The tag 10 stores the building 3D map URL.

The wireless communication module uses an on-off keying (OOK) modulation scheme to control the transmission speed, and includes an OOK transmission unit and a reception unit.

The transmitter of the OOK RF transmits a carrier wave when the input signal is 1, and transmits the carrier wave when the input signal is 0, and the receiver performs an inverse process thereof. The transmitter adjusts the clock according to the transmission rate to vary the transmission speed of the data, and restores the clock and data from the reception signal in the CDR (Clock Data Recovery) circuit of the receiver.

In one embodiment, the CDR circuit may be implemented by configuring a feedback circuit comprising a phase detector (PD), a low-pass filter (LPF), and a voltage controlled oscillator (VCO)

Further, in the transmitter, the data transmission speed can be adjusted by adjusting a clock input to the OOK transmission unit to a desired phase using a PLL (Phase Locked Loop).
