How does the wireless mouse

Today, wireless mouse are widely demanded and popular gadget which can be used as a computer, and a laptop.

However, some people do not understand how it works - because wireless mouse does not require any wires.

Jobs wireless mouse

Most wireless mice reacted withcomputer using radio frequency communications, which are required to establish such components as the receiver and transmitter. With built-in mouse transmitter transmits electromagnetic signals that tell about pressing the button and move the mouse. The receiver is connected to the computer, the mouse receives the signals and transmits them to the operating system driver wireless mouse.

The receiver can be either built-in or a separate device that can be connected to a computer in the form of a special card inserted into the expansion slot.

The same principle is used by many actionselectronic devices - cell phones, wireless networks, the garage doors, remote controls and so on. However, unlike infrared communication on which these devices work, RF communication does not require a finding of mouse and accessible to the receiver distance from each other. Gadget transmitter signal passes easily through obstacles in the form of a computer monitor or a countertop.

Synchronizing a wireless mouse

As with most modern computermice, cordless models are used in the work is not a ball, and an optical system, which significantly improves the accuracy of the gadget. In addition, the optical system allows the user to use a wireless mouse on almost all surfaces, it is important for devices that are not connected with a computer cable at least for a while.

Another advantage of RF communication - the lowest energy consumption of radio transmitters and receivers, which also weigh little, inexpensive and can be powered by batteries.

Wireless Mouse Synchronization is required forinteraction of its transmitter to the receiver, who should work on the same channel that represents a set of identification code and frequency. Due to the synchronization prevents the occurrence of interference provoked by other wireless devices and external sources.
Each manufacturer equips its wirelessMouse - some models (more expensive in the overall ranking) are sold in sync, and some need to synchronize automatically by pressing certain buttons on the device. Transmitted by the mouse data protection to the receiver, perform encryption mechanisms or frequency hopping technology.
