The solution adopts carrier-grade access points with extraordinary signal capability and high power guarantees perfect signal strength (-75dBm) even after penetrating two brick walls. The system has been passeesting which is able to maintain perfect performance under harsh environments.


All access points support multiple SSIDs. It can simultaneously broadcast both customer and work SSIDs. To separate operation network from office network, customer and work SSIDs are bounded to different VLANs. They can also supports security features of black and white list access control and rogue access point detection.


Our solution adopts WEB authentication which is an important security control method for the administrator. After wireless client associates access point, Wireless LAN Controller’s internal portal server will push authentication WEB page to it. First input username and password on the portal page, user will be allowed to access network after being successfully authenticated by internal radius server.
