Intel® PRO/Wireless 2011B LAN USB Device Users Guide 3
IEEE 802.11 devices use frequency modulation (FM) to transmit digital data from one device to
another. The radio signal propagates into the air as electromagnetic waves. The receiving device
demodulates the signal, which results in the original digital data. The radio devices transmit in the
2.4 to 2.5 gigahertz frequency range, a license-free range throughout most of the world. The actual
range is country-dependent.
1.7 Intel® PRO/Wireless LAN USB Software
Intel® PRO/Wireless LAN USB software consists of the Windows device drivers for the USB
Device and the Wireless LAN Configuration Utility. The configuration utility allows you to
evaluate device performance and display and modify the wireless LAN settings for the Intel®
PRO/Wireless 2011B LAN USB Device. Settings include the operating mode, the SSID,
transmission rate, and encryption keys used for wireless network communication.
For the network device to function in a wireless LAN, you must change the settings to match the
settings of other wireless devices in your network.
