Speedway Reader ：To increase RF and Power Efficiency
With over 20 years of experience in the RFID IoT industry, I've worked across nearly every stage of the RFID product chain: Chips, Antennas, Bonding, Lamination, Readers, and System Integration. As a seasoned player in both technology and marketing, I'll try to share some best practices and practical tips about RFID to you.
Low Duty Cycle (LDC) and Single Target Inventory with Suppression (S1 Refresh) are exclusive features of all Impinj Speedway readers including the Speedway Revolution reader and Speedway xPortal gateway.
LDC enables the reader to go into a low power and low transmit mode when tags are not visible in the antenna field of view. The reader then “pings” for tags at a set interval dramatically reducing power consumption and unnecessary transmissions. When its “ping” sees a tag in the field, the reader will automatically exit LDC and begin reading tags.
Using S1 Refresh instructs the reader to continually refresh the Impinj Monza chip’s S1 flag preventing the Monza chip from being re-read while illuminated by the antenna. The reader will automatically come out of LDC mode only when new tags are in the field or when Impinj Monza chips are not able to hear the S1 refresh select command from the reader. This feature is only supported when using tags with Impinj Monza chips inside.
