Read range

Read range describes the maximum distance at which an RFID system can still reliably detect a tagged object. It is determined mainly by the RFID antenna and the transmit power. Frequency, the orientation of the tag and electromagnetic interference also affect how stably a signal is transmitted in real operating conditions. For this reason, the actual range often differs from values measured under ideal conditions. Unlike the read zone, read range refers primarily to distance rather than to the entire effective reading area. The correct adjustment of read range ensures that objects are captured reliably at gates, conveyor lines and workstations.
