Simplified Wireless Communication with Bluetooth

Monday, December 24th, 2012

Bluetooth is a robust wireless data transmission technology that has removed a lot of complications from the data transmission process between different electronic devices. Although the distance of transmission is small as compared to other wireless technologies like Wi-Fi and WiMAX, the Bluetooth compatibility has the most notable advantage of doing away with all the wires, cords and adapters allowing the Bluetooth compatible devices to communicate with each other wirelessly.

The Evolution of Bluetooth

Bluetooth with Laptop
Since it was first introduced in 1994 by the telecom vendors Ericsson, the Bluetooth technology has undergone many improvements to compatibility and data transfer rates with each new version of the Bluetooth standard. Following is a brief history of the Bluetooth’s evolution as a mainstream form of data transmission standard.

  • Bluetooth 1.0 – 1.2 – The very first version included a number of bugs and compatibility issues which were later addressed by the updates Bluetooth 1.1 and 1.2 which also improved the transfer rates.
  • Bluetooth 2.0 – Along with minor bug fixes, Bluetooth 2.0 introduced Enhanced Data Rate which improved the data transmission rates; and featured backward compatibility with Bluetooth 1.2, enabling the older devices to connect to the newer ones without any issues. It was followed by Bluetooth 2.1 which improved the devices pairing speeds and improved the data transmission security. It also provided Extended Inquiry Response which enabled the additional hardware during the connection process.
  • Bluetooth 3.0 – The new devices listed as Bluetooth 3.0+HS come with an enhanced High Speed feature that allow data transmission rates up to 25 megabytes per second using the wireless 802.11 networking signals. Users are allowed to switch between the Bluetooth and 802.11 transfer mode for power control.
  • Bluetooth 4.0 – The latest version of Bluetooth standards include both the traditional Bluetooth protocol and the High Speed (HS) protocol as its core for a very high level of compatibility with older devices. It also introduces a low energy protocol that saves power and ensures lower power consumption compared to its predecessors

Bluetooth 4.0 compatible devices and accessories will be called Bluetooth Smart ready to distinguish themselves from other Bluetooth enabled devices. Latest smartphones including iPhone 5 and Samsung Galaxy S III are Bluetooth Smart ready which means that these phones will be able to connect to other Smart-Ready devices as well as perform classic Bluetooth functions such as connecting to old devices and transferring files and so on.

Bluetooth Compatible Devices
Bluetooth Headset
Today we see the use of Bluetooth technology in almost all of the electronic devices. These include, for example:

  • Wireless stereo headphones and headsets with the mobile phones and music payers so you can communicate easily
  • Wireless mouse and keyboards with laptop computers to enable cordless data transmission
  • Remotes and other accessories with TV, air conditioners and other electronic devices
  • PC cards, radios and dongles etc.
  • A shared printer and fax machines so that different computers can connect to it without any complicated tangle of cables

The Many Advantages of Bluetooth

The revolutionary Bluetooth technology has had impact in almost all the industries including commercial and personal use. This is due to the many advantages of Bluetooth compared to other data transmission methods. These include:

  • Bluetooth is cheaper
  • Bluetooth is easily available in almost all electronic devices therefore compatibility issues don’t have to be dealt with
  • Bluetooth is less complicated and doesn’t require complex cables to be attached to devices.
  • Less power consumption
  • Healthy scope for improvement and further developments
  • Many Bluetooth enabled devices can connect with a single Bluetooth transceiver simultaneously, thus doing away with the requirement of having separate transceivers for each device

Blue Computer Concept
Therefore, a wide range of electronic devices including desktop computers, laptops, PDAs, smart phones, tablets, printers, screens and virtually any device with Bluetooth compatibility can connect to Bluetooth system. Data transmission, although slower than the traditional USB cable attachment, is faster than the mobile phones’ GSM, GPRS and even the 3G high-speed transmission technologies.

In today’s world, technology has become a key factor for many companies to provide their customers with the efficient, responsive and sustainable form of public service. The changes brought about to the technology world by the Bluetooth technology is commendable and inspires embracing the new technology. The implementation of Bluetooth technology into public service and government departments has the potential to benefit the masses.
