What is a wireless mouse?
A wireless mouse refers to a mouse that is directly connected to the host without a cable, and uses wireless technology to communicate with the computer, thereby saving the shackles of wires. Usually wireless communication methods are used, including multiple wireless technology standards such as Bluetooth, Wi-Fi (IEEE 802.11), Infrared (IrDA), ZigBee (IEEE 802.15.4), etc.
Bluetooth connection technology
“2.4Ghz non-networking solution” is what we commonly call 2.4G wireless network technology. Its advantage is that it solves the shortcomings of 27Mhz high power, short transmission distance, and mutual interference of similar products. The reason why 2.4G wireless technology is “2.4G” instead of “2.5G” is because the frequency used by the technology is the 2.4-2.485GHz ISM wireless frequency band, which is free for use in most countries around the world. This is a product The popularity of China has cleared the biggest obstacle.
The 5.8GHz frequency band is an open ISM frequency band that is higher than the 2.4GHZ frequency and provides three 100MHz U-NII (national information infrastructure without license) frequency bands for high-speed wireless data communication. These three 100MHz frequency bands are: 1. 5.15～5.25GHz, which stipulates that its EIRP is not greater than 23dBm for indoor wireless communication; 2. 5.25～5.35GHz, which stipulates that its EIRP is not greater than 30dBm, which is suitable for medium-distance communication. 3. 5.725 ~ 5.825 GHz, usually people choose 5.725 ~ 5.825 GHz for broadband wireless access in the community, in order to obtain a better price-performance ratio.
