ST20G-N is a very excellent long-distance high-bandwidth microwave wireless transmission equipment, the measured data 20km can reach more than 200Mbps. The equipment power is 27dBm, the power supply voltage is 48V POE power supply (standard 802.11at specification), the working temperature supports -40℃~70℃, the shell design is IP66 standard, waterproof, dustproof, anti-oil, anti-dew, fog, the structure is designed with the internal and external pressure balance function, which improves the reliability of the product in the harsh environment.
Product Introduction:
ST20G-N wireless bridge software design uses TDMA+ polling outdoor video and data transmission wireless protocol, stronger anti-noise, can intelligently allocate time slots to each terminal device, eliminating the traditional 802.11 network there is a hidden node, low throughput problem. The device avoids conflicts in time slot allocation. This ensures that the device can poll each terminal and allocate a time gap to each terminal. In this way, possible conflicts can be avoided during transmission from terminals to access points. By checking the status of each client, using algorithms to check the activity of terminal devices and the type of services performed, the algorithm intelligently allocates time slots to each terminal to maximize efficiency, avoid wasting transmission time, and always maintain the best transmission efficiency. The special switch designed in the software kernel can effectively reduce the noise interference from the surrounding signal, effectively prevent or reduce the interference signal, and achieve better and more stable throughput and delay in the signal congestion area.
