A new study carried out by research company IDC on behalf of Cisco suggests that companies embarking on radio tagging projects need to bolster their networks. Radio tagging is a cheap and effective way of collecting data on goods in transit, whether they are luxury cars being transported by a freight company or groceries being snapped off the shelves by shoppers. However, IDC says RFID tag proliferation could lead to the potential for a major overload of data on the average corporate network. In its report - The Impact of RFID on the Network, the research firm says the deluge of information may lead to problems in processing and interpreting the RFID data coming in and even compromise the network’s ability to handle other critical tasks. According to IDC, the huge number of RFID tags, combined with the amount of data generated each time a tag is read and the frequency at which tags are read, could lead to a considerable stream of extra data that the network must accommodate. In addition, IDC says the introduction of RFID-based systems increases the need for network resiliency in order to deliver online information whenever it is requested by a tag. Storage also needs to be flexible and scalable, while device management could also prove an additional headache for network managers.
