Point-to-multipoint is the most popular approach for wireless communications that have a large number of nodes, end destinations or end users. Point to

and point-to-multipoint links are very popular in the wireless industry and when paired with other high-capacity wireless links or technologies such as

simulation. Often the point to multipoint links are installed to reduce the cost of infrastructure and increase the number of CPE's and connectivity.

The base station may have a single omnidirectional antenna or multiple sector antennas, the latter of which allowing greater range and capacity.

Point-to-multipoint systems can be implemented in licensed, semi-licensed or unlicensed frequency bands depending on the specific application.
