Description:

SF-5020CH is a high  performance, high stability of the 5 GHZ wireless bridge products. Inside the product integrates advanced 802.11 n wireless kernel and 2 * 2 MIMO high-gain double directional antenna polarization. the equipment has rich operating system and strong wireless communication, downward compatible with 802.11 a standard.Connects two remote nodes effectively,full bandwidth line-of-sight transmission distance can reach 8 km,provides wireless transmission quality of cable network quality.It mainly used in construction site area mine elevator and other special environments.

this product use IPoll (intelligent dynamic polling protocol),has strong anti-jamming capability, even in the interference seriously, can still support the stability of 64 users accessing to the base station equipment. the product is equipped  with double firmware images,ven if the power supply broke, upgrade failed when in the remote software upgrade process, the user still can normally restart the device.Solid made of polycarbonate plastic shell contains UV inhibitors, it guarantees the shell exposed under the sunlight outdoors for a long time but won't be damaged craze.

 the design of SF-5020CH meets the IP-65 protection class, vibration, temperature and humidity, salt fog and surge impact are in line with industry standards, with excellent reliability to ensure the industry leading level. the equipment is equipped with a grounding lug and POE power supply to prevent from lightning strikes.

the device supports WNMS management system, which is a free enterprise-class wireless network management system. Using a single software solution for network administrators to simplify a large number of equipment management and network monitoring tasks. the integrated network management system supports thousands of network nodes. A system can monitor and maintain multiple networks. Rich set of features can help you effectively diagnose network failures, visualize network management, automatically perform scheduled firmware upgrades, update device status, fault alerts, and collect statistical network data. Based on the Web system environment, support multi-user account management. Multiple administrators can manage different networks on the same server without having access to the devices of their respective networks.

SF-5020CH operating system is versatile and easy-to-use to ensure that a full range of hardware devices in the network deployment can easily complete the configuration.
