It is hard to imagine such a world, in this world, Smartphone speed faster speeds than we are now.
Now, you have been able to pick up the phone and ask Google a question, and get an answer in seconds.
Next-generation wireless technology is going to be faster, but its main goal is not to speed.
Next-generation wireless network will handle we are currently experiencing one of the most troubling problems: a stable and fast network connections.
5G network's main goal is to give the end user always in the connected state, whether they are indoors or outdoors, or whether they are closer to the window was hiding in the basement.
We need such a strong networking capabilities, partly supported devices 5G the future goes far beyond a Smartphone--it also needs to support smart watches, health wristband, smart home appliances such as nest-type Room thermostats, etc.
What is a 5G?
5G networks is a next-generation wireless network. In the past few years, ever since the 4G network promotion, we have seen new development trends, including LTE, LTE Advanced and Verizon XLTE.
All these developments are based on the same core requirements, owned by the 4G network. However, the real upgrade of 5G network 4G network, and basic requirements and different from today's wireless networks.
We need to understand the differences in these networks, because your cell phone performance will depend to a large extent you access network. It is not only your cell phone is a small symbol of the upper right corner.
The leap from 3G to 4G, give high speed download qualitative upgrade. On the 3G network, and almost impossible for us to use a service like Netflix. This is one reason 4G spread in the past few years.
So, what 5G network will bring about? What are we going to do with it? At this stage, it is difficult to answer this question. However, industry analysts have begun to predict.
Speed is not the most important thing
Pervasive this misconception: 5G means Super fast data transfer speeds. So far, it is because we see tests stress 5G much faster than today's Internet.
Last May, Samsung claims that its upcoming 5G of data can be transmitted per second over 1G.
Relatively speaking, now relatively fast LTE network 60M data can be transmitted per second, which is equivalent to about 0.05G.
Wireless network faster than you can with any smart phone experience speeds are much faster. Google announces it, even at the rate of 1G per second, you can also use less than two minutes to download a full HD movie.
Alcatel-Lucent Bell Labs Vice President of wireless research project Todd Seiser (Tod Sizer) said that the next-generation wireless network will certainly be higher than our current network speed, but this is not 5G important to consider things.
"If you say that speed is something we need to be improved in the 5G network, you would be wrong. "Seiser said in an interview," the end user does not care about speed. What they care about is that they use application needs. ”
The 5G network, we will see the biggest improvements is its flexibility to support a variety of different devices. In addition to supporting mobile phones and tablet computers, the 5G network will also need to support a wearable device, such as fitness tracking and smart watches, smart home appliances such as nest-type Room thermostats, etc.
"In a given region supports numerous devices, this is our design goals. "Seiser said," we are confident that in the future, everyone will need to have 10-100 devices for their services. ”
This is why it is difficult to determine which technologies 5G network need one reason. It's hard to know what support all these devices require a lot of data capacity.
"Not only is it support for more data, but also to support increased usage. "The consumer market research firm Current Analysis, and infrastructure Vice President Peter Jia Ruiqi (Peter Jarich) said," it became a real challenge. In this regard, we still don't know the answer. ”
Seiser said, speaking of 5G network, improve end-to-end performance is another major issue. End-to-end performance refers to your smart phone's wireless network and server maintain a connection between your search information.
When you send text messages or surf the Web, poor end-to-end performance is not attracted special attention. But you watch Netflix movies via Skype video calls or when you will be clearly felt. When watching the video, if you found that video playback is not smooth and even stagnant, it may well be for the sake of poor end-to-end network connectivity.
Seiser says next-generation wireless network will also bring the substantial expansion of Smartphone and mobile device battery life. Because there are so many smaller tasks requires the application to run without a break.
For example, an e-mail application sends a request message to the server over and over again, to see whether there are new e-mail arrives.
Although these requests are short, and over time, but they will continue to eat into your cell phone's battery life. Seiser at Bell Labs team one task is to find a better solution for dealing with these requests for information.
"There are a lot of applications will continue to send these short messages. "Seiser said," if I am able to deal with this information, then I will be able to greatly enhance the Tablet PC's battery life. ”
10 years, don't expect to see 5G network
It is difficult to understand what the 5G network will provide, in part because it hasn't even set. International Telecommunication Union has yet to explain 5G what you need to include technology and special requirements.
Jia Ruiqi explained that confirm the appropriate specifications, the building infrastructure is a slow, gradual process.
This task includes identifying 5G network technology requirements and to meet these requirements, such as standard reaches a certain speed, determines which components need to be added in the smart-phone and antenna to meet those standards.
In normal circumstances, to let the next generation networks require 10 years ' time. Seiser and Jia Ruiqi, said 5G the initial paving work of the network may have to start in 2020 we could take until 2025 to to see it widely used.
"To the laying of a wireless network, you need to invest a lot of money and effort. "Seiser," says wireless network investment could reach billions of dollars, or euros, it takes a long time to recoup their investment. ”
Earlier this year, media reports said, Korea will invest $ 1.49 billion to build 5G networks. At the end of 2013, the European Commission will launch a cooperation program, investing $ 963 million for 5G r.
To be fully laid to new wireless networks, often require billions of dollars in funding, creating 5G is no exception. In 2012, the AT&T had invested 14 billion dollars to expand its LTE network, scheduled for the end of 2014 to cover 300 million people. This is just a wireless operator in the LTE network within three years to put the construction funds. Think about it, in 10 years, each wireless carriers need to spend how much money to create their own 5G?
Seiser and Jia Ruiqi believe, 5G network's ultimate goal is to make you think of nowhere without an Internet connection, wherever you are in the underground or in remote areas. But that does not mean fixed broadband will become outdated. Without the aid of fixed-line broadband connections, we can never have enough bandwidth to handle Internet traffic.
However, the 5G network will strive to achieve this goal.
"People who were born in 2000, the world they can't understand us: we need brothers and sisters share a handset, we cannot easily access any information we want using a mobile phone. "Seiser says," the crowd never knew the Internet connection is not on the case. For these people we want to design a next-generation wireless network. ”
