The Unbelievable Yet True Reach of Bluetooth Technology

February 5th, 2010



Today with world becoming flatter and flatter the first aspect that people look for in any gadget is the bluetooth connectivity. Well it all started way back in the 10th century when Harold Bluetooth wanted a code name for the Trade Association and after the much discussion finally the name “Bluetooth” was assigned looking at the future of wireless technology. While the Bluetooth specification was developed in 1994 by Jaap Haartsen and Sven Mattisson, who were working for Ericsson Mobile Platforms in Lund, Sweden. Since then the technology has evolved tremendously.

Bluetooth is a wireless protocol utilizing short-range communications technology making room for data transmission such as videos, photos or any data from fixed mobile devices creating personal area networks (PAN’s). In simple words bluetooth technology helps in connecting multiple devices and providing best possible synchronisation. You can transfer and exchange any piece of information or data between devices such as mobile phones, laptops, printers, GPS receivers and many others just to mention with bluetooth technology.

Initially bluetooth 1.0 and 1.0B versions came into picture which had many problems that gave space for bluetooth 1.1 IEE Standard 802.15 helping mobile phones to connect efficiently. Then came bluetooth 1.2 v which had several enhancements to the 1.1v. Finally the most advanced ones which are used today are bluetooth 2.0v and bluetooth 2.1v. The connectivity range can be 10 metres or 100 metres depending on the class of the bluetooth device in concern.

The unbelievable reach of bluetooth technology is really commendable. It started with mobile phones making them capable of transferring videos, music and other digital content to other devices. And now we observe that bluetooth watches which can perform all bluetooth function such as receiving and rejecting calls with buttons on the watch. What’s more the trend has reached to the making of a bluetooth-enabled umbrella that lets you freely take and make phone calls when it’s raining ensuring you that your handset doesn’t get wet. It also includes entertainment applications such as radio, small keyboard.

IPTV Technology Simplified

January 15th, 2010



IPTV technology is the latest in innovations for getting the daily communications that people thrive on and enjoy. You may have heard of the ever-popular Voice over Internet Protocol (VoIP) phone service from companies like Vonage. Well, to make this easy to understand, IPTV is the same, only with television over internet protocol, instead of voice. Ultimately, TV can be watched anywhere through a broadband connection with IPTV, which makes it a very popular choice for those looking for the latest and greatest in new technology. Telecommunications companies are looking for new revenue, and they have found it with this process.

IPTV technology is based around a similar system to that of cable. There is the need for a computer or a set-top box of sorts so that the images can be transmitted, decoded, and then sent out to the television in a format that can show them properly on the screen. This type of broadcasting can be done by a simple broadcast or multicast if someone is trying to get a channel out to everyone. However, it can also be done on an ‘on demand’ basis, where people are able to stream material to just one or two subscribers who have requested the show or material in question.

Maintaining The Technology

There is a lot of work and technology that goes into maintaining IPTV technology. Streaming over broadband needs to be done efficiently and in a format that will allow for the seamless transition of the data that is being sent. The process for using IPTV involves lots of splitting, encoding and distributing efficiently. The provider end is very complicated, but for customers it is a simple tool to use. Channel selection for IPTV is executed via a membership format known as IPGMP, or IP Group Membership Protocol. Due to the data transmission, this makes sending multiple channel signals and changing channels much simpler than it might be otherwise.

The New Kid On The Block

IPTV technology is still relatively new, but it is a popular item for those who are looking for the latest technology. Of course the quality of service is vitally important to the customers, and is something that must be maintained correctly in order to make the service a viable means of viewing television. As the popularity of IPTV increases and so does the number of users, the improvements and quality of the services provided will follow suit. In time, providers will have a lucrative new way to attract business when other products are growing stale.

Optical Fiber Systems in Long Range Radio Communication

November 17th, 2009



Optical fiber systems are great importance in the long-range radio communication scenario. The optical fiber technology has greatly improved in the recent times. It is in fact one among the most recent technologies that is being use in the communication front. The superiority of the technology has been instrumental in the innovations in the filed of communication. The usage of the technology in telecommunication systems, data systems and cable television transmission has greatly contributed to the efficiency factor of these areas.

The scientific application and engineering of optical strands is the basic idea behind the systems. The data is transmitted in the form of light rays in the optical fiber equipments. Considering the speed of light, the speed of data transmission can be estimated. The high speed of data transmission has greatly contributed in quick and effective communication in various fields. The technology known as ‘total internal reflection’ is being used in this technology. The light signals are contained inside the core of the thread and this makes the system more efficient than the other systems. The data signals tend to diminish in other systems. This is the reason why it is used n long distance data transmission. The higher spend compared to the conventional techniques is also among the reasons for its usage in the long distance data transmission.

Structure of Optical Cables

Many different types of optical cables are used in the communication scenario now. A basic optical; cable has two layers. The center part of the strand is known as the core. The signals in the form of light rays travel through the core of the strand. The protective shield outside the core is known as cladding.

The cladding has to major functions. The main function is protecting the core from extreme interferences. Cladding also serves as the internal reflective boundary that enables total internal reflection. It is also the key factor as it enables the signals to travel towards the right direction towards destination.

Advantages of the System

Compared to the traditional data transmission techniques, the optical fiber technology offers many advantages. The considerable reduction in the signal loss is one among the most important advantage offered by the technology. Optical threads are also immune to the electromagnetic interference that is common with the traditional metal wire transmissions. There is also a considerable increase in the data transferred through the system. The great technology used in the components also ensures the quality of communication.

The technology also makes use of lower weight equipments and components reducing the transportation cost and handling cost. Enhanced security and higher performance are the two major aspects of this system. Lack of radiation is also among the factors that make the technology popular.

Optical strands will not produce sparks making it a safer technology when compared to the conventional techniques. Protective qualities of the cladding contribute greatly to the safety aspect. Cost effectiveness of the system also makes it a safe choice to make.

However, long distance radio communication has been greatly benefited with the introduction of this technology.
