as stairwells and outdoor areas. NetLink Wireless Telephones have a Site Survey mode
that displays dBm levels to determine adequate WLAN coverage. Refer to the NetLink
Wireless Telephone Configuration and Administration document for details about this
feature.

Number of handsets per access point

Estimate the number of NetLink Wireless Telephones and their anticipated call volume
per AP area to ensure that the maximum number of calls per AP will not be exceeded. In
this estimate, consider the data rates at which the handsets will operate. Higher data rates
can only be sustained while well within the range of the AP. If the NetLink Wireless
Telephones will be operating near the limits of the RF coverage from the AP, they will
automatically drop to 1 Mb/s operation. NetLink Wireless Telephones require
approximately 15% of the available bandwidth per call for 1 Mb/s operation,
approximately 10% of the available bandwidth per call for 2 Mb/s operation,
approximately 7% of the available bandwidth per call for 5.5 Mb/s operation, and
approximately 5% of the available bandwidth per call for 11Mb/s operation.
Note: the maximum number of telephone calls per AP quoted in the summary table
above is based on 11 Mb/s operation, and will be reduced if some or all NetLink
Wireless Telephones are operating at 1, 2, or 5.5 Mb/s.

LAN bandwidth

Estimate anticipated peak call volume to ensure that the LAN has enough bandwidth
available to handle the network traffic generated by all of the wireless devices. Network
traffic can be monitored/analyzed using a network sniffer or a simple network
management protocol (SNMP) workstation.

Number of other wireless devices per AP

The NetLink Wireless Telephones share bandwidth with other wireless devices. To
ensure adequate RF bandwidth availability, consider the number of wireless data devices
in use per AP.

Notes on Configuration

The AP must support SpectraLink Voice Priority (SVP). Contact your AP
vendor if you need to upgrade the AP software.
If you encounter difficulties or have questions regarding the configuration process,
please contact the Customer Support Hotline at (800) 775-5330. The hotline is open
Monday through Friday, 6 a.m. to 6 p.m. Mountain time.
