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.
