The technology that has the smallest maximum range for data transmission between devices is near-field communication (NFC). NFC is a short-range wireless technology that enables two devices to communicate when they are in close proximity, usually within a few centimeters. NFC is commonly used for contactless payments, smart cards, and device pairing. According to the Bluetooth Technology Website1, the effective range of NFC is less than a meter, while the other technologies have much longer ranges. Wi-Fi can reach up to 100 meters indoors and 300 meters outdoors2. Bluetooth can reach up to 800 feet with Bluetooth 5.0 specification3. Long-term evolution (LTE) can reach up to several kilometers depending on the cell tower and the device4.
