Installation Guidelines
Allied Telesis recommends that you have an Allied Telesis-certified RF specialist conduct a site survey to
determine the ideal locations for all your Allied Telesis wireless network devices. To conduct a proper site
survey, you need to have proper equipment and training.
The following general practices should be followed in any installation:
• Locate access points centrally within areas requiring coverage.
• O verlap access point radio coverage areas to avoid shadow areas.
• Position the access point so that its LED s are visible. The LED s 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 Telesis representative.

degradation from microwave ovens, cordless telephones, and other access points. For more information,
