Abstract
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 wireless access system, the system comprising:
- endpoint nodes installed at premises;
- and
- an aggregation node for communicating with the endpoint nodes, the aggregation node comprising a phased array antenna system for transmitting information to and receiving information from the endpoint nodes via high-frequency wireless data links, and one or more auxiliary antennas for transmitting information to and receiving information from the endpoint nodes via low-frequency wireless data links;
- wherein the aggregation node comprises, for the high frequency data links, one or more WiFi chipsets for producing WiFi signals, block up converters for upconverting the WiFi signals to high frequency signals of 10 and 300 Gigahertz for transmission to the endpoint nodes via the phased array antenna system and block down converters for receiving high frequency signals of 10 and 300 Gigahertz from the endpoint nodes via the phased array antennas and downconverting the high frequency signals to WiFi signals to be processed by the one or more WiFi chipsets;
- and
- wherein the aggregation node further comprises, for the low frequency data links, a WiFi chipset for producing WiFi signals for transmission via the one or more auxiliary antennas to the endpoint nodes, and processing WiFi signals received by the one or more auxiliary antennas from the endpoint nodes and the aggregation node and the endpoint nodes exchange packet data via the low-frequency wireless data links in response to determining that the high-frequency wireless data links are impaired.
A method of operation of a wireless access system, the method comprising:
- an aggregation node transmitting information to and receiving information from endpoint nodes installed at a premises via high-frequency wireless data links using a phased array antenna system of the aggregation node, wherein the aggregation node comprises, for the high frequency data links, one or more WiFi chipsets for producing WiFi signals, block up converters for upconverting the WiFi signals to high frequency signals of 10 and 300 Gigahertz for transmission to the endpoint nodes via the phased array antenna system and block down converters for receiving high frequency signals of 10 and 300 Gigahertz from the endpoint nodes via the phased array antennas and downconverting the high frequency signals to WiFi signals to be processed by the one or more WiFi chipsets;
- and
- the aggregation node transmitting information to and receiving information from the endpoint nodes via low-frequency wireless data links using one or more auxiliary antennas of the aggregation node, wherein the aggregation node further comprises, for the low frequency data links, a WiFi chipset for producing WiFi signals for transmission via the one or more auxiliary antennas to the endpoint nodes, and processing WiFi signals received by the one or more auxiliary antennas from the endpoint nodes, the aggregation node and the endpoint nodes exchanging packet data via the low-frequency wireless data links in response to determining that the high-frequency wireless data links are impaired.
The method as claimed in 9, further comprising the aggregation node and the endpoint nodes resuming exchanging the packet data via the high- frequency wireless data links in response to determining that the high-frequency wireless data links are no longer impaired.
A wireless access system, the system comprising:
