Backscattering Communications Using Classical Micro-Controller is a project based on the compelling idea proposed by  where a transmission can be done without using any RF chip. By modifying the internal state of GPIOs connected to an antenna, it is possible to modulate the backscattered signal of a remote reader. This technique allows to reduce the number of component of the system and decrease the power consumption.
This modulated power can be linked to the delta RCS introduced in  which allows to extract read range of the system.
