                        Meru Networks WLAN Controllers with AP100, AP201, AP208 Configuration Guide  Field Verified  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 d

The mechanism uses multicast data delivery to communicate within the  wireless neighborhood. With guaranteed coverage across all access points, push-to-talk often  operates on a base rate as low as 1Mbps. Only a s

In the Meru solution, creating a VLAN entry in the controller and assigning  it to the SVP ESSID achieves this. This is an optional configuration component.    vlan  SVP_VLAN tag  1001        ip address  10.4.0.250  255.255.0.0      ip default-gateway  10.4.0.1        ip d

It is important to note that when enabling the multicast support (for the server discovery and  PTT feature) you must ensure that there is only one ESSID per VLAN otherwise multicast  traffic is not pas
