In the history of mobile phones we come across 4 different eccentrics viz 0G, 0.5G, 1G, 2G, 2.5G, 3G and the latest being 4G which is also sometimes referred as super 3G.

OG: This generation experienced the development of two way radio telephones. Which was successfully tested by soviet engineers G.Shapiro and I.Zaharchenko in 1964, and mounted it inside a car, train and airplanes? This was the device which could connect to local telephone network within a range of 20kms.

0.5G: This was a little upgraded from 0G by introducing ARP, the first public commercial mobile phone network which overcame the limited coverage area drawback.

1G: This generation introduced the wireless technology, mobile technology. It used analog type of radio signals for the transmission of voice. The voice signal transmitted was modulated to higher frequency of 150MHz and above.

2G, 2.5G, and 2.75G: In 19th century second generation was introduced. Which bought GSM, IS-136 and IS-95? Out of which IS-136 use TDMA (time division multiple access) and IS-95 uses CDMA (code division multiple access. 2G introduced wireless transmission via digital signals using circuit switched technique. It bought new variant in telecommunication by introducing SMS (short message service) and multimedia access on the mobile phones.

3G: 2G is widely used worldwide now. But due its limited data rates it’s difficult to use applications like video conferencing, video and music download. Thus, to overcome these drawbacks 3G came into existence which has wider bandwidth and high data rate of about 2Mbps by using packet switching mode of transmission.
The first commercial launch of 3G was on October 1,2001, by NTT DoCoMo. They used WCDMA technology which is better than CDMA. This generation encourages video telephony using EDGE which is the latest GSM technology which supports high rate multimedia. We also have an advanced 3G mobile telephony protocol HSDPA (high speed downlink packet access) which allows data transfer at high speeds.

4G: This is the future generation of telecom industry. Which is fastest and more efficient than 3G? 4G will provide data rate of 100 Mbps for high mobility and 1Gbps for low mobility.

And you never know there is a high possibility of 4G coming to India before 3G.

With the time proceeding ahead there are diverse alterations in technology. Take the web for instance; it has dwelled from Web 1.0 to Web 2.0 i.e. from just an informative web to a more interactive one. Tim Berners-Lee, has come up with Web 3.0 which is also known as ‘semantic web’.

Tim Berners-Lee expressed his views on Web 3.0, as his dream to merge all the links, data and the interactions between the web and users through an intelligent search which even the computer can read and relate to. After this you might have got the rough idea about Web 3.0. In layman terms, you can say it is an intelligent interface between the computers and the web.

As in Web 2.0 ,we can socially interact with the web, which can be addressed as a duplex communication where there is two ways interactivity to read and write, but this interaction is understood only by humans . This is not going to be the case with Web 3.0. The machines are going to be endued with intelligence so that it can read the Web as much as we humans can and give us a more precise and accurate search results. These search results will be a combination of artificial intelligence and semantic web which all together will form a database which gives the admittance to both the machines and the web to incur the information postulated.

Web 3.0 will embark much more than just social networking, collaboration of various websites, use and create applications. It will commence the era of intelligent search with versatile web applications . This will wreak a new platform for open sourced data and software sources via the application programming interfaces (API’s). But, this will increase the security risk. Thus, for Web 3.0 to come into existence is going to take a longer duration of time may be more than it took to bring the Web into existence.

Thus, to take a step ahead in the field of visual search Google introduced its new product named as Google goggles. The name may sound humorous but its function is highly impressive. You just have to click a picture from the android phone, having the Google goggles application, and just Google goggles. It will give all the information related to that picture. For example, at the launch of Google goggles a picture of a bottle of wine was clicked by an android phone. When this picture was ran through Google goggles it showed that the bottle contains some apricots. You can use goggles to find various things like CD covers, bar codes, logos and labels. To read the text Google goggles uses optical character recognition for reading logos and labels.

Google goggles is an android application, which recognises the picture clicked and gives the search related to it as to what is there in that picture. Right now it recognises various pictures of different landmarks, books, places, contact info, labels and logos. It is working on recognising various other aspects like plants, fruits etc.
In layman language, internet means Google. To find any info you just have to know how and what to Google right. And if you don’t know what it is just click a picture and goggles will tell you all about it. This is the latest advancement in the arena of visual search. This application can be very useful in revealing out all the undercover secrets of the corruption happening and can be send on and can be known to each and everyone. This new creation will give advanced knowledge about different things from the educational aspects of the growing children. For that instance any individual, will be curious to know about the thing if he sees something new and knows absolutely nothing about it. This application on the broader scale can help us differentiate between the texture and looks of lookalike things which have totally different characteristics.

With the help of different technologies available today like image processing we can clearly notice even the minute details in the picture. Thus, with this we can conclude that Google goggles is a boon in the field of visual communication.

Coming to the latest advances of internet is the “Internet TV”. This is an entirely new television with a new idea rather than new infrastructure. The IPTV as it is referred to in general; it is more of a revolutionary change from what is existing today. It provides true personalization and two way interactivity. It empowers the user the freedom of choice and access to on demand content, just a click away. It variegate from the regular set of television box by different alternatives to choose from. It is more facile to build an IPTV connection than those which we have now in existence using cables, antennas, satellite discs etc.

The Internet TV can have the edge over the other conventional TV due to its interactivity and easy access. Anyone can reconcile their ideas and can innovate anything and just publish, that’s about it the world can now access that innovation anytime they want. It is an open platform, it has enormous implications if you think it through .To the layman, this service is just like a website which displays screens with pages designed in different mark up languages like HTML/JAVA etc which is stored on a web server that a web browser in a setup box requests and displays. Where it differs from is the richness of multimedia displayed and in CRM (customer resource management).This openness and interoperability makes the service transferable and can work on any platform. Like for instance you build up goodguy.com, that once published can be accessed by all the IPTV platforms simultaneously.

The data and content generated by the users is exponential in its popularity and is applicative in everyday life. And IPTV technology beautifies it by giving the full freedom to explore new things which no other TV can do. But where comes the comfort comes the afflict. To maintain the IPTV services you need broadcast rights which differ from country to country. To maintain the HD (high definition) quality of the multimedia high cost is needed and also the quality of the audio video varies with the internet speed the minimum speed required is 1500 kbps as HD is highly sensitive to bandwidth, high bandwidth is to be maintained. So the bet is to invest in LLU (local loop unbundling) via NTL which allows multiple telecommunication connections, rather than using IP(internet protocol) as their transmission media through coax cables. There are many technical hurdles but when we can use it for watching video on you tube, providing IPTV services wouldn’t be a tough job.

The IPTV is existing in the market but the usage is minimal. As also we can say that the infrastructure has not much potential in technology to use IPTV on a wider scale. But as it is said with time everything changes and so good and developing changes are expected in this field.
