non-root bridge are deployed with wireless clients to bridge through the root bridge to the Internet cloud.
If the range is short, the bridges can support wireless clients and maintain high-bandwidth availability.

Point-to-Multipoint Bridging

In a point-to-multipoint bridge configuration, two or more non-root bridges associate to a root bridge.
Up to 17 non-root bridges can associate to a root bridge, but the non-root bridges must share the available
bandwidth.
Using point-to-multipoint connection, multiple remote sites such as buildings can be linked together into
a single logical network. In a point-to-multipoint architecture, these remote sites are linked to a single
root bridge at a centralized site, and share the available bandwidth over the wireless link. This lowers
the overall infrastructure cost per site, but might also lead to lower average throughput.
Point-to-multipoint links might require additional design efforts such as traffic and capacity planning.
The root bridge acts as the master in the network relationship between the bridges and is usually in the
logical center of the topology. In a point-to-point or point-to-multipoint network. However, if there is
more than one cell in a point to multipoint network, non-overlapping channels must be used.
