Characteristics of Wireless LANs
nAdvantages
–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...
nDisadvantages
–typically
very low bandwidth compared to wired networks
(1-10 Mbit/s)
(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
