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.
