Throughout the remainder of this
section, we will assume a deployment using mesh equipment.
A typical deployment consists of a wireless service POP ???lit??? by a metro ring or some
form of backhaul connection. The POP may consist of a Carrier Ethernet??“grade networking
service either as an aggregation point or a NNI interface. The POP would
serve as a service injection point.
The roof of the POP building may be populated with one or more optical wireless
mesh devices, referred to as nodes. Some of the buildings within the specified range
that are in line-of-sight of the POP may also be populated with one or more of the nodes.
Optical wireless connections among the nodes would create a mesh network.
Each of the buildings would consist of an indoor CLE device for the distribution of
the services throughout the building, which may define the UNI interface. In the event
that only a small number of UNIs are required, the node may also provide the UNI,
obviating the need for a CLE switch.
From each building with a node, the mesh may be further extended to additional
buildings that are within range and in LOS of one of the nodes. The expansion to additional
buildings may be done on a need-to basis.
