protected configuration for the Access Point to greatly reduce the possi-
bility of this occurrence.
Two or more Access Points can be configured identically, each with its
own independent antenna. In this scenario, Remotes will associate with
one of the available Access Points. In case of a failure of that AP, the
Remotes will quickly associate with another Access Point, re-estab-
lishing connectivity to the end devices. Because only one Access Point
operates at any given time, collisions between APs is not possible.

1.4.3 Collocating Multiple Radio Networks

Many networks can operate in relatively close physical proximity to one
another provided reasonable measures are taken to assure the radio
signal of one Access Point is not directed at the antenna of the second
Access Point.
The Network Name and the Association Process
The Network Name is the foundation for building individual radio net-
works. Remotes in a network with the same network name as an Access
Point (AP) unit are "associated" with that AP.
The use of a different Network Name does not guarantee an interfer-
ence-free system. It does, however, assure that only data destined for a
unique network is passed through to that network.
It may be desirable to co-locate Access Points at one location to take
advantage of an excellent location that can serve two independent net-
works. Configure each network with a unique Network Name, and
install each AP's antenna with at least 10 feet of vertical separation to
minimize RFI.
To co-locate APs, configure them with Time Division Duplex (TDD)
Sync set to

Can radio frequency interference (RFI) disrupt my wireless
network?
When multiple radio networks operate in close physical proximity to
other wireless networks, individual units may not operate reliably under
weak signal conditions and may be influenced by strong radio signals on
adjacent bands. This radio frequency interference cannot be predicted
with certainty, and can only be determined by experimentation. If you
need to co-locate two units, start by using the largest possible vertical
antenna separation between the two AP antennas on the same support

as a factory default.
