2.6.5 Wi-Fi slot
The PCI 5 slot and the Wi-Fi slot may not be used at the same time.
The Wi-Fi (Wireless Fidelity) slot will support the ASUS Wi-Fi module
when available. Visit the ASUS website (www.asus.com) for product
updates.
The Wi-Fi slot conforms to the Institute of Electrical and Electronics
Engineers (IEEE) 802.11b standard for wireless devices operating in the
2.4 GHz frequency band.
IEEE 802.11b introduction
The IEEE 802.11b standard includes provisions for three radio
technologies: direct sequence spread spectrum, frequency hopping
spread spectrum, and infrared. Devices that comply with the 802.11b
standard operate at data rates of up to 11 Mbps for direct sequence
spread spectrum.
The IEEE 802.11b specification allocates the 2.4 GHz frequency band into
14 overlapping operating channels. Each Channel corresponds to a
different set of frequencies. If operating multiple 802.11b wireless PCI
cards in the same vicinity, the distance between the center frequencies
must be at least 25 MHz to avoid interference.
The channels available to an 802.11b wireless PCI card will vary from
country to country. In the United States, the 802.11b standard allocates 11
operating channels for direct sequence devices. Channels 1, 6, and 11 are
independent and do not overlap with each other.
