WLAN IP Telephony Installation and Configuration
Routers are typically configured with filters to prevent multicast traffic from
flowing outside of specific domains. The wireless LAN can be placed on a
separate VLAN or subnet to reduce the effects of broadcast and multicast
traffic from devices in other network segments.
