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.
