1.8.3 IEEE 802.11b/g

The 8330/8370 mobile computer can easily connect to legacy networks through access
points (APs). Roaming among different networks is possible.
IEEE 802.11b/g is an industrial standard for Wireless Local Area Networking (WLAN),
which enables wireless communications over a long distance. The speed of connection
between two wireless devices will vary with range and signal quality. To maintain a
reliable connection, the data rate of the 802.11b/g system will automatically fallback as
range increases or signal quality decreases.
