What spread spectrum technology can do for you

PREAD spectrum technology is increasingly being utilized by retailers to transmit information over radiowaves. It is typically used with barcoding because barcodes allow for the accurate collection of information, while spread spectrum ensures this information is communicated fast and accurately.

Kmart recently began using hand-held portable data collection devices and spread spectrum technology so associates could scan barcoded items and then access a data base in order to retrieve inventory information immediately. Based on the information retrieved, reorders can be placed on the spot. In addition, price verification, inventory counts, wireless checkout locations, and shipping and receiving functions are all applications either being performed or in the development stages for them.

A National Research Council of Canada study demonstrated that spread spectrum was able to provide data communications used in controlling an automatic guided vehicle (AGV) more reliably and at lower cost than a narrow band approach.

The costs for the use ofthe technology can vary quite a bit based on the application and volume of equipment needed. However, Kmart said their $25 million investment in this technology for neady 3,300 oftheir stores is expected to pay for itself in approximately two years. Naturally, the benefits are possible for those who invest far less than $25 million.

The trainingrequired forthe use of spreadspectrum isnot unlike that for other systems utilizing new technology. In other words, users must be involved as early in the planning stage as possible since. they know their jobs better than anyone else. As well, users must be sold on the benefits and why their company has made this investment. Finally, users must gain a complete understanding of the equipment prior to installation, so that they can help make the systems

successful.

What spread spectrum can provide is "real time" information over the airwaves in order to give businesses up-to-date information that can allow for greater productivity. For those with a vision toward the future, spread spectrum technology may well provide benefits beyond compare.
