A wireless mouse is a computer input device that uses wireless communication technology to connect to a host computer, eliminating the constraints of cables through technologies such as Bluetooth, Wi-Fi, Infrared (IrDA), ZigBee (IEEE 802.15.4), and 27MHz RF. Logitech pioneered this technology in 1984, and after adopting 27MHz RF technology in 1994, it gradually evolved into 2.4GHz non-networked solutions, 5.8GHz, and Bluetooth technologies. Bluetooth 5.0 technology can extend the transmission range to 300 meters and achieve speeds of up to 2Mbps.
The technology types include 27MHz RF using the ISM band and 2.4GHz solutions with different channels. These devices require battery power and have limitations such as high power consumption, the need for pairing adapters, and higher price.
