Wireless LAN
The terms “WIFI” or “wireless LAN” refer to the technology and products
needed to integrate computers, PDAs, smartphones, multimedia servers or games
consoles into a local area network WITHOUT CABLES. Often it is not possible to
install network cables in buildings, e.g. rented flats (see system example I).
WIFI is the solution to this problem: computers and WIFI compatible devices can
be arranged throughout b
uildings fully flexibly. The devices are even
connected to each other, with network printers, memory devices and the internet
through walls. When using notebooks or PDA, freedom is unlimited and there
are no longer any cables to limit mobility (see system example II).
Internet in the whole house:
Online shopping
Online banking
Media datenbank
Networks based on IEEE802.11n
are necessary for the transfer of
large volumes of data, e.g. for
video transfers or backups.
Speed of WIFI networks:
All WIFI technology is based on the IEEE 802.11 standard.
There are currently 3 subordinated standards which defined the basic
speeds for this 2.4 GHz radio technology.
