Wireless communication is becoming integral to electronics as more and more consumers demand the ability to send and receive data without being tied down with plugs and cables. Among the most popular wireless communication protocols is Bluetooth, which has the versatility to find homes in a range of applications.
Among many other apps, Bluetooth is embedded in cars so that users can play their favorite music from a smartphone on the car stereo. The new field of smart-home security utilizes Bluetooth to allow individuals to perform tasks like locking and unlocking their front door with their phone. Bluetooth can also be used to send files between a tablet and a computer, send updates from a fitness tracker to a computer or phone, and much more.
