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(shuō)明書(shū)

FIGS. 10A and 10B illustrate a sixth example use case of the bridge 102, arranged in accordance with at least one implementation described herein. FIGS. 10A and 10B illustrates the bridge 102 and a LAN 1000 at a house, building, or other location 1002. The LAN 1000 may include the AP 106 and/or the first STA 108A.

The bridge 102 may improve coverage for STAs 108 such as the first STA 108A that have associated with the AP 106 in the past and move to locations with inadequate coverage from the AP 106 and with adequate coverage from the bridge 102. For example, referring to FIG. 10A, the first STA 108A may associate with the AP 106 within the house 1002 where the AP 106 has adequate coverage for a connection. As illustrated in FIG. 10B, however, if the first STA 108A moves to a location outside of the house 1002 or otherwise outside a coverage area of the AP 106 and within a coverage area of the bridge 102, the bridge 102 may extend coverage to the first STA 108A.

The bridge 102 may periodically or in response to a trigger replicate a BSS of the AP 106. If link setup occurs, e.g., if the first STA 108A sends an association request to the bridge 102, the bridge 102 may maintain the BSS and establish a link directly between the first STA 108 and the bridge 102 to send traffic to the first STA 108 while bypassing the AP 106.
