Wireless LAN Communications with 802.11b
Overview
Dolphin 9500 Series terminals are available with an on-board 2.4 GHz 802.11b (Wireless Local Area Network) WLAN radio that
uses Direct Sequence Spread Spectrum (DSSS) technology to spread the signal continuously over a wide frequency band at a
data rate of up to 11 Mbps. In addition, the open software architecture makes the Dolphin 9500 Series a complete solution for a
variety of wireless mobile data collection applications.
The Dolphin 9500 Series is interoperable with other 802.11b Wi-Fi-compliant products including Access Points (APs), printers,
PCs (via PC card adapters) and other wireless portable terminals.
