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.

A WIRELESS MOUSE WITHOUT POWER SUPPLY
The invention discloses a wireless mouse without power supply and its preparation method. There is a signal output terminal of a circuit board which is connected to a mouse circuit of a computer. Receiving and transmitting a signal from a card is done by the powerless IC card. receiving and transmitting induction coils and paralleled capacitors are present in the circuit and it can be on a contactless and powerless IC. the keys of the mouse are coupled in series to the connecting circuit of the contactless and powerless IC chip. The eceiving and transmitting induction coils also perform the task of recieving and transmitting the signals. The coding and decoding circuit encodes and decodes the signals. The advantage of the mouse is that operation signal of the mouse can be transmitted wirelessly and also the power is not needed. simple structure, light weight and convenience are the other features.
Ultra-Low-Power 27-MHz Wireless Mouse
Reference Design
The Texas Instruments (TI) MSP430 is a family of microcontrollers typically used in
many high-performance low-power human interface device (HID) applications, such as
a wireless mouse or keyboard. Here, a wireless mouse reference design is described. It uses a MSP430 microcontroller by the Texas instruments, ADNS-3040
optical mouse sensor and a TRF7950 27-MHz transmitter module.. Also available with trhis is the hardware schematics and the hardware schematics.

Wireless Mouse
Synopsis :
The mouse is an extremely popular technology to interact with our computer. While the majority of mice are connected directly to the computers peripheral input via a cord, wireless mice give computer users cordless accessibility.
A mouse with no cord that transmits infrared or radio signals (RF) to a base station receiver. The infrared type requires line of sight to the receiver, whereas the RF variety uses radio waves that transmit in a wider pattern.
RF wireless mice require two components to work properly a radio transmitter and a radio receiver.A radio frequency (RF) transmitter is usually integrated inside the mouse. The mouse records its movements and buttons that are clicked and then sends this information via radio signals to the receiver.The radio frequency (RF) receiver usually connects to the computer's peripheral mouse input. It receives these RF signals, decodes them and then sends these signals directly to the computer as normal. Most wireless mice have integrated receivers which are very small in size.
The most common type of RF used is the 802.11b or 802.11g. These frequencies operate at 2.4 gigahertz which are very stable and usually have little or no interference in a work or home environment and at these frequencies a mouse can transfer data at pretty quick speeds, usually either 11 Mbps or 56 Mbps. Another technology that is emerging and now beginning to be used in large numbers for wireless mice is Bluetooth RF technology. Bluetooth is similar to 802.11b and 802.11g in that it uses 2.4 gigahertz frequencies, however, it also uses software called adaptive frequency hopping to choose frequencies that have no or little interference.
RF wireless mice are a great technology because of their overall reliability and stability. Infrared technology need to be in "line of sight" in order to work properly which makes using them with a mouse impractical. RF transmitter housed in the mouse requires low power. RF wireless mice are also inexpensive. Wireless mice use optical sensor technology rather than the earlier track-ball system for better accuracy.
Today, there are three different mice technologies- mechanical, optical and laser. Mechanical mice use a small rubber ball to calculate distance and position. Optical mice use optical light to calculate distance and position. A new technology that is out is Laser Mice. Instead of optical light, they use laser light to precisely calculate movement and position.
The process of pairing is required to operate receiver and transmitter on the same frequency. Security is an important issue when we are sending information over the air.

a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons.The mouse is an extremely popular technology to interact with your computer. The Apple Wireless Mouse is a one button mouse built for Macintosh computers. It was released in September 2003, although it is not widely recognized that it was Apple's primary wireless mouse until 2005.
