What is Bluetooth? Before answering this question we need to understand what Bluetooth is all about. Bluetooth is actually a short name for Wireless Application Protocol, and it is a fairly new wireless technology which enable many different electronic devices to communicate with each other. Originally, it was developed as a cost-effective alternative to standard wired headphones, keyboards, microphones, and other wireless peripheral devices. Nearly any electronic device you come across may make use of Bluetooth technology.
Basically, your computer or cell phone can act as a Bluetooth device and communicate with other Bluetooth devices. The process is fairly simple: the computer exchanges information with a paired Bluetooth device, such as your cell phone or lap top computer. In turn, the paired device sends and receives data back to the computer. This allows you to browse the Internet, take pictures, play audio files, or basically do almost anything else that you would be able to do with a wired or wireless mouse. You can also stay in touch with your loved ones or download music to your mp3 player from the web
These days, people are asking more questions as to what is Bluetooth, and how does it work. As mentioned earlier, it was developed by the semiconductor companies to create a standard connection between electronic gadgets. The original use for this wireless technology was for the creation of cheap wireless computers. The popularity of these wireless devices eventually led to the development of specialized Bluetooth modules for use in hand held devices such as laptops and smart phones. Soon after, Bluetooth headsets came about, which enabled people to carry their phone calls over the Internet.
The Bluetooth wireless technology was further developed for use with mobile phones, which meant that people could take their phones with them virtually everywhere they went. Soon after, Bluetooth devices came about, enabling people to surf the Internet wirelessly. Nowadays, mobile phones, PDAs, laptops, and all other mobile devices can be controlled wirelessly over the same network that Bluetooth devices are on.
Bluetooth is classified according to the frequency of its radio signals. Its frequency depends on the manufacturer, but most manufacturers use the 3G frequency. There are also Bluetooth devices that work on a different frequency, which is why the older versions of the technology require you to upgrade your current devices to work with the newer version. Bluetooth devices use the same type of transceivers that other wireless devices use, except they are designed to function with another wireless technology. This is usually done through a converter, which transfers the data rate from your computer to your mobile phone or device.
The difference between a Bluetooth device and a wireless device is that a Bluetooth is designed to have much faster data transfer speeds, compared to the latter. This is why a Bluetooth headset can connect to a Bluetooth device, but it cannot transfer the same data rate when it comes to a PDA. The Bluetooth frequencies that the devices use for transmission are also different in some ways. One of these ways is how the frequency is categorized into seven groups, which correspond to the distance, range, security, convenience, and power.
Due to the great advancements in wireless technology over the past few years, several manufacturers have started using Bluetooth in the manufacture of their mobile phones and other wireless communication devices. These wireless devices are known as Bluetooth enabled mobile phones. These phones are equipped with Bluetooth adapters, which allows the mobile phone to detect nearby Bluetooth devices and connect with them. Once the mobile phone senses a Bluetooth device, it searches for a compatible driver, downloads the necessary software, and then starts the connection process. The whole process is quite fast compared to wireless communication in the past, which required several seconds for the transmission of information.
With Bluetooth technology is becoming more widely used by mobile devices, it is anticipated that a greater degree of connectivity will be achieved in the future. Although Bluetooth is quite new, its usage is quite widespread and most people already have at least some knowledge about it. This means that the market for Bluetooth accessories is not yet exhausted. It is very important that consumers are aware of the specifications of Bluetooth, as well as how they can make the most of their mobile devices when they have Bluetooth adapters. Consumers who are interested in purchasing Bluetooth headphones or earphones will be able to find them in most mobile stores and online stores.
