[mobiler0]

i would hardly believe if i use 3g in my phone using my airtel sim card .
and now trai wants india to match other countries , looking for 4g in india:o:o:confused:

TRAI Chairman J S Sarma "Yes. We are starting the process and would come out with a consultation paper to look into various issues relating to 4G telecom services,"

I think this time they think right

Bcoz implement of 4G instead of 3G is much more valuable.

What is actually the 4G technology? Please explain.....I think India has to First Implement 3G all over the country first..

4G mobile technology is the name given to the next generation of mobile devices such as cell phones. It became available from at least one provider in several parts of the US in 2009. There is not yet an agreed industry standard for what constitutes 4G mobile, so for now it is merely a marketing term.

The use of G, standing for generation, in mobile technology covers the major advances of the past 20-30 years. 1G technology involved the first widely available mobile phones. 2G technology, which began in the early 1990s, switched to a digital format and introduced text messaging. 3G technology improved the efficiency of how data is carried, making it possible to carry enhanced information services such as websites in their original format. The latest iPhone is the best known example of 3G technology.

4G mobile is not yet established as an agreed set of standards, so its features are currently simply goals rather than requirements. As well as drastically increasing data transfer speeds, 4G mobile should use enhanced security measures. Another goal is to reduce blips in transmission when a device moves between areas covered by different networks. 4G mobile networks should also use a network based on the IP address system used for the internet.

Within the United States, there are two major systems using 4G mobile technology. One is known as WiMax and is backed by Clearwire, a firm whose majority owner is Sprint Nextel. It began testing services in Baltimore in 2008 and was set to expand this into major new markets in 2009. Sprint intended to have 80 cities covered by the end of 2010.

The rival system, Long Term Evolution or LTE, is backed mainly by Verizon. It was expected to be ready for testing in 2010 but not available for widespread use until 2012. LTE's backers hoped to overcome this disadvantage by offering faster speeds and producing cheaper equipment.


Unlike previous generations of mobile technology, 4G mobile will be widely used for internet access on computers as well as carrying cell phone communications. Customers in areas which have strong 4G coverage will be able to use it for a home broadband connection which doesn't require any cabling to their household. It can also be used for accessing the internet on the move without having to be in a wireless hotspot such as those offered by some coffee shops, airports and libraries.

UPA seeking for money because they has spent Lot's of money in irrespective projects.

ya already IT minister has made big loss of Rs.60000 crores in spectrum allocation..now again planning for big amount itseems...first let them start 3G....then they can talk abt 4G..

No technology would be complete without a looming upgrade for tomorrow.

The existing 3G W-CDMA standard will be replaced in 4G by VSF-OFCDM and VSF-CDMA. VSF-OFCDM allows extremely high downlink connections, both indoors and outdoors. VSF-CDMA provides high-efficiency, high-speed packet transmissions for the uplink.

The 4G adoption of concatenated FEC (Forward Error Correction) will allow much larger data packets to be transmitted and at the same time reduce the bit error rate. This will increase the overall data through-put.

One of the main advantages that 4G technology will have over 3G is higher data rates. This will benefit the end user by allowing faster access to multimedia and video while on the move.

We don't loose Rs.60000 crores in spectrum allocation because Bandwidth will be same in both technology only Frequency band change 2 - 8GHz instead of 1.8 - 2.5GHz in 3G.

How can they jump a step.

I have CRT TV and I am planning to buy new TV.

I have 2 options go for LCD tv or LED tv.

and definitely I will go for LED because instead of buying 2 TV sets in couple of years. I would like to go for the latest one. This is richer way to go for cheaper.

wait for couple of months....3D tv will be out.....
