Wireless (Select Models Only)
Hardware and Software Guide 13–4
There are 3 popular implementations of WLAN adapters:
■ 802.11b only
■ 802.11b/g
■ 802.11a/b/g
802.11b, the first popular WLAN standard, supports data rates of
up to 11 Mbps and operates at a frequency of 2.4 GHz. 802.11g,
which came later, also operates at 2.4 GHz but supports data rates
of up to 54 Mbps. An 802.11g WLAN device is backward
compatible with 802.11b devices, so they can operate on the same
network. 802.11a supports data rates of up to 54 Mbps but
operates at a frequency of 5 GHz. 802.11a is not compatible with
802.11b and 802.11g. For information on identifying the type of
device in your tablet PC, refer to the
“Identifying a WLAN
Device” section in this chapter.
