A fixed wireless access network provides for high-frequency data links between aggregation nodes and endpoint nodes. The system further provides for lower frequency wireless data links, which have carrier frequencies less than high-frequency wireless data links. These lower frequency links provide for auxiliary communications between the aggregation nodes and one or more endpoint nodes. During normal operation, the nodes exchange packet data via the high-frequency data links. However, when impairment of the high-frequency data links is detected, the nodes direct the packet data over the low-frequency data links instead until the high-frequency data links are no longer impaired.

A method includes receiving packets of data from an external network and receiving location information over a wireless communication link from a wireless communication device located inside a building. The location information indicates a relative location of the wireless communication device. The method also includes executing beam forming with the wireless communication device based on the received location information to form a communication beam directed toward the wireless communication device. The method also includes transmitting the communication beam over the wireless communication link from the external network interface unit to the wireless communication device, the communication beam containing the data packets.
