LAN-to-LAN Configuration
Typically, the Access Points are configured with outdoor antennas. If you use an outdoor
antenna, you should have a professional antenna installation company perform the
installation. Contact your Cabletron sales representative or visit the RoamAbout web site
for more information about the outdoor antenna kits.
A Central Access Point uses an omni-directional antenna so that it can communicate with
multiple Access Points in different directions. The Endpoint Access Points usually use a
directional antenna pointed at the Central Access Point. The directional antenna allows you
to increase the distance between Access Points. There must be a clear line sight between
antennas to avoid a reduction in the signal level.
Point-to-Point
Figure 1-2 shows two Access Points, configured as LAN-to-LAN Endpoint Bridge mode,
in different buildings using an outdoor antenna to connect the LANs in those buildings. As
shown in the figure, both Access Points use a directional antenna. You can also configure
the Access Points to connect two LANs in the same building.
