•Monitor: Description of how to monitor the system

•Command Line Interface: Description of Command Line Interface (CLI) syntax

1.1 Wireless Network

A wireless network is a flexible data communications system that extends the capability

of the existing wired network to provide connectivity for wireless devices. Unlike the

traditional wired network which relies on physical cables and wires to transmit and

receive data, a wireless network relies on radio frequency (RF) technology to transmit

and receive data.

A Wireless Access Point (AP) is a device that connects wireless communication devices.

It is usually connected to a wired network on one end, and relays data to the wireless

network on the other end.

The advent of the wireless network opens up the possibility of what a network

infrastructure can be. Without the restriction of wires, the network can move with users

and change as fast as the organization does. Figure 1.1 illustrates a sample wireless

network.

Figure 1.1 Wireless Networks

1.2 Wireless LAN Bridge

Cedar Wireless Access Point provides the capability of being configured as a regular

Access Point, a Wireless LAN Bridge or both. A Wireless LAN Bridge wirelessly

connects two ore more Ethernet LANs together. It is a very practical, easy and in most

cases inexpensive way to connect Ethernet LANs or extend the range of existing

WLANs. As illustrated in Figure 1.2 and 1.3, the access point can operate in point-to-

point or point-to-multipoint bridge topology.

Point-to-point

Point-to-point link allows you to use two access points to bridge two Local Area

Networks from different locations. Access point A serves as a base bridge while Access

point B serves as a non-base bridge. Both access points relay data between the two

Cedar 880AG Enterprise Dual-Radio AP/Bridge

networks. This is an ideal topology for connecting main office with warehouse, or

between office buildings.

Figure 1.2 Point-to-Point Bridge

Point-to-Multipoint

Point-to-Multipoint Bridge allows you to use multiple access points to bridge Local Area

Networks from different locations. Access point A serves as a base bridge while Access

point B and C serve as non-base bridges. This is an ideal topology for central office to

collect data from remote offices.

Figure 1.3 Point-to-Multipoint Bridge Mode

1.3 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
