Bluetooth

Bluetooth is a technology named after a Danish king, Harald Bluetooth, who consolidated Denmark and areas in Norway during the 900s. Companies in Denmark and Norway have largely influenced the global telecommunications industry. The name was given to the technology in the effort to manifest such influence.

Bluetooth is a data transmission technology that does not require large amounts of electrical power. It does not demand user control to transmit data.  Bluetooth can limit transmission power to at least 1 miliwatt making it an ideal transmission technology for mobile battery operated electronic devices. Bluetooth devices recognize each other’s presence and they automatically communicate with each other without requiring user input.

There are only 2 things that the Bluetooth technology relies on. One of them is the radio frequency technology. The second one is the protocol software that will enable transmission of data between devices.

Devices that are Bluetooth capable can transmit data even when the other devices are not within sight of the sending or receiving user. A Bluetooth device will be able to communicate with another Bluetooth capable device for transfers even if they are located in separate rooms within a building.

The transmission of data is performed among different devices around specified rules and particular amount of data. Bluetooth capable devices can communicate with the least interference from other capable devices.

The principal transmission system in using the technology is low energy radio waves. The range of frequency goes from 2.402 GHz to 2.480. The international agreement for medical, industrial and scientific devices or ISM specifically reserved such frequency range.

Bluetooth is not only capable of a one-on-one data transfer. The technology can support communication up to 8 devices that are within the transmission radius. Simultaneous transfers among these devices can happen.

The most randomly chosen frequencies per second of transmission is 1600 different frequencies. This allows the Bluetooth devices to minimize the use of the same frequency. This will also decrease the interference time when a Bluetooth device overlaps with another device that is using same frequency.
