Is Wi-Fi Always Necessary for RFID?

Published: April 4, 2009

Do all RFID-based systems require that users have a Wi-Fi connection, in order to work properly?


No. Many RFID interrogators include either an ethernet port or Wi-Fi, enabling them to be connected to a company’s network so that data can be passed to back-end systems. Wi-Fi can reduce the cost of cabling in a warehouse, but for many applications, companies connect their readers to the Internet using a standard CAT-5 Internet cable.
