High Performance 5.8GHz Outdoor Wireless Bridge
ST515N is a high-performance, multi-purpose 5.8GHz wireless bridge product with Qualcomm core solution. High TX power, high-quality hardware and a built-in 15dBi directional antenna make it an ideal choice for medium and short-range transmissions. It is recommended to be used in the last 3 kilometers , and the longest transmission distance can reach 5 kilometers. It is suitable for various video surveillance scenarios such as agriculture, forestry, industry, commerce, transportation and docks .

IPoll 3 intelligent polling wireless protocol
The wireless protocol based on TDMA technology can not only eliminate transmission congestion and self-interference generated in outdoor long-distance point-to-multipoint transmission , but also with the latest intelligent polling mechanism it groups the connected stations according to their activity.

Multicast enhancement
The multicast optimization function allows multicast traffic to be sent only to terminals in need, avoiding the waste of network resources.

Advanced QoS
- QoS in iPoll 3 supports transmitting pre-marked data according to priority.
- QoS (L2/L3 or DSCP/COS) - supports different priority traffic types (must be implemented with switches that support corresponding functional mechanisms)
- Providing 4 queue priorities for different services (best effort , background , video , voice)
- Strict policy based
- Supports multiple services (data , voice , video, etc.)

Professional graphical user interface
The device management GUI is based on HTML 5 technology, which is responsive, easy to configure, and adaptable to computer browsers and mobile browsers.
