Transmitted data are modulated using Amplitude Shift Keying (ASK) modulation. Received data are demodulated from the tag load variation signal, generated on the antenna, using Bit Phase Shift Keying (BPSK) coding of an 847kHz sub-carrier. The Transmitted ASK wave is 10% modulated. The Data transfer rate between the CRX14 and the tag is 106Kbit/s in both transmission and reception modes.
