airHaul 2 Nexus PRO™ User Guide
2.5. Device Operation Mode
This section explains the configurations possible in the different modes. With dual radios, the airHaul
2
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 airHaul
2
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 airHaul
2
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).
