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,
