Many people use Bluetooth technology to connect devices in their car, home and office. It is one of the most popular and prevalent technologies of the 21 century.
Unfortunately, many people don’t know anything about Bluetooth beyond how to use it. Bluetooth is a fascinating and helpful technology that people should know more about. Here are a few interesting facts about how what it really is and how it works.
What is Bluetooth?
Bluetooth is a wireless technology that can exchange data from different devices over short distances. It was invented by Ericsson in 1994 and has since become of the most widely used connectivity technologies around world. It is a relatively cheap technology to add to any device and doesn’t raise the cost of products very much.
This technology allows users to connect phones, speakers, headphones, tablets and even household products like lights and appliances to each other.
Bluetooth isn’t just for your house though.
Many vehicles, like the Jeep Renegade, use bluetooth technology to connect with your phone to allow for hands-free driving. This basically turns the Jeep’s speaker system into a large speaker phone that you can use to make calls on, listen to your playlists or even follow directions from your phone’s GPS.
How Does it Work?
Bluetooth works much like a radio set, transmitting at ultra-high frequencies between 2.4 and 2.485 gigahertz. These frequencies are reserved for industrial, medical and scientific devices so there is no chance of interference from television or radio sets.
When a Bluetooth-enabled device is turned on, it will automatically detect and connect with other devices that are enabled as well, as long as you have entered the passwords in the past. Devices that are enabled in the small area will not interfere with each other because there are 79 different channels that they use, so you can have a Bluetooth speaker, a Bluetooth cell phone and a Bluetooth-enabled tablet all on at the same time without worry.
Up to eight devices can be connected at a time. When they connect, one device takes the role of “master,” while the others are known as “slaves.” These form a small network known as a “piconet”.
Why is Bluetooth so Popular?
Bluetooth is so popular because it offers many great aspects that other technologies don’t.
First, the ease of connectivity makes it a clear choice for many people because you don’t have to be tech savvy in order to use a Bluetooth device. The technology also uses very low power, which enables Bluetooth sensors to run for months or even years on a small battery or other power supply.
For developers and hobbyists, Bluetooth devices are easy to install into new creations for very little cost, allowing them to invent new things with ease. This has led to the rise of the Internet of Things, where everyday objects are interconnected.
Bluetooth is a popular and cheap way to connect devices, and the technology should be around for a long time.
