WLAN Layout Considerations, Quality of Service, and
Security
Careful planning of the Wireless Local Area Network (WLAN) layout,
attention to Quality of Service (QoS), and proper security provisions are
necessary to ensure good voice quality. For detailed guidance, see the Best
Polycom strongly recommends that you make use of a provisioning server as well
as a time server.
A provisioning server facilitates central management of software upgrades,
language support, configuration management, and diagnostic logging. The
SpectraLink 8400 Series Handsets support using TFTP, FTP, HTTP or HTTPS
servers for provisioning.
Access to a time server enables display of the current date and time on the
handset's display and verification of the time components in the handset’s
certificates.
