Choosing Antennas for Wireless Network Configurations

Choosing Antennas for Wireless Network Configurations

The type and number of antennas that you need depend on the configuration of your wireless network. Table 1‐1 lists the general type of antenna to use for various wireless network configurations.

Table 1-1 Antennas for Wireless Network Configurations

Wireless Network

Description

Antenna Type

Configuration

 

 

 

 

 

LAN-to-LAN Point-to-Point

This is a wireless link between

Directional antennas, typically two.

(RBT-4102 only)

two APs that connects two

 

 

separate wired LANs.

 

LAN-to-LAN Point-to-Multipoint

In a point-to-multipoint network,

(RBT-4102 only)

up to nine APs provide wireless

 

links to connect up to nine LANs.

 

One AP is designated as the

 

central (multipoint) AP. The other

 

APs are called endpoints and only

 

communicate with the Central AP.

Omni-Directional antenna - to which the Central AP connects.

Directional antennas - to which the Endpoint APs connect.

Wireless Infrastructure

This is an inside/outside wireless

 

network where one or more APs

 

are used to connect clients to a

 

wired LAN.

An Omni-Directional or a sectored antenna.
