The 3G Technology Allows For Video Conferencing
In today’s consumer driven world, it is hard to find a person that does not own a cell phone. Apart from making phone calls and texting cell phones today are used for a variety of different purposes. Most cell phone models today include features like a camera, music players, and even applications that can trade stocks.
One of the best features provided by cell phones is the ability to connect to the internet which has opened up a world of possibilities in mobile phone communications.
When you are having a conversation over the phone, wouldn’t it be amazing to see the person at the same? This is now possible through video conferencing. Video phone calls have been possible since the 1970′s but are surely coming of age now with the introduction of 3G technology.
3G technology refers to the third generation of mobile technology which enables high speed data transfers over fibre optic networks. 3G is definitely a step up from its predecessors 1G and 2G technologies which used analog and digital technology.
When the first video phones were introduced in the market, they could not be used commercially because of their high price and the amount of connections that they required in order to function. This was solved to a certain extent by technology that compressed the audio and video thereby reducing the amount of external connections. However the compression affected the quality of the audio and video.
Webcams also became popular in enabling video conversations. But these are not as portable as a phone and require the user to install software. However the newer models of laptops now include a webcam in their original design.
Digital video transmission is intended to send a larger amount of information that the audio stream. It is a great challenge for the mobile phone that transmits data via radio signals have a limited amount of bandwidth to operate. Thus, although powerful 3G networks is not practical to send bits of information. Instead, the video is compressed to reduce the digital information in a manageable format. Phone receives the sole purpose of breaking ranks and expand.
Through 3G networks, the quality of the video does not suffer as much as it would with any other network. This is because files transferred over 3G networks employ better spectral efficiency and thus get the most out of the available bandwidth. An application like this would generally use up a lot of power. But 3G phones have inbuilt microchips that can compress video in real-time without using up too much of the phone’s battery.
3G technology is relatively new to the Indian Market, but will soon make its mark with the large number of private companies that will soon release their services.
