Deployment Guidelines

Virtual Cell

Meru Virtual Cell technology allows for zero-handoff as the wireless IP telephones roam

through the wireless environment. This dramatically improves the quality and consistency of

client roam times. The bi-directional quality of service (QoS) provides a near toll-quality call

experience regardless of the handsets’ security context.

The Virtual Cell configuration does not provide a good configuration setting for dense wireless

IP telephone deployment. This is because both Meru Networks and the wireless IP telephone

system provide their own QoS schemes and are not centrally managed. For wireless IP

telephones, the tolerance for packet retries is very low. Wireless handsets operate on a very

tight delivery schedule and will often channel-scan elsewhere if those delivery expectations are

not met.

To maintain the benefits of Virtual Cell just mentioned and to maximize calls, we recommend

using Virtual Cell zones. A Virtual Cell zone is a zone area on a single channel containing one

or more access points. The diagrams below provide further illustration of Virtual Cell zones.

Depending on how many calls you expect to utilize per zone, the deployment may consist of

one Virtual Cell zone (one channel deployment) or multiple virtual zones (multiple non-

interfering channels 1,6,11) with each channel being a zone having one or more Virtual Cell

access points.

Avaya recommends that no more than eight concurrent calls should exist in a zone, and that

the Avaya Voice Priority Processor should be set to eight calls per access point
