12CHAPTER 1: OVERVIEW OF DIGITAL WIRELESS NETWORKING

Multiple-AP Full This network topology will be used in most enterprise environments: multiple APs Coverage Network wired to an existing LAN to provide complete wireless network coverage. In this

scenario, as shown in the following figure, wireless clients can roam seamlessly between different coverage areas and remain connected to the network.

AirConnect Access

The AirConnect access point (AP) provides either a wireless peer-to-peer network

Point

coverage area, or a bridge between Ethernet-wired LANs and AirConnect wireless

 

networks. Essentially replacing the cabling of wired networks, the AP delivers

 

transparent connectivity between wireless clients, or between Ethernet networks

 

and wireless clients.

 

The AP provides an 11 Mbps data transfer rate, monitoring Ethernet traffic and

 

forwarding appropriate Ethernet messages to wireless clients over the network.

 

It also monitors wireless client radio traffic and forwards wireless client packets

 

to the Ethernet LAN.

 

The AP uses high data rate, direct sequence spread spectrum technology to

 

communicate with mobile and stationary units at distances of up to 300 feet,

 

providing high-capacity networking capability and the flexibility of mobility to

 

end users.
