Supported Frequency Sub-Bands
The RoamAbout PC Card supports a number of factory-programmed channels. The
number of available frequencies is subject to local radio regulations as defined by local
authorities.
In RoamAbout infrastructure environments, the RoamAbout PC Card automatically starts
operation at the frequency channel that is used by the RoamAbout AP. This frequency is
controlled by the LAN administrator who sets the RoamAbout AP configuration. The
frequency range for the RoamAbout 802.11b PC Card is 2400 - 2500 MHz. Table 4 shows
the factory-set default values for the 802.11b PC Card, which are printed in bold.
