Wireless mouse refers to the mouse directly connects to the host without cable. It generally applies 27M, 2.4G and Bluetooth technology to achieve wireless communications with the host. Since it came into being in 1968, mouse has experienced nearly 40 years of evolution and development. For nearly 10 years, along with the popularity of consumer computer, mouse has also been tremendous improved: from the early mechanical wheel mouse to mainstream 2.4G optical mouse and then to in high-end laser mouse ... every changes of the mouse have brought pleasure for users. In addition, as people increasingly improve requirements to office environment and convenient operation, the popularity of wireless mouse is mentioned on agenda.
2.4Ghz Non-networking Solutions
"2.4Ghz non-networking solution" is commonly called 2.4G wireless network technology. The advantage is that it has avoided shortcomings of 27Mhz high power, short transmission distance, similar products prone to interfere with each other, etc. The reason 2.4G rather than 2.5G is that the frequency of using this technology is a 2.4-2.485GHz ISM wireless band, which is license-free and free use in most countries around the world. That clears the biggest obstacle for the popularity of the products.
Shortcomings of Wireless Mouse
1. There is a maximum difference between the wireless mouse and wired mouse: wireless mouse needs to be powered by a battery while wired mouse can be powered through the computer. So the battery power consumption of the wireless mouse may affect the user's cost problem, which is also a common problem users response most. Some wireless mice suffering big power consumption need to replace batteries frequently, which increases the later use cost a lot. But from the market point, the battery with life about 3 months is a good choice, and users can consider using rechargeable batteries to save the later cost. In addition, mouse with batteries inside is bound to be heavier, which affects mouse pad friction. There are wireless mice on the market using single and double 5th battery and 7th battery. Thus, the battery life and the wireless mouse weight are not small problems.
2. It is necessary to go through the code rate pairing process of the wireless mouse using 2.4G wireless mouse technology during the first use. For some users, compared to a wired mouse, this process may seem too much trouble. So although the wireless mouse adapter also uses the USB interface, it is also necessary to go through the pairing process before the first use.
3. High prices of early wireless mouse are not acceptable to every consumer, but with the increase in wireless mouse products, low-end wireless mouse on the market has had an equal footing with the wired mouse. However, if compared with the same grade wired mouse, wireless mouse may have a higher price. So the price factor is also a reason why consumers do not buy a wireless mouse.
