Unit 3: Radio Frequency and Light Signal Fundamentals

This technology allows data from a portable computer or a Personal Digital Assistant (PDA) Notes
to be transmitted to Wide Area Computer Networks (WAN) and Public Switched Telephone
Networks (PSTN) as well as other mobile units ie: mobile phones or portable computers. This
allows individuals total freedom to transmit data back to the office from remote locations.

Case Study Stark RFID-Enabled System Helps Brick And Ceramic
Product Manufacturers Improve Inventory Control And
Delivery Accuracy
he growing acceptance and reliability of RFID technology for supply chain
management and asset tracking is spurring software companies to develop RFID
Tsolutions that will help them penetrate new markets.

One such example is Stark RFID, based in Greenville, South Carolina, a systems integrator
and provider of turnkey RFID solutions designed to transform supply chain efficiency for
brick and refractory products manufacturers. The company’s innovative StarkFG™ RFID
application delivers an accurate, real-time asset tracking solution that greatly improves
inventory visibility, management and control.

According to Lance Burnett, the company’s co-founder and president, although this
market sector has adopted technology-based enterprise solutions for running business
processes efficiently, a large majority of companies still rely heavily on manual processes
for managing inventory and fulfilling orders.
“For these industries, the challenge of managing inventory is due in large part to the sheer
volume of manufactured products in the brickyard or warehouse, which makes manual,
line-of-sight inventory difficult, if not impossible,” says Burnett. “As we explored the
capabilities of RFID technology, we decided to be first-to-market with an inventory tracking
system that would make the job faster and easier. Now, having implemented StarkFG in
several customer sites, it is clearly proving to be a transformative RFID solution.”
Brick Industry Challenges
Brick manufacturers serve the residential and commercial construction industries, typically
selling through distribution channels to builders and contractors. In the commercial
building market especially, where on-site labor costs are high and sequential workflow is
