SpectraLink 8020/8030
Wireless Telephone Overview
SpectraLink 8020/8030 Wireless Telephones are mobile handsets for
workplace telephone systems. The handset operates over an
802.11a/b/g wireless Ethernet LAN providing users a wireless voice
over IP (VoIP) extension. By seamlessly integrating with the
SpectraLink 8000 Telephony Gateway and the facility’s telephone
system, handset users are provided with high-quality mobile voice
communications throughout the workplace. The handset gives users
the freedom to roam throughout the workplace while providing all
the features and functionality of a desk phone.
The handsets reside on the wireless LAN with other wireless devices
using direct-sequence spread spectrum (DSSS) radio technology. The
handset radio transmits and receives packets at up to 54Mb/s.
All Polycom products use the company’s LinkPlus integration
technology to connect with various digital switch platforms. Using
LinkPlus technology, handsets emulate digital telephone sets to
deliver advanced capabilities such as multiple line appearances and
LCD display features. See the LinkPlus Interface Guide for your PBX for
information about mapping the PBX features to the handset.
SpectraLink Voice Priority (SVP) and
Quality of Service
SVP is the SpectraLink quality of service (QoS) mechanism that is
implemented in the handset and access points (APs) to enhance voice
quality over the wireless network. SVP gives preference to voice
packets over data packets on the wireless medium, increasing the
probability that all voice packets are transmitted efficiently and with
minimum or no delay. SVP is fully compatible with the IEEE 802.11
standards.
