Is Bluetooth or wifi better in wireless mouse?

The wired mouse uses wireless technology to communicate with the computer, thus eliminating the bondage of wires. Commonly used wireless communication methods include Bluetooth, Wi-Fi (IEEE 802. 1 1), infrared (IrDA), ZigBee (IEEE 802. 15.4) and other wireless technical standards, but for the current mainstream wireless mouse, there are only 27Mhz, 2.4G and Bluetooth wireless mouse *. 2.4Ghz non-networked solution "2.4Ghz non-networked solution" is also commonly known as 2.4G wireless network technology. Its advantage is that it solves the shortcomings of high power at 27Mhz, short transmission distance and mutual interference of similar products. The reason why the 2.4G wireless technology is "2.4G" instead of "2.5G" is that the frequency used by this technology is 2.4-2.485GHz ISM wireless band, which is used for free without authorization in most countries in the world, clearing the biggest obstacle for the popularization of products. To be precise, Bluetooth technology is a standard formulated by a non-governmental non-profit organization-Special Interest Group (SIG for short), which was established in September 1998. SIG itself does not manufacture, produce or sell any Bluetooth devices. Why is Bluetooth itself a standard, not a frequency (RF)? Because the frequency band used by Bluetooth is the same as that of 2.4G RF, Bluetooth technology adds adaptive frequency hopping (AFM) to ordinary 2.4G wireless technology between 2.4-2.485GHz ISM (industry, science and medicine) which is free and unauthorized in most countries, realizing full-duplex transmission mode and automatic frequency modulation of 1600 times per second. In addition, this technology enables the receiver and transmitter of Bluetooth devices to pair with each other in 79 subbands with an interval of 1Mhz. After years of development, Bluetooth technology has developed from the original 1.0 standard to the current 2. 1 standard (including 1. 1, 1.2 and 2.0). The new generation standards have improved the data transmission rate, reduced the power consumption and standardized the lower version on the basis of the original standards. Perhaps because Bluetooth version 2. 1 was released late (SIG released Bluetooth version 2. 1 on August, 2007), at present, the top Bluetooth mouse and keyboard products of Microsoft and Logitech only support 2.0 specification, including Microsoft Multimedia Entertainment Suite 8000 and Logitech diNovo Edge keyboard.
