SpectraLink 8002 Wireless Telephone 
The SpectraLink 8002 Wireless Telephone is a lightweight, durable 
handset specifically designed for mobile workplace use within a 
facility using SIP and an 802.11 wireless LAN.  The handsets are to be 
used on-premises; they are not cellular or satellite phones. 
SpectraLink 8002 Wireless Telephones use direct-sequence spread 
spectrum radio technology (DSSS) to transmit audio packets over 
wireless LAN APs that support WMM. 
Access points 
Supplied by third-party vendors, APs provide the connection 
between the wired Ethernet LAN and the wireless (802.11) LAN. 
Access points must be positioned in all areas where handsets will be 
used. The number and placement of APs will affect the coverage area 
and capacity of the wireless system.  
Access points must support WMM, WMM must be enabled and 
admission control must be disabled. 
Ethernet switch 
Interconnects multiple network devices, including the proxy server(s), 
wired IP phones and the APs. Ethernet switches provide the highest 
performance networks, which can handle combined voice and data 
traffic, and are required when using the SpectraLink 8002 Wireless 
Telephones. 
Although a single Ethernet switch network is recommended, the 
handsets can operate in larger, more complex networks, including 
networks with multiple Ethernet switches, routers, VLANs and/or 
multiple subnets. However, in such networks, it is possible that voice 
quality may suffer. Any network that consists of more than a single 
Ethernet switch should be thoroughly tested to ensure any quality 
issues are detected.  
Note that the SpectraLink 8002 Wireless Telephones cannot “roam” 
from one subnet to another. If routers and multiple subnets are in use,
