What is Bluetooth?
Bluetooth is a global standard for a small radio module that is plugged into computers, printers, mobile phones, and other devices. A Bluetooth radio is designed to replace cables by taking the information normally carried by the cable and transmitting it over radio frequency in the unlicensed 2.4 GHz frequencies to a receiver Bluetooth radio chip.
Bluetooth® is a wireless technology used to communicate from one device to another in a small area – usually less than 30 feet. Think of it as an invisible wire. A Bluetooth®-enabled cell phone can send a call to an earpiece or a hands-free system, allowing you to communicate without holding the phone. When using a hands-free system, the phone can be anywhere in the car, it does not have to be visible or out in the open.
Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmissions over short distances from fixed and/or mobile devices, creating wireless personal area networks (PANs). The intent behind the development of Bluetooth was the creation of a single digital wireless protocol, capable of connecting multiple devices and overcoming issues arising from synchronization of these devices. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, GPS receivers, digital cameras, and video game consoles over a secure, globally unlicensed Industrial, Scientific, and Medical (ISM) 2.4 GHz short-range radio frequency bandwidth.
