Product Introduction:

ST52W-A is a new generation of 802.11ac 2x2 dual-band wireless access equipment, which can provide customers with stable outdoor wireless signal coverage and ensure that customers enjoy stable, high quality and convenient broadband services. The system has a built-in 17dBi 5GHz directional antenna, which can bridge or receive signals from remote wireless devices. The external 3dBi 2.4GHz omnidirectional antenna can cover wifi signals around the system. 5G transmission distance: 0~5km, 2.4G coverage range: 0~150m. The maximum power of the host can reach 27dBm, supporting the 802.11a/b/g/n/ac 2G/5G standard. The system power supply is Passive POE (48V POE). The maximum power consumption is 12W, and the average power consumption is no more than 9W. The operating temperature supports -40℃~65℃, and the shell design IP66 protection standard.

The software design uses TDMA+ polling outdoor video and data transmission wireless protocol, which is more anti-noise, and can intelligently allocate time slots to each terminal device, eliminating the problem of low throughput when there is a hidden node in the traditional 802.11 network. 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.
