5G before business, companies still need to overcome many obstacles. For example, the industry has not yet been determined, 5G the true meaning of what 5G should look like, and when the network will be launched.
At present, many users using 4G to watch the video, consume a lot of bandwidth, so 5G will soon become an essential technology. With the promotion of research and development, concerning the definition of 5G network, availability, and application scenarios, we are a clearer understanding.
What is 5G? In nouns such as 3G, 4G and 5G, and g is the English word "generation" (x) abbreviation. Thus, the 5G is the fifth generation of mobile communications technology.
At present, 5G has not yet been finalized. Bill Smith, President of AT&T network operations (Bill Smith) that 5G will take place in 2018 to obtain accurate definitions, and the International Telecommunication Union (ITU) in 2019, 5G standards. Will be clearly defined in the standards, what kind of mobile communication technologies could be called "5G", as well as key pointers in 5G network, such as uplink and downlink rate.
However, we can still be based on preliminary tests of the communications industry to guess, 5G technology will be like in the future.
Simple, 5G speed will be faster, and power consumption will be lower than the 4G, resulting in a series of new wireless products. 5G networking will enable us Smartphone faster and will also produce more smart home devices and wearable computing devices.
5G speed how? May 4G network 5G network speed 40 times, enough to 8K resolution of 3D video, or within 6 seconds to download a 3D movie. (Through the 4G network, which takes 6 minutes of download time. )
For the user, however, laboratory tests and in reality there is always a big gap. In the current network of theoretical peak rate is only a dream, the actual available rate is much lower than the theoretical value.
5G technology in the process of research and development, Nokia is put into one of the largest manufacturers. The company believes that net, under network congestion, 5G the rate at which technology can bring about 100Mbps, the current 4G about 4 times.
5G is another feature of the network latency is very low, which means that network responds to user commands will be very fast. Therefore, sites, applications, video and messaging services will load faster.
5G Web form? Mobile device testing on 5G mainly based on UHF spectrum, such as the 73,000MHz spectrum. But the existing mobile communication network mainly uses 700MHz to 3500MHz.
A major advantage of using high frequency spectrum, to provide fast data transfer speeds, and drawback of electromagnetic wave transmission distance is very short, and easy to be obstruction. This means that we need to build millions of small base stations. Such a small base station might be deployed to every lamp post, every building, every family, every room.
This will lead to a series of questions. Operators how to handle all that data? Analysts at Gartner mobile infrastructure akexieyi·shaerma (Arkshay Sharma) says that some companies, such as Google's recent purchase of Alpental, is addressing the "return". But so far have not found a solution.
Therefore, 5G is more likely to complement 4G, rather than a direct replacement for 4G. In a building or in a crowded place, 5G is likely to bring the rate of improvement. But if driving on the highway, then 4G may be your only choice. At least it seems so.
5G the timing of the launch? This type of problem it is not possible to get answers. Widely believed that, during the 2018 Winter Olympic Games, Korea will introduce a 5G network, and large-scale deployment will not start until 2020.
However, Verizon said the company aims to introduce 5G technologies faster, is the earliest in the year 2017.
Taking into account the 5G faces a series of challenges in 2017, Verizon also is unlikely to mass deployment of 5G network. For example, the smart phone manufacturers need to control costs develop chips that support 5G signal.
