Gold wireless routers.

Figure 2-1 Point-to-Point Topology

The range and interference immunity that can be achieved with packet-

based point-to-point topology is maximized by the use of highly

directional antennas on both sides of the link.

PEER-TO-PEER TOPOLOGY

In peer-to-peer topology (unique to packet-based networks), there are

three or more nodes, any one of which can communicate directly with

any other node. Since each node has direct access to every other node,

the time delay for transferring data between nodes is the least for this

type of topology, unless WAN traffic is very high. However, this also

implies that each node must have a clear communication path to every

other node, that is, there must be clear line of sight.

An example of a three node peer-to-peer topology is shown in Figure 2-

2 on page 2-3.
