2 - Installing the Access Points

Installation Guidelines
The following general practices should be followed in any installation:
‰ Locate access points centrally within areas requiring coverage.
‰ Overlap access point radio coverage areas to avoid coverage
holes.
‰ Position the access point so that its LEDs are visible. The LEDs are
useful for troubleshooting.
‰ Install wired LAN cabling within node limit and cable length
limitations.
‰ Use an Uninterruptible Power Supply (UPS) when AC power is not
reliable.
Proper antenna placement can help improve range. For information
about antenna options, contact your local Allied Telesyn representative.
For more guidelines, see External Antenna Placement Guidelines on
page 50.
When determining ideal locations for the access points, be aware that
you may see network performance degradation from microwave ovens,
cordless telephones, and other access points. For more information, see
the next sections.
Note
Microwave ovens, cordless telephones, and other access points do
not degrade the network performance of the 802.11a radio.
Microwave
Ovens
Microwave ovens operate in the same frequency band as 802.11b radio;
therefore, if you use a microwave oven within range of your wireless
network, you may notice network performance degradation. Both your
microwave oven and your wireless network will continue to function,
but you may want to consider relocating your microwave oven out of
range of your access point.
For the 802.11b radio, the access point has a Microwave Oven
Robustness parameter that you can enable to minimize potential
interference between your microwave oven and your wireless network.
