Wireless mouse works via radio frequency signals. It requires an rf transmitter, rf receiver for its working. The rf transmitter is kept inside the mouse and the receiver will be connected to the computer peripheral.
The mouse records the movements and the buttons that are clicked and then transmits these through the rf transmitter via radio signals to the rf receiver. The information received by the mouse will be decoded and will be sent to the computer. RF receivers may be of 3 types, majority of them comes as built in device connected to the mouse input, it is also available as separate card that can be connected to the computers expansion slots and the 3rd variety is a separate unit that is connected to a cable going directly to the computer's peripheral input. Wireless mouse used in the market today comes with integrated receivers that goes directly to the computers peripheral input.
RF frequencies
The most commonly used RF frequency is 802.11b and 802.11g. These operates at 2.4GHz.This frequency is prefered as it has little or no interface in a home or work environment, can sent data at high speed (usually either 11Mbps or 56Mbps), it also has sufficient range for mouse operation (100 to 150 feet).
Bluetooth RF
Blutooth is similar to 802.11b and 802.11g and as it uses 2.4Ghz frequency. But it also uses a frequency called adaptive frequency to select a frequency having no or little interferance.
