireless data communication，Point-to-point two-way communication possible，It can also communicate bidirectionally in point-to-multipoint star network ，And relay and wireless ad hoc network Mesh mode(custom firmware)two-way communication。During point-to-multipoint communication，If communication is required between two access nodes, it must be relayed through the central node，All nodes are in the same WLAN，All access nodes communicate with the central node to share wireless working bandwidth，The module will automatically distribute the system speed evenly。The data transmission from the central node to the access node is called downlink，The data transmission from the access node to the central node is called uplink。During point-to-point or point-to-multipoint communication，The downlink and uplink share wireless working bandwidth。When the module is shipped，The default setting is the ratio of uplink rate to downlink rate=4:1。therefore，If the module is used to transmit IP Camera video data，IP camera should be connected to the access node。The module will automatically and dynamically adjust the wireless transmission rate according to the carried business data stream，When the amount of business data carried is smaller，Under the same conditions, the transmission distance will be farther。therefore，When using the device to transmit IP Camera video data，The wireless transmission distance can be increased by appropriately reducing the IP Camera video encoding bit rate。
