Wireless factory keeps on humming

HUMVEE maker AM General has adopted WhereNet’s WhereCall wireless technology at its Hummer factory in Mishawaka, Indiana.

WhereCall provides an electronic means for assembly-line operators to request bulk material replenishment, providing an alternative to paper-based Kanban parts replenishment systems or hardwired electronic call systems. When supplies on the line start to run low, a line side operator presses a button on a WhereCall pendant that sends a request specifying the type of material required and its delivery location.

AM General is also going to use the WhereNet wireless system in conjunction with the GE Fanuc CIMPLICITY Tracker application to monitor work in progress.

While standard Tracker applications receive data from bar codes or passive RFID tags, the reliability of the information is often compromised due to missed or improper scans.

To support 98% accurate data capture, the AM General Tracker application will be integrated with the WhereNet wireless system comprised of 18 antennas, more than 60 active radio frequency WhereTag transmitters and 50 WherePort devices.
