Detailed explanation-1: -Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs).
Detailed explanation-2: -Short-range wireless technologies include Bluetooth, Wi-Fi, near-field communication (NFC), LPWAN, ultra-wideband (UWB) and IEEE 802.15. 4. They are implemented by chips fabricated as RF CMOS integrated circuit (RF circuit).
Detailed explanation-3: -Short Range Devices (SRD) are radio devices that offer a low risk of interference with other radio services, usually because their transmitted power, and hence their range, is low.
Detailed explanation-4: -Bluetooth wireless uses radio waves on a particular frequency (2.4 GHz) for data transmission from device to device. > The effective range for infrared wireless is very short-generally no more than five meters, and often closer to one meter.
Detailed explanation-5: -Near Field Communication (NFC) NFC is a new short-distance wireless communication technology based on Radio Frequency Identification technology (RFID), whose operating frequency is 13.56MHz.
