WLIF™-Compliant Dolphin 7200 RF Terminal
The WLIF-compliant Dolphin 7200 RF
™
terminal incorporates a high performance
radio that uses frequency hopping spread spectrum technology compliant to the
Proxim ® WLI Forum/OpenAir™ specification. The radio operates at a data rate of
up to 1.6 megabits per second, with 15 independent channels available.
Frequency hopping technology is inherently secure in that the signal hops among a
variety of frequencies and, at any instant in time, the signal is broadcast on only one
frequency. The transmission remains on each frequency for only a short period (up to
0.4 second) before moving to the next frequency.
Dolphin 7200 RF is interoperable with all WLIF-compliant products to allow network
expansion as needed. It can be connected to other devices, such as printers and PCs
via PC-card adapters.
Configuring Your WLIF-Compliant Dolphin 7200 RF Terminal
The Dolphin 7200 RF Utilities program provides basic functions required to prepare
your terminals for use. The F1 Scan Demo, F2 Help, and F3 HHP Demo programs
on the main menu shown below function the same as they do for the 802.11b-
compliant Dolphin 7200 RF unit. For more information, refer to the section on the
main menu for the 802.11b terminal.
