"Wireless City": Real estate Built in heaven

"There are still too few wireless access points to meet the need to surf the web anytime, anywhere." I know the free wireless Internet access is only cafes, high-end hotel lobby, and so on, and slow speed, can not meet demand.　　"Beijing University teacher Liu Xilei told reporters that with the popularity of smartphones and tablets, it has become a basic demand for modern citizens to surf the city anytime, anywhere." "People only need to use mobile phones, you can through the system for Social security account inquiries, appointment registration and other operations, but also through mobile phone inquiries real-time traffic and parking surplus." These are just some of the functions of a wireless city.　　"A wireless city concept is approaching," said Peng Guo, a telecoms insider, to reporters. The so-called "wireless city" is the entire city within the scope of the implementation of wireless network coverage and services, providing anytime, anywhere access and faster wireless networks. Computers, smartphones and so on no longer need to connect network cable can realize networking; In addition, Wireless broadband network coverage, not only confined to a room, a building, but as mobile phone signal, covering the entire urban area.　　Users use mobile phone to watch TV, play network games, mobile video chat, use mobile phone to hold or participate in video conferencing, home digital network, wireless transmission documents and photos, such as large files, wireless network hard disk, mobile e-mail and so on. As the Beijing Olympic Games Wireless city government chief advisor, the University of Posts and telecommunications Song Junde Professor has been actively advocating the wireless city construction. For why to build a wireless city, he said: "We like to see video, play games, this is the bandwidth requirements, bandwidth is the real estate in the sky, we must find ways to expand this part of the wireless city is the demand for bandwidth, so we have to build." In addition to learning and playing games, now life with mobile phone and terminal has a relationship, I buy things can use E-commerce, I read can be transferred to my mobile phone reading, go out to the car is a card, applications have become wireless, anytime, anywhere, these requirements in the increase. So from these points of view, we build a wireless city to meet these requirements. Song Junde said that Beijing has been trying to build a wireless city since 2006, when it was mainly to welcome the 2008 Beijing Olympics. Some of the sites near the Olympic venues have done a better job of solving the demand, but because of the limited coverage, no wireless city has been built.　　Song Junde explained that the main reason was that the operation was supported by an emerging operator, with limited talent and financial resources, so that several key areas were not well covered. Beijing civil servant Shining told reporters: "During the Olympic Games, the wireless network is really easy to use, but I understand the ' wireless city ' still has a big gap, the first is the access point is less, the speed is not fast enough, without these, wireless city's other functions are empty talk." "Fujian University student Zhang Zhiman is practicing in a Beijing unit, and he thinks the current network coverage is too limited." Because the leased place does not have the wired network installed, Zhang Zhiman can only use the mobile phone to surf the internet, "in the field realXi, will suddenly receive the teacher's homework requirements. Homework finished, only through the computer into the mobile phone, and then sent to the teacher's email address, and sometimes slow speed. "Liu Xilei also believes that the current city life is more convenient than before, but the wireless coverage is not ideal, if the wireless can cover every corner, and through the mobile phone, computer and other terminals can achieve related payment is better." "The current wireless network, to meet basic communication needs, such as e-mail or through the Network tool chat, but many very specific applications are not, such as some insurance procedures wireless operation is difficult to achieve, I live in the community to buy electricity still have to go to fixed outlets." "The public expressed their desire to realize the" wireless city, Song Junde also said that the current wireless situation does not satisfy the public, "Wireless City" is actually not a simple WiFi mode of wireless city, a new generation of "wireless City" concept is emerging, this is WiFi, 2G, 3G network mixed use, But there is a unified platform running, "WiFi is not successful, because pure WiFi is impossible to cover the entire region of the world." Every layer of our buildings must have its own IP, we calculated that the Beijing government to vote 20 billion to meet the basic needs. Song Junde said that some cities have long started "wireless City" attempts, such as Singapore and Taipei, but at the beginning they were not well evaluated. The reason is that they rely on wifi alone to practice, investment is very large, there is no transition, no good business model. Many cities in China are now building "wireless City", Song Junde's point of view is that it can be successful, "First of all, the development of technology provides the possibility, and the three major operators of China Mobile, Chinese Telecom and Unicom have their own business model, followed by the support of the Government to provide a strong guarantee."
