Wireless Mouse Development Technology Is Mature

To be precise, "Bluetooth" technology is a standard developed by a private non-profit organization Special Interest Group (SIG) established in September 1998. The SIG organization itself does not manufacture, produce or sell any Bluetooth devices. Why is it said that "Bluetooth" itself is a standard, not a frequency (RF)? Because the frequency band used by Bluetooth is the same as 2.4G RF, both are free and unlicensed 2.4-2.485GHz ISM (industrial, scientific, and medical) in most countries. However, Bluetooth technology adds self-defense to common 2.4G wireless technology. Adapt to frequency modulation technology (adaptive frequency hopping, AFM), realize full duplex transmission mode, and realize 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 on the 79 sub-bands divided by 1Mhz.

After years of development, Bluetooth technology has evolved from the original 1.0 standard to the current 5.0 standard (which also includes three standards 1.1, 1.2 and 2.0). The focus of Bluetooth 5.0 is to increase the transmission range to 4 times (up to 300 meters in theory) and 2 times the transmission speed (2Mbps), while the broadcast data transmission volume is 8 times that of the original Bluetooth 4.2 standard.
