RFID tag performance is traditionally evaluated based on read range. But another factor plays just as big of a role and is often overlooked: bandwidth. Most sellers and users of RFID tags only characterize tag performance by one factor: read range. There are situations where it makes since for read range to be a shorthand for tag performance. But response bandwidth that can have a significant effect on a tag’s performance in real world applications. Overlooking it can cost you read range and performance. RFID FREQUENCY BANDS RFID readers in North America operate in the 902-928 MHz frequency band. The readers ‘frequency hop’ within this band, changing frequencies at random. The purpose of this hopping is to avoid interference with other readers in the vicinity. Frequency bandwidth is the ability of a component to respond to signa...
