Generally, in Campus / LAN architecture, IP domains are not used
because:
There is no IP bandwidth restriction; so, it is not necessary to limit
the number of communications between 2 locations
G711 algorithm is used to code the Voice over IP flows
Roaming
Refers to the ability to be reached (i.e.: making and receiving calls) in
a different Site or Network.
Inside a site or a network, roaming provides a wireless device the
capability to associate to an AP after a power-on or a reset of this
device.
Handover
Refers to the ability to move from one AP coverage area to another
AP without service disruption or loss in connectivity.
VLANs
These can be used to segment the IP network logically (e.g. voice
and data segmentation)
Generally, one VLAN ID is associated to one IP subnet.
It is recommended to create:
One voice VLAN for IP Phones, WLAN phone sets, IP Media Gateways
One data VLAN for WLAN laptops and desktops
One VLAN for signaling between WLAN switches (used when
tunneling is necessary between WLAN switches and a routing
function is required)
As in a traditional data infrastructure, all WLAN switches and Access
Points can be managed in several IP subnets
Note: For a large quantity of WLAN phone sets Alcatel-Lucent
recommends segmentation into several Voice VLANs
