System Components
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,
