Radio Frequency Data Communication System
With LXE's Radio Frequency Data Communication (RFDC) data is collected in real-time by
operators using mobile data devices.
Integration is accomplished by using a qualified 2.4 GHz PCMCIA radio.
The PCMCIA radio in the DOS computer communicates with Access Points (APs). Access Points
communicate with either an LXE Telnet Manager (TM1) or the LDS Controller using an Ethernet
link.

The
wire-linked system
physically links a host computer to remote computers with wires. This link
obviously restricts the mobility of the computer operators and prevents them from moving about
freely (as in a warehouse application).
A
radio frequency data communication system
uses radios to link remote computers to a host
computer. RFDC allows RF computer operators to roam while communicating with a host
application in real-time.
