SpectraLink 8000 Wireless Telephones
SpectraLink 8000 Wireless Telephones use voice over IP (VoIP)
technology on IEEE 802.11b-compatible wireless local area networks
(WLANs). Access points utilize radio frequencies to transmit signals
to and from the SpectraLink 8000 Wireless Telephones.

Access Point Capacity and Positioning
Each site is unique in its AP requirements. Please take the following
points into account when determining how many APs are needed and
where they should be placed in the facility.
Handset range
There must be wireless LAN coverage wherever SpectraLink 8000
Wireless Telephones will be used. The typical range for a SpectraLink
8000 Wireless Telephone is comparable to that of a laptop computer
utilizing a wireless LAN PC card. However, SpectraLink 8000
Wireless Telephones are likely to be used in areas where data devices
are not typically used, such as stairwells and outdoor areas.
SpectraLink 8000 Wireless Telephones have a Site Survey mode that
displays dBm levels to determine adequate WLAN coverage. Refer to
the Administration Guide for your SpectraLink Wireless Telephones
for details about this feature.
Number of handsets per access point
Estimate the number of SpectraLink 8000 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
SpectraLink 8000 Wireless Telephones will be operating near the
limits of the RF coverage from the AP, they will automatically drop to
1 Mb/s operation. SpectraLink 8000 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 11 Mb/s operation.
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 SpectraLink 8000 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 SpectraLink 8000 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.

Access Point Configuration
The following AP configuration steps need to be repeated for each AP
radio that you are planning to use with VoIP.
1. Connect to the AP using the Web browser interface. Consult the
access point documentation for details.
2. Go to IEEE 802.11B Radio and set the SSID (Network Name) on the AP
the same as the setting for the SpectraLink 8000 Wireless
Telephones.
3. Go to IEEE 802.11B Radio: Advanced Configuration and set Data/Voice
Settings option to Data and SpectraLink Traffic.
4. Go to IEEE 802.11B Radio: Advanced Configuration and set the Basic
Rate to 11Mb/s.
5. Go to Spanning Tree Settings: Global Flooding, set Multicast Flooding to
Universal (Inbound)
6. Save changes and reboot.
The AP is now ready for use with SpectraLink 8000 Wireless
Telephones.
