Choosing a Wireless Network Configuration

The antennas you need depend on the wireless network configuration:

∙LAN-to-LAN, Point-to-Point

This is a wireless link between two Access Points that connects two separate wired LANs. Typically, two directional antennas are used.

∙LAN-to-LAN, Point-to-Multipoint

In a point-to-multipoint network, up to seven Access Points provide wireless links to connect up to seven LANs. One Access Point is designated as the central (multipoint) Access Point. The other Access Points are called endpoints and only communicate with the Central Access Point. Typically, the Central Access Point connects to an omni-directional antenna. The endpoint Access Points connect to a directional antenna.

∙Wireless Infrastructure

This is an inside/outside wireless network where one or more Access Points are used to connect clients to a wired LAN. Typically, the Access Points use an omni-directional antenna or a sectored antenna, and the clients use a vehicle-mount antenna. An example of this type of network is a warehouse where drivers in forklifts need to access the LAN.
