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

Virtual AP Zone with 1 to many APs CAC at 8 calls per zone
