SpectraLink Voice Priority (SVP) Overview

In order to enhance voice quality over the wireless network, SpectraLink has developed a quality of service (QoS) mechanism that is implemented in the wireless telephone and access point. This mechanism, SpectraLink Wi-Fi Voice Priority, or SVP, gives a controlled preference to voice packets over data packets on the Wi-Fi network, increasing the probability that all voice packets are transmitted efficiently. SpectraLink Voice Priority is an open specification that is compliant with the IEEE 802.11b standard.

Features

Minimises latency for voice packets
- Provides priority queuing for voice packets
- Ensures predictable, timed delivery of packets
- Provides admission control to avoid over-subscription of access points
Implemented in wireless LAN access points, handsets, gateways, and SVP Server.
- 802.11b-compatible
- Software upgradeable

SVP Server Overview

The SpectraLink Wi-Fi SVP Server is the hardware component of the system that ensures excellent voice quality is maintained on a shared wireless voice and data network. The SpectraLink Wi-Fi SVP Server can support thousands of users, depending on the number of SpectraLink Wi-Fi SVP Servers and the average wireless telephone usage.

Features

Dedicated network appliance
Provides SVP encapsulation of voice packets to allow prioritization in access points
Multiple configurations available to provide cost-effective scalability
- Supports small, traditional PABX customers (<64 users) with four or fewer SpectraLink Telephony Gateways.
- Supports large, traditional PABX customers with a maximum of 40 SpectraLink Telephony Gateways (approximate 640 users) with a single SVP Server.
- Supports small IP Telephony customers with SVP 10 and 20 user configurations.
- Supports large IP Telephony customers with a maximum of 16 SVP Servers (approximate 8,000 users).
