Bluetooth Question & Answers

June 5, 2021 By WatElectronics

This article lists 100 Bluetooth MCQs for engineering students. All the Modulation Questions & Answers given below include a solution and link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on Bluetooth topic which is core in Electronics & Communication Engineering.

Bluetooth technology is also a wireless LAN technology, where we connect the devices such as telephones, printers, computers, laptops, cameras, etc within short distances. The Bluetooth uses ISM (Industrial, Scientific, Medical) radio frequency band for communicating with other devices.

Bluetooth was developed by a telecommunication company ERICSSON in 1994 and was initially called “Short Link Radio Technology” until 1997 later it got the name Bluetooth. It is a low-power-consuming technology and it operates within a short range and provides a wireless connection to mobile phones, computers, and all electronic devices which are Bluetooth enabled.

There can be an N number of devices that are not Bluetooth enable but the Bluetooth demands that each of the devices should be Bluetooth enabled.
