Data Communications
Radio frequency
transmission has been with us since Guglielmo Marconi first
demonstrated wireless communications a century ago. Within 30 to
40 years of Marconi’s discovery, radios had become a fixture in
nearly every U.S. household. However, it has been only within
the last half-dozen years that wireless data transmission has
come into its own in a business environment.
RFDC first appeared in
warehouses and distribution centers as an enabling technology
for automatic identification and data capture (AIDC)
implementations, where hardwiring was unfeasible and/or
real-time updating of the host database was critical. Early
applications typically ran on PCs or controllers, scattered
throughout a facility, which were interfaced to what was
essentially a batch-oriented host. Those early systems were
costly, quirky, and limited in transaction processing. However,
they often made automated data capture a reality in environments
where hard-wired systems were impossible. Further, RFDC offered
certain advantages over hard-wired AIDC systems — interactivity
and real-time updates of inventory, shipments, or manufacturing
applications — that companies could turn to their own
competitive advantage.
Technology improvements
kept pace with RFDC’s steady growth, so that present-day RFDC-based
systems provide powerful, sophisticated, and reliable wireless
solutions for a wide variety of both local-area and wide-area
networked applications.
Five frequently cited
benefits to using Radio Frequency Data Communication are
increased database accuracy at all times, reduced paperwork,
real-time operations, higher productivity, and shorter order
response times. |
