Explanation:
Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions in the ISM bank from 2400-2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.
Wifi can transmit at frequencies of 2.4 GHz or 5 GHz. This frequency is much higher than the frequencies used for cellular phones, walkie-talkies and televisions. Increase the frequency of the signal can carry more data.
A wireless local area network (WLAN) links two or more devices using some wireless distribution method. Most modern WLANs are based on IEEE 802.11 standards, marketed under the Wi-fi brand name.
Bluetooth devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, so long as the received power is high enough.
