Bluetooth: BrandsMart Answers Lab

Is there anything worse than cables?  Yes, there is….

How about adding even more cables with your new electronic purchase? That’s worse.

Computers, printers, cell phones, headsets, TVs, DVD players, cameras…you know exactly how annoying all those wires can be.  Thankfully, there is a way to bring electronic gadgets together to exchange data without any wires at all…

Let’s talk about Bluetooth®

Bluetooth is short-range wireless (radio wave) technology designed for connecting to and communicating between paired devices.  Bluetooth technology provides a simple way for wireless items to link together and share voice, data, music, photos, videos, and other information.  These electronic gadgets have built-in radio antennas so they can send and receive signals to other Bluetooth gadgets within a distance of approximately 30 feet.

Why is Bluetooth called Bluetooth?

It’s a pretty funny name, but it makes more sense when you know it comes from the Danish King, Harold Blatand (pronounced BLA-TEN’D)who had an amazing way of bringing people and territory’s together.

The English translation of “Blatand (pronounced BLA-TEN’D)- you guessed it, Bluetooth.

How does Bluetooth work? 

Well, Bluetooth devices have a tiny radio transmitter that can send information over short distances, normally within thirty feet from your device.  The two devices you want to pair are both sending out signals, and when they are within range of each other, you can pair them together.  Once paired?  Voila! Your phone, speakers, car, and computer – can now share music, voice, data, photos, videos, and more.

Advantages of Bluetooth

Typically, Bluetooth might be used to make hands free calls on a headset in the office or in your car, listen to music through speakers or headphones, link a mouse or keyboard to laptop or PC, or print a document down the hall. Most of your wireless gadgets now come with Bluetooth technology, including all the top-selling Smartphones, PCs and tablets.

Bluetooth is an excellent method for tethering.  Similar to Wi-Fi, you can wirelessly connect multiple devices.  But since Bluetooth is specifically designed for mobile use, it generally consumes less power and is easier on your battery.  Additionally, Bluetooth’s short-range transmitters are theoretically more secure than wireless networks that operate over longer ranges, such as Wi-Fi.

Even so, Bluetooth is not considered competition for Wi-Fi, which is generally a replacement for wired local area networking.  Bluetooth, on the other hand, is more commonly used as a replacement for cables between individual devices.

Originally intended to act as a wireless replacement for cables on phones, keyboards, headsets, and mice, Bluetooth wireless technology now extends far beyond that.  Bluetooth is built into billions of products from cars and mobile phones to medical devices and computers to forks and toothbrushes.  In the Healthcare sector alone there are already 40 million+ Bluetooth-enabled professional and home devices such as stethoscopes, inhalers, glucose monitors, scales, pulse and heart rate monitors.

The applications for Bluetooth are endless, and this technology is creating opportunities for companies to develop solutions that improve consumers’ lives.  In the near future, motorists will have the ability to monitor important real-time information like traffic, vehicle diagnostics, and even driver health.

Most Bluetooth enabled devices are easy to pair.  To connect, you must first turn on your device’s Bluetooth.  Then, the first time you use a new Bluetooth device, you need to “pair” it so that both devices know how to connect securely to each other.  In many instances it is merely a press of a button.  After that, they connect automatically and you are free to enjoy a hands-free life.
