operate, the rest of the network can still communicate. It allows for continuous

connections and reconfiguration around broken or blocked paths.

Mesh networks are self-configuring. When the mesh nodes power up, the nodes hear each

other’s broadcast and a network is automatically forms. Mesh networks are also self-

healing. When a node breaks downs or a connections goes bad, the nodes re-discover an

alternative routing path. Network connectivity is thus preserved automatically. Figure 1.4

illustrates a Wireless Mesh Network.

Cedar 880 dual-radio design allows one radio focus on Wi-Fi access and the other radio

to perform mesh related tasks; thus significantly improves mesh network system

performance.

1.4 Access Point Deployment

The deployment of access point depends greatly on the building structure, the existing

wiring and the type of service to be deployed. For example, RF signals transmit much

easier through a wood-frame building than through a concrete one. For newly constructed

buildings where Ethernet cable CAT 5 is pre-installed, wiring is not a concern. For older

construction, where re-cabling is cost prohibitive, a solution which is less dependent on

wiring such as LAN Bridge may be more viable.

The access point coverage areas should overlap to ensure there are no gaps and roaming

clients always have a connection available. In addition, the number of active wireless

users and the type of service they are using (e.g. VoIP) are important factors to consider.
