Bluetooth mouse is a wireless mouse, it is a wireless mouse.
< br \/ >
1, Wireless mouse now there are two main: 2.4G band, and Bluetooth, the two accept the encoding method is different.
< br \/ >
2, 2.4G communication distance is shorter than Bluetooth.
< br \/ >
3, generally do not provide adapters, but if it is to buy expensive models of mice will have, and some notebooks with Bluetooth function. The same performance of the mouse, Bluetooth is more expensive than 2.4G.
< br \/ >
4, as long as it is not too bad, there will generally be no loss of Zhen, but if there is a relatively large interference, or too far away, it will still exist.
< br \/ >
5, Bluetooth mouse fully reflects the portable characteristics of mobile office, effective range of up to 10 meters or more.
< br \/ >
6, the advantages and disadvantages of the Bluetooth mouse are reflected in the Bluetooth mouse does not need a receiver but requires the host to have a Bluetooth module, which is more suitable for laptop users with Bluetooth function, because the technology is relatively new, so the price will be higher, and because the target user is limited, the product style is less, and the selectivity is not strong.

7, the advantages and disadvantages of wireless mouse is the need to have a receiver, although the volume is not large but to occupy a USB interface, the advantage is that the technology is relatively mature, the price is cheaper than Bluetooth
< br \/ >
First, wireless mouse
< br \/ >
Wireless mouse refers to the mouse that is directly connected to the host computer without cable, and uses wireless technology to communicate with the computer, thus avoiding the bondage of wires. Wireless communication is usually adopted, including Bluetooth, Wi-Fi (IEEE 802.11), Infrared (IrDA), ZigBee (IEEE 802.15.4) and other wireless technology standards.

Ii. Disadvantages
< br \/ >
1. Delay and radiation
< br \/ >
Delay and radiation problems are not a small problem in the early wireless mouse, but with the development of mouse chips and the application of wireless technology, in general home or office use, the delay of the mainstream wireless mouse on the market is not obvious, which can meet the needs of such users. But for professional gamers, most wireless mice may not be suitable.
< br \/ >
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 number of Bluetooth wireless technology. However, on the issue of radiation, there is no specific measurement of the radiation data of wireless products, and from a technical point of view, the radiation of these two wireless technologies is small and negligible.
< br \/ >
Therefore, it seems unreasonable to reject wireless mice because of delay and radiation problems.
< br \/ >
2, and wired difference
< br \/ >
The wireless mouse needs to be powered by a battery, while the wired mouse can be powered by a computer, so the size of the battery consumption of the wireless mouse can affect the cost of use. Some wireless mice have a large power consumption, and the battery needs to be replaced frequently, which increases the cost of later use.
< br \/ >
However, from the market point of view, the battery life of about 3 months of products is a good choice, and can consider the use of rechargeable batteries to save later costs.
< br \/ >
In addition, after the battery is installed inside the mouse, it will inevitably increase the weight of the mouse and affect the friction with the mouse pad. The wireless mouse on the market uses a single and dual 5 battery, and also uses a 7 battery. So, battery life and wireless mouse weight is really not a small issue.
< br \/ >
3. Game defects
< br \/ >
Wireless mouse is not suitable for playing games, this reason is right? For some professional players or players with high requirements for game operation, wireless mice do not have advantages compared with wired mice, mainly in terms of performance.
< br \/ >
However, there are also gaming mice on the market that are specifically designed for gamers, such as the Logitech G7. Whether the wireless mouse is suitable for playing games is actually related to the type of game and user needs. Therefore, it is not completely denied that the wireless mouse is not suitable for playing games, but in the competitive game competition, the professional player who uses the wireless mouse has not appeared.
< br \/ >
4. Pairing problems
< br \/ >
For wireless mice using 2.4GHz technology, the rate pairing process is required when first used. Compared to a wired mouse, this process can seem cumbersome. Therefore, although the wireless mouse adapter also uses a USB interface, it must go through the pairing process before it is used for the first time.
< br \/ >
5, the price has no advantage
< br \/ >
Early wireless mouse, the high price is not acceptable to every consumer. However, with the increase of wireless mouse products, low-end wireless mice on the market have been on an equal footing with wired mice. 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 not to buy a wireless mouse.
