摘要

Methods and systems describe herein relate to a reconfigurable multi-radio bridge that may connect a local area network (LAN) with an access point (AP) or other WAP to the backhaul and may dynamically change and/or select transmission methods. An example implementation of a reconfigurable multi-radio bridge performs a method including discovering a topology of a network that includes one or more wireless stations (STAs), evaluating a metric for each of at least two routes discovered in the topology, receiving a packet that identifies a first STA of the one or more STAs as an intended destination of the packet, selecting a route of the at least two routes over which to send the packet based on the metric, and sending the packet from a reconfigurable multi-radio bridge over the selected route toward the first STA.

說明書

Each of the TX/RX channels may be arranged to communicate at any suitable desired frequency and/or frequency band, but in at least one implementation is arranged to communicate using centimeter (cm) wave, millimeter (mm) wave, or microwave frequency wireless signals. For example, each of the TX/RX channels of the bridge 102 may operate in a cm wave band such as the 2.4 gigahertz (GHz) band, the 5 GHz band, or the 6 GHz band; a microwave frequency band such as the 28 GHz band; or a mm wave band such as the 60 GHz band. In an implementation, at least one of the TX/RX channels of the first reconfigurable radio 102A may communicate in the 6 GHz band, the 28 GHz band, or the 60 GHz band with the base station 104 over the backhaul link 112. In an implementation, at least one of the TX/RX channels of the second reconfigurable radio 102B may communicate in the 2.4 GHz band or the 5 GHz band with the AP 106 over a link 114, with the STA 108 over a link 116, and/or with the bridge 110 over a link 118. Alternatively or additionally, at least one of the TX/RX channels of the second reconfigurable radio 102B may communicate in the 6 GHz band, the 28 GHz band, or the 60 GHz band with the bridge 110 over the link 118. Each TX/RX channel of the bridge 102 may operate in accordance with a corresponding standard, e.g., any of the IEEE 802.11 standards or other standards.

The bridge 110 may be configured in the same or similar manner as the bridge 102. The bridge 110 may connect to the core network via the link 118, the bridge 102, the backhaul link 112, and the base station 104.
