Network equipment vendors and industry watchers are sounding the alarm that RFID threatens to overwhelm enterprise networks with operational demands.
Addressing the issue are big-name companies such as Cisco and start-ups such as Reva Systems, which later this summer plans to unveil a network appliance designed to provision large-scale RFID networks and integrate them with back-end management and security resources and enterprise applications.
The problem is not the volume of traffic that RFID networks create. Rather, it is the sheer number of tags and tag readers that are anticipated. The current RFID approach can't scale to handle those numbers.
"Without an architecture for RFID, large-scale deployments are not possible," says David Passmore, research director for Burton Group. "At the reader level, in dense deployments you have to worry about RF interference, channel assignments and all that RF stuff. Most people don't have the tools and training to do that on their own."
Cisco's biggest enterprise customers are emphatic about their infrastructure requirements for RFID, says Mohsen Moazami, vice president of Cisco's Internet Business Solutions Group.
"They all say, 'If I'm going to install 10,000 RFID readers on my network, you have to ensure they are good citizens on the network,'" he says.
RFID pilots typically involve some tens of readers, installed in a few sites, scanning tags on a limited number of items. The readers radiate a signal, usually in the 900-MHz band, which activates a tag, causing it to reflect some of that received energy back, along with the unique ID number embedded in the tag's tiny processor. That number is passed back to a local server, running RFID middleware and applications to aggregate and manage the data.
Nearly all of these deployments use proprietary protocols between the tags and the readers, and the readers and the server-based software. Equipment supporting EPCglobal's Generation 2 air interface protocol, and the IETF's proposed Simple Lightweight RFID Reader Protocol, is just now being certified.
