Which of these technologies allows wireless connectivity in a Personal Area Network

Bluetooth is the technology that enables wireless connectivity in a Personal Area Network (PAN). It uses radio waves to transmit data over short distances between devices such as smartphones, laptops, headphones, and smartwatches. Bluetooth technology operates within a limited range, typically up to 30 feet (10 meters), making it ideal for connecting devices within a personal space like a room or a car. Bluetooth-enabled devices communicate with each other by pairing and creating a secure wireless connection, allowing users to transfer data, stream audio, and make hands-free calls. Therefore, out of the given options, Bluetooth is the technology that allows wireless connectivity in a Personal Area Network.
