In peer-to-peer topology, since all nodes need to talk to each other, the
range depends on the type of antennas used and the local terrain. Longer
ranges can be achieved by using directional antennas with power
splitters to connect to all sites.

In a Star topology, there is one AirPro Gold at a central location
designated as a Base Station or Star Base, and several remotes
designated as Remote Stations or Star Remotes. The Star Base acts as a
switching device. The Star Remotes communicate with each other
through the Star Base.
An AirPro Gold wireless network with Star topology can connect up to
255 wireless nodes. The MAC protocol used combines random and
polling MAC protocols, with positive Data Link acknowledgment that
improves the reliability of frame delivery.
Figure 2-3 on page 2-4 shows AirPro Gold wireless router nodes in a
star topology.
