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:
ˆ Locate access points centrally within areas requiring coverage.
ˆ Overlap access point radio coverage areas to avoid coverage
holes.
ˆ Position the access point so that its LEDs are visible. The LEDs
are useful for troubleshooting.
ˆ Install wired LAN cabling within node limit and cable length
limitations.
ˆ 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.
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.
