SDL530 networking application

    Long-distance two-way wireless data communication can be achieved using SDL530 module，Point-to-point two-way communication possible，Point-to-multipoint star networking can also be used for two-way communication. ，As well as relay and wireless ad hoc network Mesh methods(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，Each node is in the same wireless LAN，All access nodes communicate with the central node and share the wireless working bandwidth，The module will automatically distribute the system speed evenly。Data transmission in the direction from the central node to the access node is called downlink，Data transmission in the direction from the access node to the central node is called the uplink.。When communicating point-to-point or point-to-multipoint，Downlink and uplink share wireless operating 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，The IP camera should be connected to the access node。The module will automatically and dynamically adjust the wireless transmission rate according to the business data stream carried.，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，You can increase the wireless transmission distance by appropriately reducing the IP Camera video encoding bit rate.。
