The initial concept for NLOS Wireless Backhaul revolved around small cell sites. However, the Taqua NLOS Backhaul System can be used to transport Ethernet traffic to and from any location.

For example, if a carrier wants to provide a fixed Ethernet service to a small building but cannot financial justify the cost of installing fiber then, NLOS Backhaul can be used. The following diagram shows a situation where a fixed Ethernet service is extended to 3 buildings with NLOS Backhaul:

Remember that Taqua's NLOS Backhaul is really a point-to-multipoint wireless Ethernet transport system.   Because Ethernet is the fundamental Layer 2 transport technology, Taqua's NLOS Backhaul system can transport data from any 3G or 4G small cell site on the market (since they all have Ethernet interfaces), a WiFi access point and a even fixed Ethernet network connection.

This fixed Ethernet NLOS backhaul application is probably most valuable when a Line of Sight link is not available.  After all, microwave links have been used for decades to provide similar enterprise last mile connectivity.
 
Ultimately, these NLOS links to buildings could be replaced with fiber when the business case and traffic load from the building justifies the cost of a installing a fiber cable.  

The key value of NLOS wireless backhaul for this last mile application is its flexibility and speed of deployment.   Implementing a Taqua NLOS backhaul link will allow a carrier to quickly seize a competitive opportunity to win a new Ethernet fixed service from an enterprise or building owner until a fiber connection can be financially justified.
