How wireless mouse works
It mainly relies on Bluetooth technology to transmit signals.
DRF(Digital radio frequency) technology can provide sufficient bandwidth for short-range communication, very suitable for the use of peripheral devices such as mouse and keyboard, its principle is very simple, the mouse part of the work is the same as the traditional mouse, and then use the wireless transmitter to move the mouse on the x or Y axis. The information of button pressing or lifting is converted into a wireless signal and sent out, and the wireless receiver receives the signal and decodes it to the host, and the driver informs the operating system of the mouse action to move the mouse pointer in which direction or what instruction to execute.
With high frequency radio (RF) technology, it can be used in any location, almost unaffected by obstacles, as long as it is within a limited distance. Generally, the transmission distance is 10 to 20 meters, which is enough for users to use.
The biggest feature of the radio is that it can carry out 360-degree radio frequency remote control, and the power consumption is low, and it has the trigger work standby sleep. The receiver of the wireless device has a built-in receiver, and the transmitter is installed on the device port of the host, which will not affect the appearance of the product.
The interface of the radio receiver itself is USB or PS2, which can be taken from the PS\/2 interface of the computer without the need for additional batteries. It has dual or multi-band, if there are multiple wireless devices, can be managed through this receiver, the keyboard operating frequency generally occupies channel 1 (such as: 27.185M and 27.035M), the mouse operating frequency occupies channel 2 (such as: 27.085M and 27.135M), low interference between mouse and keyboard or multiple mice when working, and will not affect digital wireless devices such as wireless phones.
Wireless mouse has energy-saving mode, the use of low-power chip, there are multiple power-saving measures, in the running mode LED flashing speed is 1500 times \/s, and in the most power-saving mode blinking speed is only 2 times \/s, move the mouse or press the mouse button, the mouse quickly returned to normal mode.
In addition, some mice support manual wake up energy-saving technology, on both sides of the mouse equipped with conductive rubber, through the touch switch on the mouse to control the power at will, when the user's hand left the mouse for 2 seconds, the mouse immediately into the sleep state, the user needs to use the mouse, as long as the hand touches the conductive rubber, the mouse is immediately activated, the efficiency is higher than the multiple energy-saving mode. All of the above methods extend the battery life, which is close to the level of the general wireless mouse, about three to six months. Of course, its power consumption is as small as that of a traditional mouse.
The principle of wireless mouse is to wirelessly connect with the computer through Bluetooth or RF signals to achieve the transmission of mouse movement signals to the computer, thereby controlling the movement of the cursor.
The wireless mouse has a transmitter inside, which will receive the signal sent by the computer and convert it into a motion control signal, and send it to the mouse sensor for display processing, and finally display the cursor shift caused by the control signal on the computer screen. The core of the wireless mouse is the use of wireless communication technology, which effectively reduces the inconvenience caused by distance and wire, and is more convenient and flexible to use.
The principle of wireless mouse is to communicate with the computer through wireless signals.
It is based on radio technology, through the transmitter inside the mouse to convert the movement and click information into electrical signals, and then through the wireless signal to the receiver.
In this way, the computer can receive the signal of the mouse and react accordingly, so as to achieve the control of the computer. The development of wireless mouse is inseparable from the continuous development of wireless technology, and now the mainstream wireless mouse communication methods include wireless Bluetooth and radio frequency technology, as well as some traditional wireless mice using infrared technology.
In addition, some intelligent wireless mice can also achieve more human-computer interaction functions through touch technology, acceleration sensors, etc.
The principle of wireless mouse is based on radio communication technology.
The mouse communicates with the computer through wireless signals such as infrared or Bluetooth to realize the movement of the cursor and the operation of keys.
Wireless mice use radio technology to send signals to the receiver, and then communicate with the computer through the receiver, with higher flexibility and portability than wired mice. The main advantage of the wireless mouse is that it does not need to use the mouse cable and can move freely, making it more convenient to use.
At the same time, wireless mice can also transmit farther than wired mice. The disadvantage of the wireless mouse is that the battery needs to be replaced or charged regularly, and the signal is unstable or the delay is large.
The wireless mouse is composed of a mouse and Bluetooth components, through the Bluetooth transmitter through USB access to the computer, through the computer driver to recognize Bluetooth, send signals to connect to the mouse, and then the mouse can work as normal as the wired one.

