What is Bluetooth?
Bluetooth is an Anglicized form of a tenth century Danish king’s name Blatand, who was recognized for his role in joining several Danish tribes into a single kingdom. The technology is already present in billions of devices, despite being discovered about 2 decades ago. Generally, Bluetooth technology is a standard that transmits data over short distances using ultrahigh frequency (UHF) radio waves.
The technology can transmit data for a range of up to about 100 meters, and is regarded for its robustness, low cost, and low power consumption. Furthermore, the technology can handle both data and voice transmissions.
How Bluetooth Works
Bluetooth technology was designed to exchange data between fixed and mobile devices over short distances. This is achieved by creating a personal area network (PAN), also known as a piconet. A single piconet can have up to seven Bluetooth devices. Bluetooth operates on a frequency of between 2.402 GHz and 2.480 GHz.
The Bluetooth technology uses UHF radio waves. Bluetooth further relies on frequency-hopping spread spectrum, which divides the data being transmitted up to among 79 frequencies. This technology reduces chances of interference, and the improves the likelihood of the data arriving at the destination quickly and without distortion.
Furthermore, this frequency-hopping technology means that the signals sent through Bluetooth can share frequency bands with other transmissions without much interference. In fact, Bluetooth is designed to operate in noisy radio frequency environments, which makes it great for areas where other wireless transmission technologies would fail due to interference.
Factors Affecting Bluetooth Transmissions
For the Bluetooth technology to work, each of the devices has to have a Bluetooth transreceiver microchip. A visual line of sight is not necessary since the technology uses broadcast radio signals. Finally, the transmission range varies with the category in which the device with the technology belongs. More specifically, class 1 devices can transmit for a range of 100 m; while class 2 can transmit for 10 m as class 3 transmit for about 1 m.
The Future of Bluetooth
Experts in wireless technology think that the full potential of Bluetooth technology is yet to be exploited. Although currently confined mostly to communication, entertainment, and computing devices, the technology is likely to be more prevalent in more household devices.
Additionally, the use of Bluetooth technology will allow the use of wireless devices such as remote controls more sophisticated. This will be especially useful as more devices, particularly entertainment devices such as televisions offer access to the Internet. In such cases, wireless input devices such as Mice and keyboards with Bluetooth connectivity will be more critical.
Furthermore, there is no denying that Bluetooth technology is better placed than its other wireless counterparts are when it comes to using a single gadget to control other electronic devices. Such applications include, for instance, using a Bluetooth-enabled phone to control other home devices such as the entertainment systems, thermostat, security system and so forth.
Moreover, the Bluetooth technology is highly adaptive to new innovations, thanks to the improvements made on the technology by the Bluetooth Special Interest Group on a regular basis. Consequently, Bluetooth will soon offer quality previously attributed to cable connections when it comes to data transfer. For instance, although the first version of Bluetooth, Version 1.2, had a measly 1 Mb/S data rate, the more recent Version, 4.0, has a 24 Mb/S data rate.
Fast growth in wireless technology is clearly evident, and Bluetooth technology is clearly part of this technological tide. Consequently, Bluetooth is very likely going to be used more commonly in future. Also, advancements in this technology will enhance its capabilities in comparison to cable connections and other wireless transmission technologies.
