2.5. Device Operation Mode

This section explains the configurations possible in the different modes. With dual radios, the airHaul2 Nexus PRO allows for maximum operation flexibility.

2.5.1 Repeater Mode Configuration

Normally, to extend the WLAN coverage of an access point, a repeater site with 2 single radio backhauls will be used in a Root and Remote combination. This results in a degradation of the link efficiency which could be due to several reasons: a single link with larger spacing gives lower bandwidth, the Remote might not be in line of sight, etc.

However, with the dual radio airHaul2 Nexus PRO configured in Repeater Mode, it is possible to extend WLAN coverage while still maintaining a higher bandwidth.

Figure 2-7 Repeater Mode

In the above diagram, we see that the airHaul2 Nexus PRO configured in Root Bridge Mode is servicing an Internet backbone. One radio (Radio A) is configured as Root and the other radio (Radio

B)is configured as a Remote Bridge or Remote Router/NAT. In such a scenario, the backhaul link can span up to 50 miles (80 km).
