Wireless LAN (WLAN) Communications with 802.11b

Overview

Dolphin 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 terminal a complete solution for a variety of wireless mobile data collection applications.

Dolphin terminals are interoperable with other 802.11b Wi-Fi-compliant products including Access Points (APs), printers, PCs via PC card adapters and other wireless portable terminals.

Enabling the 802.11b Radio Driver

When the Dolphin terminal initializes, the radio driver for 802.11b is installed. The terminal defaults to the 802.11b radio during initialization unless a GSM radio is installed, in which case, the terminal defaults to the GSM radio. The 802.11b radio must be enabled before you can configure the radio on a network. Verify the radio’s status before configuring.

Note: Radios are enabled manually in the Radio Manager; tap Start > Settings > Connections tab > Radio Manager.
