Point-to-Point Link
With a BSU and an SU, it is easy to set up a wireless point-to-point link as depicted in the following figure.
A point-to-point link lets you set up a connection between two locations as an alternative to:
• Leased lines in building-to-building connections
• Wired Ethernet backbones between wireless access points in difficult-to-wire environments
Point-to-Multipoint Network
If you want to connect more than two buildings, you can set up a single point-to-multipoint network with a single
BSU and multiple SUs, as depicted in the following figure.
Up to 250 SUs can be connected to a BSU. If a BSU already has 250 SUs, a new SU cannot be connected to the
BSU. In the previous figure, the system is designed as follows:
• Central building B is equipped with a BSU, connected to either an omni-directional or a wide angle
antenna.
• The buildings A and C are each equipped with an SU connected to a directional antenna.
