or LANs can be converted completely to a wireless structure.
A further useful purpose for WLAN technology is to link seg-
ments of existing cable-connected networks.
Although WLAN was actually developed only for short-range
connections, by cascading WLAN base stations or implement-
ing transmission networks with high-power point-to-point ra-
dio transmission, even network segments located further
away from each other can be linked or network participants in
relatively remote locations can be economically and easily in-
tegrated into an existing network.
WLAN base stations often also serve as access points to the
Internet in private or public institutions. Many airports, hotels
and cafes, for instance, make WLAN hotspots available to
their customers, either free or subject to a charge. Ultimately
this has maneuvered WLAN into serious competition with mo-
bile UMTS technology.
The application possibilities for wireless network communi-
cation also overlap with Bluetooth technology. For mobile de-
vices with limited energy capacity Bluetooth is the more use-
ful solution, however, as Bluetooth uses considerably less
power than wireless LAN. What is more, Bluetooth technology
is more flexible and thus can offer a greater bandwidth of po-
tential applications.
