Some Information On Bluetooth Technology
Ever since the origin of mankind, human continued to develop and evolve according to need and adapted many technology in order to evolve more efficiently. In the backdrop of this ever evolving nature of human we invented many ways of communication starting from sign, symbol, language, and then acquired many modes of communication for communicating ranging from short distance to long distance, invented telephone, in this contrast of development we developed wireless communication and also a unique technology popularly known as BLUETOOTH TECHNOLOGY. This article will give an insight and depth knowledge about this Bluetooth Technology. There are many questions like what is this technology?, how it works?, what are advantages of this?, what are disadvantages of this technology?, any many more such questions are going to be answered in the following lines, to begin with I will like to start from:
Origin and History of Bluetooth
In 1998, Ericson Technology Licensing, Intel, Nokia, IBM and Toshiba came together to form the BLUETOOTH SPECIAL INTEREST GROUP (SIG). The SIG backed the research and development of Bluetooth emerging technology advances monetarily. In 1998 after formation of SIG they officially trademarked the name Bluetooth, which is borrowed from a former Danish king. King Harald Bluetooth, who was famous for uniting countries in distress had brought Scandinavian Europe together after period of Civil war. The SIG thought it was appropriate to name the technology after the king because it is a single device with the capability to bring different technologies together as well.
WHAT IS BLUETOOTH TECHNOLOGY?
Bluetooth is a wireless technology which can simply define as a wireless connection within short distances which helps to connect electronic devices for the purpose of transfer and sharing of data as well as voice signals. It is short range communications technology that is simple and secure, which uses short wave length radio transmissions in the ISM band from 2400-2480 MHz and aimed to replace the cables connecting devices while maintaining high levels of security. This technology can be find in billions of devices and home entertainment products.
HOW IT WORKS?
Here without going into the technical depth explanation will be in simple words so that a layman can understand the working. Bluetooth technology uses a radio frequency that is available around the world. Since its inception in 1998, SIG modified its technology to make it faster and better with a new multiple-connectivity feature meaning that Personal Area Networks (PAN) and Piconet will be possible. Piconet is the ability of two or more Bluetooth devices with the same profile synchronizing automatically when they come within range.
When two Bluetooth enabled devices connect to each other, this is called Pairing. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity meaning that you can easily connect whenever and wherever it's convenient for users. Each device in a piconet can also simultaneously communicate with upto seven other devices within that single piconet and each device can belong to several piconets simultaneously meaning that the ways in which we can connect our Bluetooth device is almost limitless.
WHAT ARE ADVANTAGES OF BLUETOOTH?
This technology is very inexpensive almost all wireless, and some non-wireless devices are already equipped with Bluetooth technology. This is simple to use as there is no need to configure any settings as the automatic synchronizing does it for you. It also uses a standardized wireless protocol, meaning that two devices within range, without considering make or model, can talk and communicate with each other without changing settings.
Besides being inexpensive some of its advantages are its robustness, low power, its universality meaning its widely used, its free of charge, controlled by self and above all its ability to simultaneously handle data and voice transmissions, which provides users with a variety of innovative solutions.
APPLICATIONS OF BLUETOOTH TECHNOLOGY
One of the first application of this technology is wireless control of and communication between a mobile and handsfree handset. There are various applications of Bluetooth technology which we see in our daily life apart from them some major applications are as follows:
- Wireless networking between PCs in a confined space and where little bandwidth is required.
- Transfer of files, contact details, calendar, appointment and reminders between devices with OBEX.
- Replacement of previous wired RS-232 serial communications in test equipment, GPS receivers, medical equipment, bar code scanners and traffic control devices.
- Wireless bridge between two industrial Ethernet networks.
- Real time locations system are used to track and identify the location of objects in real time using "Nodes" or "Tags" attached to, or embedded in the objects tracked, and readers that receive and process the wireless signals from these tags to determine their locations.
DISADVANTAGES OF BLUETOOTH TECHNOLOGY:
As every technology have its pros and cons so does Bluetooth technology. Inspite of its wide range of application and all of its advantages there are some disadvantages of this technology as well.
- Sometimes the fact that causes problem with the functioning of Bluetooth is that it uses same frequency as WaveLAN standard.
- Due to its Omni-directional functioning, it encounters problems in discovering the intended recipient device amongst many mobile devices in a room. But this problem can be overcome by some security mechanism.
- Now when it comes to transferring large data using Bluetooth it may take centuries to complete transfer as the maximum transfer rate is 1 Mbps. where infrared has maximum speed of 4 Mbps and Wi-Fi is capable of even higher rate.
- One may find problem of range while using Bluetooth because its range radius is 30 foot and if we want to access some device outside this radius it will be a problem.
- From the security point of view data transfer over Bluetooth is not secure as this technology uses radio waves to communicate it makes easier for a hacker to break into the secure wireless network.
- For using Bluetooth more battery of a connecting device is used and so the device runs out of juice sooner than expected.
- There is also possibility of health risks due to excessive use of Bluetooth technology as long exposure of waves may prove harmful to health.
CONCLUSION:
Inspite of having so much disavantages, its advantages still out-weighs its disadvantages and it can be concluded that Bluetooth is a wireless technology that will make connections between various devices. It takes away the need of several problematic cable attachments for connecting cellular phones, handheld device, and computers. It is easy, simple and inexpensive.
So when we have to think wireless Bluetooth is the best way to communicate.
