Firmware design for a multi-protocol UHF RFID reader

The development of monostatic multi-protocol UHF RFID interrogator is presented. It utilizes highly integrated IDS-R902DRM reader IC, enabling cost-efficient solutions with minimum mechanical dimensions. This IC also includes dense reader mode function which prevents reading conflicts in a multi-reader environment. Emphasis is placed on the firmware design. Implementation of each supported RFID protocol is briefly described. Final part is devoted to the discussion of regulatory requirements in the European Union and in the USA.
