Bluetooth is one of those terms you often hear in conjunction with wireless Internet. But how does it actually work?
Typically speaking, there are several ways to connect devices: cables, wires, Ethernet, wi-fi, infrared (remote controls) and Bluetooth. You might think of Bluetooth as the earpiece device you see people walking around with. The device itself isn’t called Bluetooth. Rather, the technology it’s using is called Bluetooth.
Bluetooth capability is standard on most phones, computers, and laptops. You’ll also occasionally find it on cameras, printers, and even kitchen appliances.
How Bluetooth works
Wi-fi and Bluetooth are perhaps the most similar. However, the difference between them is that wi-fi is mainly for computers on a network. Bluetooth is used for smaller-scale, cross-device information transfers in a tight area.
Bluetooth uses radio waves for signaling and to locate other devices. It’s like a walkie-talkie, but one that doesn’t strain your battery too much. When devices are connected but not actively transmitting a lot of information (idle), the signal downgrades to preserve the battery of each device.
Bluetooth can sync up to eight devices at once. So if you’re wanting to listen to your wireless speakers, play on your smartphone and laptop, and juggle bananas while reading the New York Times on your iPad, you can also do that while UStreaming your dog’s magic show. It’s the American dream!
Bluetooth security with wireless devices
With any technology come some security concerns. There’s always a way to get around things. In the case of Bluetooth, it’s called Bluejacking. If you have a cellphone with Bluetooth, for example, you can send other Bluetooth users around you a message. You won’t know who it’s going to, but your phone can pick up the Bluetooth signals of other devices in your area. They won’t know who sent it, but you can see who checks their phone and know who it is.
Tying Bluetooth back to wireless Internet
So what do the two technologies have in common? Well first of all, Bluetooth is a wireless technology. Plus, the devices that use it are wireless.
Bluetooth is becoming a standard feature in many wireless devices these days. The more we depend on wireless signaling, the more devices we’ll see with Bluetooth capability. Case and point: Bluetooth refrigerators.
