Bluetooth allows devices to communicate with each other wirelessly. That offers enormous possibilities. You can exchange files, print, listen to music, make wireless phone calls with a car kit, etc. Unfortunately, not every device is equipped with Bluetooth as standard. A Bluetooth dongle offers a solution. You can connect a computer or laptop to a Bluetooth dongle via a USB port. From that moment on, that computer can communicate with all other Bluetooth devices in the area. But there are also Bluetooth dongles that work without a USB port. Such as audio dongles in the car. This greatly expands the functionality of an old car radio.
History of Bluetooth
Bluetooth is a technology that was developed in the 1990s. There was a need for a wireless connection that made it possible to connect all kinds of mobile equipment, such as telephones, computers, headphones, printers and the like. Until then, this was done with cables, but that was fragile and clumsy. Even during the development of Bluetooth, it became clear that the applications were almost endless and that the technology had a lot of potential. When this was realized, almost all major equipment manufacturers supported the concept. That meant the definitive breakthrough of Bluetooth.
The technology itself was developed by the Dutchman Jaap Haartsen who was employed by the Swedish Ericsson at the Nieuw-Amsterdamsestraat in Emmen.
Bluetooth is radio
A Bluetooth connection uses a 2.4 Ghz radio signal. That frequency is reserved for that purpose worldwide. The signal is quite weak, but more than enough to connect devices within 10 meters of each other. Over time, several versions of Bluetooth have been developed. With some versions the transfer speed is higher and with other versions the distance to be bridged has been extended to up to 100 meters. Because it concerns radio signals, the devices do not have to be within sight of each other. A phone can remain in the bag and still connect to a car kit, audio system or another phone.
Technical background
The frequency on which Bluetooth works is the same as that used for cordless DECT telephones, garage door remote controls, baby monitors and the like. It is a frequency on which almost only devices communicate with each other. Because the signals are quite weak with a range of no more than 100 meters, there is always a channel available. Once two Bluetooth devices are connected to each other, they form a mini-network. Other nearby devices can join that mini-network. Such a network can contain more than 100 devices. They cannot all communicate with each other at the same time, but the connection is maintained.
Bluetooth and security
The technology behind Bluetooth connections has been deliberately kept fairly simple. Another condition is that energy consumption must be particularly low. This is necessary because in most cases the technology must be built into small devices that are powered by batteries. Despite this simple technology, the connections are well secured. The basic protocol supports encryption and identification. This is necessary, because it is not the intention that all equipment in a room is automatically linked together. A connection may only be established if two devices both have the same key. So they must 'know' each other.
Bluetooth competitors
Bluetooth is not the only technology to allow devices in close proximity to communicate with each other. One of the best known is the infrared connection technology IrDa. Bluetooth and IrDa each have their own characteristics. With IrDa, both devices must face each other. That is sometimes a disadvantage. But if there are many devices nearby, it is easier and above all much faster to connect than with Bluetooth. An advantage of Bluetooth is that the devices do not have to remain still during the connection.
Many applications of Bluetooth
Bluetooth has been used for about 20 years now. The number of applications is enormous. The technology is used to exchange files and images between devices and to transfer files from smartphones and tablets to computers. It is even possible to print files directly to a printer with Bluetooth. There are also many applications related to audio. Music on any device can be played on a Bluetooth speaker or headset via a Bluetooth connection. And Bluetooth is also used to control devices with wireless keyboards and mice.
Bluetooth dongle offers extra functionality
Due to the versatility of Bluetooth, its absence on devices is really seen as a loss. Fortunately, this can be resolved with a Bluetooth dongle. A Bluetooth dongle adds Bluetooth functionality to a device. But he does more. With a Bluetooth dongle in the car, in addition to the standard car kit functions, you can also control the sound system. So you are no longer bound to the limited music offering of the standard radio stations. With such a Bluetooth dongle, you can play your favorite radio stations from your smartphone on the car's sound system. The dongle clearly provides additional options here.
Large range of Bluetooth dongles
There are dozens of types of Bluetooth dongles available with a wide variety of functions. In many cases it concerns a Bluetooth dongle that is plugged into the USB port of a computer. This gives the computer Bluetooth functionality, but sometimes it goes further. Because there are also Bluetooth dongles that make an old computer suitable for WiFi. A Bluetooth dongle in the car almost always offers additional music functions in addition to car kit functions. However, there are also Bluetooth dongles for the car that, in addition to the music functions, are equipped with completely built-in navigation systems.
