Lighting apparatus

A lighting apparatus, comprising:

• a light source comprising multiple types of LED modules;
• a power module for converting an AC power to a DC power;
• a controller for generating multiple driving currents supplied to the LED modules;
• a data input module coupled to the controller, wherein the data input module receives input data to be transmitted;
• a serial-to-parallel converter module configured to convert the input data into multiple parallel data streams;
• an orthogonal frequency division multiplexing (OFDM) modulation module configured to modulate the parallel data streams onto multiple orthogonal subcarriers, wherein each subcarrier is associated with a specific frequency and carries a portion of the parallel data streams;
• a radio frequency (RF) upconversion module configured to upconvert the multiple data streams to multiple desired transmission frequencies;
• and
• an antenna module comprising multiple antennas configured to transmit RF signals corresponding to the multiple data streams.
