Which communication technology allows devices to communicate over a range of approximately 30 feet?

Bluetooth is a short-range wireless communication technology designed for exchanging data between devices over a relatively short distance, typically around 30 feet (or 10 meters). This capability makes it ideal for connecting devices like smartphones, headphones, speakers, and other peripherals without the need for physical cables.

Bluetooth works effectively within this limited range, enabling users to maintain a stable connection while moving around within that distance. Its low power consumption is also a significant advantage, making it suitable for battery-operated devices. In contrast, other technologies like GPS, cellular, and Wi-Fi operate over much greater distances or serve different purposes, such as location tracking or providing high-speed internet access, which is why they are not suitable for this specific question regarding a communication range of approximately 30 feet.
