What Is a 2.4 GHz Wireless Audio Signal?

2.4ghz wireless technology is a short-range wireless transmission technology for open source use. 2.4GHz refers to a working frequency band. 2.4GHz ISM (Industry Science Medicine) is a wireless frequency band used in the world. Bluetooth technology works in this frequency band. Working in the 2.4GHz frequency band can obtain a wider range of use. And stronger anti-interference ability, widely used in home and commercial fields. Technology for short-range wireless transmission and conduction.

In order to realize the automation control of industry, home and building, liberate human beings from the wired environment, with the goal of replacing cables as a short-range wireless communication technology standard for wireless personal area network (WPAN) It has developed rapidly. Typical technical standards include Bluetooth, ZigBee, wireless USB, and wireless LAN Wi-Fi. As people enjoy convenience and speed, the electromagnetic compatibility problems of these technologies are increasingly prominent. As these technologies have selected the 2.4GHz (2.4 to 2.483GHz) ISM band, coupled with interference sources such as cordless phones and microwave ovens, this band has become increasingly crowded.
