What Is a Wireless Mouse?

A wireless mouse is a mouse that is directly connected to the host without a cable, and uses wireless technology to communicate with the computer, thereby eliminating the need for wires. Wireless communication methods are commonly used, including Bluetooth, Wi-Fi (IEEE 802.11), Infrared (IrDA), ZigBee (IEEE 802.15.4) and other wireless technology standards.

A wireless mouse is a cable that connects directly to

27Mhz Radio Frequence

27MHz RF refers to a technology using the 27 MHz ISM (Industrial, Scientific, Medical) radio frequency band, with an output power of <54dBuV / m. There are four global channels in this frequency band: two of which are used

Although the popularity of wireless mouse is not high, its development has a long history.

In 1984,

Wireless mouse latency and radiation

Delay and radiation problems were not a small problem in early wireless mice, but with the development of mouse chips and the application of wireless technology, the delay of mainstream wireless mice on the market is not obvious when used in general home or office To meet the needs of such users. But for professional gamers, probably most wireless mice are not suitable. In fact, all electronic products have radiation, but the radiation size is different. The mainstream wireless mouse on the market uses 2.4GHz wireless technology, and a small part uses Bluetooth wireless technology. However, on the issue of radiation, there is no specific measurement of the radiation data of wireless products. From a technical perspective, the radiation of these two wireless technologies is very small and can be ignored. So it seems unreasonable to reject a wireless mouse because of latency and radiation issues.

The difference between wireless mouse and wired

A wireless mouse needs to be powered by a battery, while a wired mouse can be powered by a computer, so the amount of battery power consumed by a wireless mouse can affect the cost of use for the user. Some wireless mice consume large amounts of power and require frequent battery replacement, which increases the cost of later use. However, from the perspective of the market, products with a battery life of about 3 months are a good choice, and the use of rechargeable batteries can be considered to save later costs. In addition, the battery inside the mouse will inevitably increase the weight of the mouse and affect the friction with the mouse pad. The wireless mouse on the market uses single and dual 5 AA batteries, as well as 7 AA batteries. Therefore, battery life and wireless mouse weight are indeed no small issues.

Wireless mouse gaming defect

The wireless mouse is not suitable for gaming, is this the reason? For some professional players or players with high requirements for game operation, wireless mouse has no advantage over wired mouse, mainly in terms of performance. However, there are also gaming mice specifically designed for gamers on the market, such as the Logitech G7. Whether a wireless mouse is suitable for playing games has a lot to do with game types and user needs. Therefore, it cannot be completely denied that wireless mice are not suitable for playing games, but in competitive games, professional players using wireless mice have not yet appeared.

Pairing problem

For a wireless mouse using 2.4GHz technology, the bit rate pairing process is required during the first use. Compared to a wired mouse, this process can seem cumbersome. So although the wireless mouse adapter also uses a USB interface, it must go through the pairing process before using it for the first time.

Wireless mouse has no price advantage

Early wireless mice, expensive prices were not acceptable to every consumer. However, with the increase of wireless mouse products, the low-end wireless mouse on the market has been on a par with the wired mouse. However, if the price of a wireless mouse is higher than that of a wired mouse of the same grade, the price factor is also the reason for not buying a wireless mouse.
