Using Multiple Wireless Infrastructure Networks; Using An Outdoor Antenna - Cabletron Systems RoamAbout Access Point Manual

Using Multiple Wireless Infrastructure Networks

Instead of creating multiple cells in a single infrastructure network, you can have separate
infrastructure networks. The advantages include:
•
Preventing too many users from roaming to a particular coverage area by configuring
some users to use one network, and other users to a different network. This is a form
of load balancing.
•
Creating a secure network for security-sensitive users and a general, less secure
network for other users. For example, on a college campus you can create a wireless
network that uses encryption for use by the faculty, and a wireless network that does
not use encryption for use by students.
The coverage areas of Access Points in different networks can overlap without interference
as long as they use different channels. If possible, have the Access Points use different
channels that are at least five channels apart.

Using an Outdoor Antenna

You can extend the coverage area of a wireless infrastructure network by connecting an
outdoor omni-directional (7 dBi) antenna to the Access Point.
Typically, you only use the omni-directional antenna in an indoor/outdoor environment,
such as in and around a warehouse. Also, the clients should be configured with the
RoamAbout Vehicle-Mount antennas. Refer to the RoamAbout Outdoor Antenna Site
Preparation and Installation Guide for the procedures to install a RoamAbout outdoor
antenna.
