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.
Configuration Utility Options
There are two configuration utilities for the 802.11b radio: 802.11b Settings (default) and the 802.11b Wireless Security
Supplement.
802.11b Settings 802.11b Settings is the default configuration utility and should be used to configure the radio with
standard WEP (64/128 bit) and no authentication. For more details, see 802.11b Settings later in
this chapter.
If you chose to set up the radio with 802.11b Setting, remove the 802.11b Wireless Security
Supplement from the device; see Removing the 802.11b Wireless Security Supplement on
page 8-2.
802.11b Wireless Security Supplement
The 802.11b Wireless Security Supplement (also known as the AEGIS Client) is an additional
configuration utility you should use when configuring the radio using WEP (beyond the standard),
Wi-Fi Protected Access (WPA), and authentication.
For details, see 802.11b Wireless Security Supplement later in this chapter.
