The article discusses an emerging application in networking, Radio Frequency Identification (RFID), which will place significant new demands on many enterprise network infrastructures, particularly in the retailing, manufacturing, transportation and distribution industries. RFID uses electronic tags that replace printed bar codes to track the location of shipped items. Providing connectivity to a large number of RFID readers will require extending enterprise networks. Two principal alternatives for reader connectivity back to the enterprise network include wired Ethernet or wireless LANs. The other alternative, wireless LAN, has its own advantages and concerns. RFID readers typically operate at 900 MHz, so there is little chance of interference with WLANs transmitting at 2.4 GHz or 5 GHz. The big advantage of WLANs for RFID reader connectivity is their flexibility-making it easy for workers to place readers where required for coverage without having to worry about network connectivity.
