For example,
for delivery of carrier-grade Ethernet services, bases stations and subscriber stations
capable of meeting the demanding needs of carrier-grade Ethernet services would typically
be deployed. On the contrary, for the delivery of broadband Internet access with
SLA comparable to DSL, much simpler base stations and subscriber stations with limited
QoS capabilities may be deployed.
The number of subscribers served by each base station also varies based on the
Service-Level Agreement profiles of the services being offered. It also depends on
the traffic pattern of each subscriber and the oversubscription model that may be
used. For example, a service provider may feel comfortable oversubscribing a network
by five times while delivering 10 Mbps carrier-grade Ethernet to 35 customers
in each sector. However, another service provider with full-featured QoS capability
may be willing to serve 100 customers per sector, oversubscribing by a factor of 14.
Therefore, the actual deployment scenario, though may have the same topological
look as what is described here, would vary significantly from application
to application.