The specific principles are as follows:

1. Bluetooth technology: Wireless mouse built-in Bluetooth chip, using 2.4GHz frequency band for communication. When the mouse is connected to the computer, the Bluetooth chip sends a Bluetooth signal, which is received through the Bluetooth adapter or the computer with built-in Bluetooth function and converted into instructions. This allows the mouse to operate on the computer.

2. Radio frequency technology: The wireless mouse has a built-in radio frequency transceiver (USB receiver), and also uses the 2.4GHz band for communication. When the mouse is connected to the computer, the wireless transceiver communicates with the computer through the USB port, sends the signal sent by the mouse to the computer, and the computer analyzes and responds to the command of the mouse after receiving the signal.

No matter which technology is used, wireless mice need batteries to ensure the transmission and reception of signals. Generally, wireless mice use AAA batteries or AA batteries.
How wireless mouse works: When the mouse moves, the optical sensor continuously collects every point on the desktop, sends the collected point to the master chip for memory and compares the bit difference of the next point. The master chip converts the displacement signal compared into the corresponding interface information through RF IC to make wireless carrier signal and transmit it through the wire, and the receiver receives the corresponding wireless carrier signal through the antenna. After RF IC modulation detection of the corresponding interface information to the USB master chip, the master chip is converted into USB signal, and then transmitted to the computer through the USB cable, so as to achieve the cursor up and down movement.
The principle of wireless mouse is to use radio frequency or Bluetooth technology to communicate wirelessly with the computer, so as to achieve wireless control of the mouse. Wireless mouse has a built-in chip that can transmit wireless signals and communicate with the computer. The chip can send signals to the computer, and then receive the returned data from the computer. In this way, the mouse can communicate with the computer directly through wireless means, and the wireless control of the mouse is realized.
Wireless mice are relatively convenient to use, and they no longer have to be entangled in the limited space between the keyboard and the computer. However, it should be noted that its power supply is a battery, and the efficiency of power use is lower than that of a wired mouse, and the battery needs to be replaced in time.
At the same time, due to the principle of wireless communication, sometimes wireless mice will be affected by signal interference, which affects its accuracy and stability.
The wireless mouse communicates and operates with the computer through wireless signals, and its principle is to transmit data using infrared or radio frequency signals.
A miniature antenna inside the wireless mouse converts the data into a wireless signal, which is transmitted to the computer through the wireless receiver, and then transmitted to the computer through the USB interface.
Therefore, the principle of wireless mouse is to use wireless technology to wirelessly transmit data to the computer to achieve remote control of the computer.
The emergence of wireless mouse is convenient for people to use, avoiding the cable problems of traditional wired mouse and the limitation of use distance. At the same time, the realization of wireless mouse is inseparable from the development of wireless communication technology, which is an important application and development direction of wireless information transmission technology in the field of personal computers.
The principle of a wireless mouse is to connect through wireless signals.
Because the wireless mouse does not have the cables of a traditional mouse, it does not need to be connected to the computer by cable.
Wireless mouse uses Bluetooth technology or RF technology to connect to the computer.
By installing the corresponding driver, the wireless mouse can be connected and communicated with the computer, so as to achieve the function of the mouse.
Compared with wired mice, wireless mice are more flexible and easy to carry.
It should be noted that the wireless mouse needs to install the corresponding battery when it is used, and to ensure that the battery is sufficient, so as not to affect the work of the wireless mouse.
A wireless mouse is a computer peripheral that uses wireless signals to transmit data. Usually, the wireless mouse is connected to the computer through a wireless receiver, which can be connected to the USB port of the computer or connected to Bluetooth.
