Samsung demonstrated 4G technology

The Korean giant has made impressive performances for future mobile technology when transmitting wireless signals "rocket" speed to a bus running.

Network connection is fast and powerful enough to support live images - including high-definition movies (HD-DVD) - transmitted by Samsung from the conference room.

And to demonstrate this "mobile" technology in the right sense, the device inside the bus has transformed "smoothly" and smoothly between two broadcast stations. This means that the signal will not be dropped in case the user is moving at a fast speed.

However, this promising prospect is still far away. Currently, Samsung's signal receiver is as big as the . refrigerator. According to Lee Ki-tae, director of Samsung's telecommunications department, after 2008, the new company can shrink this device size enough to integrate into mobile phones.

But even then, the frequency of waves needs to be repositioned and applied to the standard frame. Thus, the earliest, 4G network will not be able to reach consumers before 2010.

Great prospects, but still . far away

Moreover, the mobile network is still not calm after the fever (inflated) named 3G. They have spent billions of dollars to buy technology licenses and are deploying it on a worldwide scale, but so far, profits have yet to see.

However, mobile networks have come to understand one thing: Users need a really compelling, compelling reason to be able to welcome 3G and 4G crickets.

" Technology must bring real value to users, otherwise they will not pay for it ," said Alberto Ciarniello, vice president of Telecom Italia.

Therefore, the key task of mobile networks now is to hunt for a "top application" - a feature that users cannot "live without" to attract users to new technology. According to analysts, high-speed wireless access cannot be "strong enough" to convince customers to open their wallets.

At the same time, another wireless technology called WiMax is also emerging. It may not be as fast as 4G, but the speed of WiMax has also far surpassed the average broadband connections today.

South Korea has become the first country in the world to offer WiMax services and plans to cover the technology throughout Seoul in early 2007. Meanwhile, US-based Sprint Nextel mobile network is also planning to declare WiMax website in some areas at the end of 2007.

" We are at an early stage of an explosion, " Sprint spokesman said.
