The European Project SELECT gave the motivation to investigate the combination of UWB and RFID technologies, which are expected together to overcome many limitations of current narrowband RFID devices. Thus, this work was developed with the intent to study UWB RFID systems based on the modulation of the backscattered signal considering different related issues. In addition, when tag cost, size and power consumption become stringent requirements, (semi-) passive solutions based on the modulation of the backscatter signal represent a good choice. Among all the technologies, radio frequency identification (RFID) seems one of the most promising. ![]() ![]() In the recent years, the idea of the Internet of Things, that is a pervasive presence of electronics devices embedded in every-day objects, is facing a rapid adoption and will create a new era in the Internet scenario.
