Wireless LAN Communications with 802.11b
Overview
Dolphin 7900 terminals are available with an on-board 2.4 GHz 802.11b WLAN (Wireless Local Area Network) 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 7900 a complete solution for a variety of
wireless mobile data collection applications.
The Dolphin 7900 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.
