Operational View of the MEA System
Figure 2 shows the different ways a subscriber can reach an IAP. It can connect directly, or hop
through any number or combination of WRs and SDs. Additionally, if the subscriber wishes to
execute a peer-to-peer application such as a file transfer, the subscriber can communicate
directly, or through any combination of SDs, WRs, and IAPs.
The ability to use ad hoc routing to forward traffic improves the scalability of the mobile wireless
network. In particular, the ability for the user to accomplish a peer-to-peer application without
the use of infrastructure has tremendous advantages.
A significant problem in every mobile wireless network is backhaul. The MEA architecture
provides the ability to route traffic from applications through SDs and WRs without ever reaching
an IAP or the wired network. This reduces the amount of backhaul required by enabling the
SDs to accomplish the backhaul whenever the opportunity arises. In turn, this results in lower
deployment costs, reduced backhaul, and lower operating expenditures. The service provider
can provide the same level of service with less equipment by empowering the SDs with ad hoc
networking capability.
