Installation Guidelines
Allied Telesyn recommends that you have an Allied Telesyn-certified RF
specialist conduct a site survey to determine the ideal locations for all your
Allied Telesyn wireless network devices. To conduct a proper site survey,
you need to have special equipment and training.
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 60.
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 802.11g and
802.11b radios; 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.
Cordless
Telephones
If you have an 802.11g or 802.11b radio in your access point, the radio
may experience interference from some cordless telephones. For optimal
performance, consider operating cordless telephones out of range of your
access points.
