1. Wireless 2.4g remote control: Wireless 2.4g remote control is gradually becoming popular in TV remote control. This remote control signal transmission method successfully solves the disadvantages of infrared remote control, and can remotely control the TV at all angles in the house. Including the current mainstream wireless mouse, wireless keyboard, wireless gamepad, etc. are all using this remote control type.

2. Bluetooth remote control: Bluetooth remote control is transmitted through Bluetooth to achieve a completely independent signal transmission channel, thereby avoiding interference between wireless signals of different devices. And because the Bluetooth signal transmission encryption is very good, we don't have to worry about the transmitted signal being acquired by others. As a supplement to 2.4GHz technology, Bluetooth remote control is also a development trend.

3. Infrared remote control: Infrared controls electrical equipment through non-visible light such as infrared. By turning infrared rays into digital signals that can be recognized by electrical equipment, the remote controller can remotely control electrical equipment at a long distance. However, due to the limitation of infrared itself, the infrared remote controller cannot pass through obstacles for remote control or remotely control the equipment at a large angle.
