Dolphin 7400/7450 RF Mobile Computer

The Dolphin 7400 and 7450 RF terminals integrate the basic functionality of the Batch terminal with a radio frequency interface that allows the terminal to communicate with a host computer via WLAN.

Dolphin 7400/7450 terminals have one Type II PCMCIA card slot to allow for an interface with either the Cisco 2.4 GHz 802.11b DSSS WLAN radio. The Cisco radio uses direct sequence spread spectrum (DSSS) technology, which spreads its signal continuously over a wide frequency band, and provides an Ethernet-like data rate of up to 11 megabits per second.

The security of wireless networks is greatly enhanced with the use of LEAP (Dynamic WEP), an industry-leading, centralized security solution developed by Cisco. LEAP combines several innovations including dynamic, per user, per-session WEP and integrated network logon to promote secure hassle-free enterprise deployment.

The radio may also provide up to 128-bit Wired Equivalent Privacy (WEP) encryption. WEP is used to encrypt and decrypt data signals transmitted between WLAN devices. The optional WEP security mechanism is available with 128-bit or 40-bit encryption.

Dolphin 7400/7450 RF is interoperable with other 802.11b WiFi-compliant products such as printers and PCs via PC-card adapters.

Refer to Chapters 1 and 2 in this manual for more on basic operation of the Dolphin terminal.
