1.2 Wireless Network Topology
1.2.1 Point-to-Multipoint (PTMP)
Point-to-multipoint is a wireless network that has a central communication device such as a Base Station Unit (BSU), providing
connectivity to multiple devices such as Subscribers (SUs) or clients. Any transmission of data that originates from the BSU is
received by all SUs; whereas, the data originating from any of the SU is received only by the BSU. This allows numerous sites
in a wide area to share resources, including a single high-speed connection to the Internet.
Given below are the deployment scenarios, where Proxim's point-to-multipoint devices are recommended. The Proxim devices
used in the deployment images are commonly referred to as BSU (Base Station Unit) and SU (Subscriber Unit). The
combinations that are used for BSU and SU multipoint devices are:
