Detailed explanation-1: -Bluetooth and Wi-Fi are both wireless networking technologies. They transmit information via radio signals broadcast through the air rather than over wires, allowing devices to communicate with each other and share information.
Detailed explanation-2: -Wi-Fi is similar to Bluetooth in that it also uses radio waves for high-speed data transfer over short distances without the need for a wire connection.
Detailed explanation-3: -Wireless technology uses radiofrequency energy, which is a type of non-ionizing radiation. Government agencies set safety guidelines that limit your exposure to radiofrequency energy. Scientists continue to study the long-term health effects from exposure to low-levels of radiofrequency energy.
Detailed explanation-4: -Wi-Fi and Bluetooth both occupy a section of the 2.4 GHz ISM band that is 83 MHz-wide. Bluetooth uses Frequency Hopping Spread Spectrum (FHSS) and is allowed to hop between 79 different 1 MHz-wide channels in this band.
