How 3G will be of use to common man

You can understand 3g or be confused by it but the fact remains that you just cannot ignore it. The layman's world has grown too fast. Every day technical jargon keeps getting dumped into our routine lives and we are not sure if we really have gotten the hang of it all. Yet, the progress is palpable. It is there all around us and we embrace it and move on, sometimes with almost zero comprehension. we have been hearing the words 2G, 3G and even 4G, now that we all know about iPhones. So what are these Gs? What do they stand for and what exactly do they do? How does it reach the layman and of what use is it? Well, dear reader, that is exactly what this post will try to lend clarity on.
So for the most elementary question, What do the Gs stand for? Well, G means Generation. The world of telecom administrators have named the connections available as First, Second and Third Generations. An obvious illation here would be that each progressing generation is better equipped to connect the world than the previous one. Now when the mobile phones first came into existence 1G networks were used to transmit these signals. The signals used in 1G were analog. Meaning they were prone to many distortions, interference, cross calls im-practical in a few areas and lots of losses. This also meant the handsets had to bigger in size to facilitate proper usage. Then came 2G, where in the major difference/*improvement from 1G was, these signals were digital. The transmitted messages were coded digitally and this eventually improved all the disadvantages of the 1G connection.

Presently we are in the midst of a revolution(Late in India). The 3G standards have come into the nation and along it brings a fresh crisp and faster life. 3G technology enables faster internet access speed, owing to the fact that the channel available for internet access is larger than the one available in 2G. In 3G one can expect speed close to around 200 Kbit/s and more. Refer the Wiki page : http://en.wikipedia.org/wiki/3G. Now the 2G networks suffered due to lack of bandwidth and so it couldn't offer many services. But now that the 3G is here it offers,, by virtue of its bandwidth availability a host of mouth watering features like :
  • Mobile TV – a provider redirects a TV channel directly to the subscriber's phone where it can be watched.
  • Video on demand – a provider sends a movie to the subscriber's phone.
  • Video conferencing – subscribers can see as well as talk to each other.
  • Tele-medicine – a medical provider monitors or provides advice to the potentially isolated subscriber.
  • Location-based services – a provider sends localized weather or traffic conditions to the phone, or the phone allows the subscriber to find nearby businesses or friends.
  • So keeping away all technical terms and speaking strictly as a normal common man, 3G stands for the following :
    1. Faster speed for internet 2. More features like TV and media streaming 3. Video calling facility (needs more bandwidth hence not available in 2G ) 4. More security over 2G 5. Truly, the power of the world will come into the palm of our hands... So long then dear readers, hope this post did, if not completely at least partly, shed some clarity on the happening 3G phenomenon. Cheers source
