Characteristics of Wireless LANs
n Advantages
very flexible within the reception area
Ad-hoc networks without previous planning possible
(almost) no wiring difficulties (e.g. historic buildings, firewalls)
more robust against disasters like, e.g., earthquakes, fire - or users
pulling a plug...
n Disadvantages
typically very low bandwidth compared to wired networks
(1-10 Mbit/s)
many proprietary solutions, especially for higher bit-rates,
standards take their time (e.g. IEEE 802.11)
products have to follow many national restrictions if working
wireless, it takes a vary long time to establish global solutions like,
e.g., IMT-2000
