ABSTRACT:
Redundant wireless links in a meshed backhaul network may be used to improve quality of service on the backhaul network by confining knowledge of the duality to the attached network elements. Globally, an aggregate bandwidth of the redundant wireless links may be advertised to allow network level routing to treat the redundant links as a single logical link. At the link level, however, the network elements may differentiate between different types of traffic to provide preferential service to particular types of traffic. By using different physical links within the logical link for particular types of traffic, the quality of service for that type of traffic may be improved by not causing different types of traffic to compete for the same bandwidth. The redundant links may be interfaced using a tower network including a radio accessed router optionally powered using solar power, to isolate the tower network from ground equipment.
