MEA Setup and Installation
Network Architecture
The basic MEA network utilizes two subnets, one for the MEA wireless elements and one for the
server elements. For seamless IAP mobility, all of the MEA wireless elements must be in the
same subnet. The subnets are connected together by the core router, and the edge router
provides Internet connectivity.
Figure 3 shows the logical network layout of a MEA network.

Unified Modes of Operation
With MEA Release 3.0, the concept of modes has been replaced by unified modes of operation
addressing scheme. The concept of unified modes of operation centers on the current state of network
communication: Associated State and Unassociated State. There are three addressing schemes that
allow the IT manager increased flexibility in deployment.
