4G Mobile in Shanghai, Fast bandwidth test to see high-definition TV

In Electronic Infomation Category: R | on November   1, 2010

The Yangtze River Delta by the newspaper Xinhua news gathering Joint Center, East Radio, LONDON launch large-scale cross-media interviews - "the peoples livelihood Interview Shanghai 2008" into the fourth. Shanghai Science and ADS931E datasheet and Technology Committee, Renshou Zi Qi before our guest. 4G mobile phones, electronic tags, super capacitor car ... ... appear in the interview these high-tech terms, is a lot to open the eyes. In fact, these research results, or have appeared in our cities, or are in full swing in the development process, is expected in the near future to enter public life.

Communications technology 4G mobile bandwidth of 100 megabytes is expected to come out

Reporter: I think the former is small, we feel if someone took a "Big Brother" is especially beautiful, but now the phone has been popular, recently listed the 3G cell phone.

Qi Shou Son: the former "Big Brother" turned around like a big, have to take that time with a mobile phone package. Later developed into the second generation of mobile phones, we call it 2G phone. The phones use digital signals, but because of its limited bandwidth, and ADS931E price and now mainly audio, that is, you can hear the sound, video is more difficult. 3G mobile phones are now developed to

, 3G bandwidth wider point, the audio and ADS931E suppliers and video have, but the bandwidth of the current deficiencies in the process of browsing the video is not smooth. The development of next generation mobile phones are also actively studying a 4G mobile phone, which is the fourth generation of mobile communication, which is now one of the countrys major projects, it is possible to achieve bandwidth of 100 megabytes. Of course, the mobile phone after all, is a commodity, research and development process must take into account its price.

From 2G, 3G to 4G, which is an identity change, but also the bandwidth changes. It uses a broadband network is not moving, but the fixed broadband network, and now through the research, we have a new generation of broadband technology has been overcome. It can provide broadband network is now wider than the bandwidth, the original is 2 trillion, 40 trillion now is about 20 times to raise the. This cycle of songs on a lot of viewing the program, and several thousand sets of anything, including on-demand. There we are talking about high-definition television, and remote medical care and education, with the facility to see is very clear, very strong realism.

Present, 4G Mobile is testing the process, interested, can go and see, that does not feel like the picture very clear.

But because the high-tech must have a very good price, we are now ongoing effort to reduce its costs. Of course, after expanding the number of users, the cost will come down.
