Whereas the scenarios discussed so far have involved connecting multiple WLAN clients to one AP (point-to-multipoint), outdoor wireless LAN systems are particularly advantageous for providing a link between two APs (point to point). By setting up a wireless link between two APs, a distant production building on extensive company premises can be very easily integrated into the company network, for example.
A point-to-point connection can also be used in difficult terrain (such as mountainous areas or islands) to provide Internet access in areas where cabling would be too expensive. With a direct line of sight between the two APs, distances of several kilometers can be bridged by this type of wireless link.
