Outdoor Point-to-Multipoint Systems
The relatively high power output in the United States lends itself to the use of these
networks in outdoor point-to-multipoint networks (Fig. 13.7c).
A classic multipoint transmission is a broadcast TV station. An omnidirec-
tional antenna at the transmitting tower links to directional antennas at the home.
Likewise, a central access point for a WLAN would connect to an omnidirectional
antenna and each remote workstation would use an outdoor directional antenna to
access the server.
