What are the six major technical requirements of wireless remote control?

Infrared light emitting diodes used extensively in wireless remote controllers emit infrared wavelengths of about 940 nm. They have the same shape as ordinary light emitting diodes, but different colors. Next, I would like to introduce six technical requirements for wireless remote control.

(1) modulation distortion. (after demodulation, the reduction rate of data);

(2) transmitting power. Including harmonic suppression. Spurious radiation suppression.

(3) working voltage range.

(4) transmit frequency skewness, sound frequency should be in positive and negative 150KHZ range.

(5) launching directivity

(6) data modulation rate range

(7) working current.
