Publication Date:  2015-06-30 Views:  1228 Downloads:  0
Issue Description
Which NPE Scenarios usually occur in WLAN ?what should be noticed in that scenarios?

1.Country Wi-Fi Coverage:Rural country coverage, The wireless links between APs and NPEs can be using for data transmitting. Home gateway or wireless router can be de deployed in the location of NPE.

2.Video Surveillance :The cameras connecting to the NPE

1. The maximum NPE number in this mode P2MP is 32.
2. When the backhaul transmission distance is within 1 km, a network bridge can transmit data to up to 32 network bridges.
3. When using this P2MP mode, the NPEs must be located within the main lob of the root antenna.
4. When the backhaul transmission distance is longer than 5 km,choosing the P2P mode and installing a parabolic reflector dish for NPE is recommended.And for AP, a small-angle directional antenna is the best choice. Because high gain and small angle which can effectively reduce interference to other Aps
5. If there is an obstacle between AP and NPEs, using this architecture to avoid the obstacle.
6. When the backhaul distance greater than 3km,  must pay attention to the line of sight on the Fresnel Zone.
