30.1 Wireless LAN
Wireless LANs have become an indispensable aspect of mobile computing. Today,
most laptops have built-in WLAN cards. The 802.11 standard for the wireless commu-
nication of WLAN cards was prepared by the IEEE organization. Originally, this stan-
dard provided for a maximum transmission rate of 2 MBit/s. Meanwhile, several sup-
plements have been added to increase the data rate. These supplements define details
such as the modulation, transmission output, and transmission rates:
