The mouse is an extremely popular technology to interact with your computer. While the majority of mice are connected directly to the computers peripheral input via a cord and are powered by the computers main power, wireless mice are becoming extremely popular to give computer user's cordless accessibility to their mice and to interact with their computer. Wireless mice usually work via radio frequencies commonly referred to as RF. RF wireless mice require two components to work properly a radio transmitter and a radio receiver. The radio frequency is integrated inside the mouse and the mouse records its movements and buttons that are clicked and then sends this information via radio signals to the receiver
The radio frequency 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. RF receivers usually come in a few styles. The majority come as built in components that connect to the mouse input, others can be a separate card that is installed in one of the many expansion slots of computers and the third type of receiver is a separate unit that is then connected to a cable going directly to the computer's peripheral input. Since the technology has been mastered, most wireless mice have integrated receivers that plug into a computer's peripheral input and are very small.
Wireless mice mainly use Radio frequencies to transmit data from the mouse to the computer. The most common type of RF used is the 802.11b or the 802.11g and they operate at operate at 2.4 gigahertz and at these frequencies a mouse can transfer data at pretty quick speeds, usually either 11 Mbps or 56 Mbps. 2.4 gigahertz frequencies are very stable and usually have little or no interference in a work or home environment. They also have a decent range of about 100 to 150 feet, which is more than enough for mouse operation. However, another technology is steadily emerging and becoming widely used. This is the Bluetooth RF technology. It is used to connect to keyboards, printers, PDA's and headsets and uses a software called adaptive frequency hopping to choose frequencies that have no or little interference. Bluetooth has a decent range of about 33 feet.
RF wireless mice are a great technology because of their overall reliability and stability. Other forms of communication such as 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; wirelesses mice are powered by small, lightweight batteries that are either disposable or usually rechargeable with included recharging dock.RF wireless mice are also inexpensive. You can usually purchase a wireless mice for less than $50 and even as low as $25. RF wireless mice are lightweight, so it means you can move them comfortable and easily. It uses wireless mice optical sensor rather than the earlier track ball system- an important feature when you are not tied to your computer by a cord.
The three types of mice technologies are the; Mechanical- this uses small rubber to circulate distance and position. The Optical- they use light to calculate distance, position very reliable, and process information quickly. The Laser Mice- use laser light to precisely calculate movement and position. They are very precise, reliable and process information quickly.

This article touched the basics of the topic. I have 2 more resources related to the above. They are wireless mouse and input devices . They are worth a read.
