What is Bluetooth and How Does It Work?
Bluetooth Smart Technology is a wireless communications system intended to replace the cables connecting many types of devices, from mobile phones and headsets to hear monitors and medical equipment. Bluetooth is a wireless short-range communications technology standard found in millions of products we use every day – including headsets, smartphones, laptops and portable speakers. A product with Bluetooth technology, such as a Bluetooth headset, has a tiny computer chip inside that contains the Bluetooth radio, and software that makes connectivity between devices possible.
So when Bluetooth-enabled products, such as a cell phone and headphones, are in close proximity to each other, they connect, or pair. A single Bluetooth headset can even connect to multiple devices at the same time. This enables you to talk on the phone or listen to music without the bother of wires or cords. Whether you want to stay safe on the road.
What is The Range of a Bluetooth Device?
In contrast, class 2 devices transmit at 2.5 mW with a range of approximately 10 meters or 32 feet. Class 2 devices are the most common Bluetooth transmitters for their fair range with less power requirements than class 1 devices. Most mobile phones and Bluetooth headsets are class 2 devices.
What is a Bluetooth Headset?
A Bluetooth headset is a great convenience—and not just for people who need to gesture while they talk. Rushing through an airport to catch a flight? A hands-free Bluetooth headset lets you take calls without breaking your stride or setting down your carry-on luggage.
What is the use of Bluetooth Dongle?
A personal computer that does not have embedded Bluetooth can use a Bluetooth adapter that enables the PC to communicate with Bluetooth devices. While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB "dongle."
