An optical mesh network thus created would be capable of serving various kinds of
Carrier Ethernet services. Whether point-to-point E-Line services or point-to-multipoint
E-LAN services, the optical mesh network would be able to deliver such solutions
throughout the mesh network.
Deployment of Wireless Access Network
One of the most promising applications of optical wireless mesh with Carrier Ethernet
services is as a backhaul to interconnect RF wireless access points such as WiFi access
points.
A wireless access network may consist of several access points distributed throughout
a region, as illustrated in Figure 9.6. Such access points may be installed on small
buildings, cell towers, traffic light posts, or lampposts. Depending on the density of the
service provided, they may be spaced at 50 m to a few hundred meters.
Located with each access point is an optical wireless mesh node, enabling each access
point to be interconnected with one or more access points in its line-of-sight. The
transport technology provided to each of the access points can be provided by one or
more of the Ethernet services as defined by MEF. For example, all the access points
may be served by a single E-LAN service.
