Technology is created to make our lives more efficient, safer, and easy to use. Bluetooth has become the norm for connectivity in recent years and it exists in most of our portable electronics today. Bluetooth is created to connect two separate devices over a short range of less than 30 feet apart. But there are some facts that you may not know about Bluetooth, so let us explore together the following interesting points below.
- Bluetooth is named after a Viking: Intel mobile computing engineer Jim Kardach was reading “The Long Ships” in which Harald “Blåtand” (Anglicized word for Bluetooth) Gormsson, King of Denmark and Norway was featured in it. The King was responsible for bringing the wild Viking tribes into Denmark. Therefore, Jim chose Bluetooth as a name for this techonology, for bringing different devices and connect them together.
- Bluetooth Special Interest Group (SIG): In 1988, through the initiative of Jim Kardach, SIG was formed. It featured four prominent companies at that time: Ericsson, Intel, Nokia, and Toshiba. Since then, many companies have joined this group.
- Bluetooth logo itself is made up of runes for Harold Bluetooth initials: H.B. (see picture below).
- Bluetooth uses master and slave relationships to connect devices: One master can have as much as 7 slaves. For example, your computer can connect to its counterparts such as mouse, wireless keyboard, printer and so forth. Moreover, the master and slave relationship can also switch roles as well.
- How does Bluetooth connect? Bluetooth uses 79 different ultra-high radio frequencies or called UHF, between 2.4 GHz and 2.48GHz. Each second the master scans the radio frequencies for the salve’s frequency. Once matched, both connections will connect to each other.
Below are some other different Bluetooth applications used today.
- Remote Controls. Most of the remote controls used today use infrared (IR) transmitter to relay command from the controller to the designated device such as television sets, air condition units. However, with Bluetooth remotes, the user does not have to be directly line in sight of the device to control or send the desired command. These can be used in situations such as smart homes or air condition units.
- Bluetooth Tethering. You can also share your wireless hotspot or mobile data using Bluetooth if you have android smart phone with your tablet, or laptop devices.
- Transferring Data. Users can now transfer data between laptop, tablet, or smartphone using Bluetooth connection without the use of cables.
- Smart Home Applications. Often users encounter annoying walls between rooms and cables on the floor everywhere to connect devices. Now with the use of Bluetooth, users can set up Bluetooth stations throughout their home for smart home applications such as multiroom setups (one room playing radio music, while watching a movie in another). Other applications include lock and unlock front door with Bluetooth application, turning lights on and off, temperature settings, etc.
- Bluetooth and Vehicles: New vehicles are now equipped with Bluetooth technology to connect smartphones, tablets, or other devices to the vehicle itself without all the annoying cables. Eg: GPS apps or music.
Another important use of the Bluetooth technology is applied in our Baby Car Safe product. With this application, users can now pair our product with the vehicle to show important vehicle dynamics and information. Let us make use of new technology so that we can make your lives more efficient, safer, and less hassle free.
