When we are immersed in the 4G network of high-speed, ridicule 4G network charges, the next generation of mobile communications network--5g has been published.

5G Network as the next generation of mobile communications network, the highest theoretical transmission speed of dozens of GB per second, which is faster than the current 4G network transmission speed hundreds of times times, the entire Super High-definition film can be downloaded within 1 seconds.

Samsung Electronics announced May 13, 2014 that it had pioneered the first mobile transmission network based on 5G core technology, and said it would launch a commercial extension of the 5G network by 2020.

Technical principle

Samsung Electronics through the research and experiments show that in the 28GHz ultra-high frequency segment, at 1Gb per second speed, the transmission distance in the 2Km range of data transmission successfully achieved. Prior to this, no enterprise or organization in the world has developed more than 6GHz of UHF segment to achieve more than GB per second data transmission technology, because it is difficult to solve the UHF wave length of data loss is large, transmission distance short and other difficult problems.

Samsung Electronics utilizes the adaptive Array transmission technology of 64 antenna units, makes the long-distance transmission of the radio wave possible, and can trace the position of the user terminal in real time, and realize the exchange of data on and off. The success of high frequency data transmission technology not only guarantees the higher transmission speed, but also solves the problem that the resources of mobile communication band are nearly exhausted.

Progress in research and development

Samsung Electronics announced May 13, 2014 that it had pioneered the first mobile transmission network based on 5G core technology, and said it would launch a commercial extension of the 5G network by 2020.

2020 Samsung Electronic program to achieve the commercialization of the technology as a goal, the overall development of 5G mobile communication core technology. With the development of Samsung Electronic technology, the fifth generation of mobile communication technology in the world will be more active, the introduction of international standards and commercialization will also accelerate.

Main function

The primary goal of the 5G network is to keep end users networked. The 5G network will support much more than smartphones in the future--it also supports smart watches, wrist bands, smart home appliances such as bird-house thermostats. 5G network refers to the next generation wireless network. 5G Network will be the real upgrade of 4G network, it and basic requirements and different from today's wireless network

Transfer rate

5G Network as the next generation of mobile communications network, the highest theoretical transmission speed of dozens of GB per second, which is faster than the current 4G network transmission speed hundreds of times times, the entire Super High-definition film can be downloaded within 1 seconds. With the advent of 5G technology, the era of sharing 3D movies, games and hyper-quality (UHD) shows with intelligent terminals has come to us.

Its 5G network has successfully reached 1Gbps under the 28,000 MHz (GHz) band, compared to the current fourth generation long-term evolution (4G LTE) service with a rate of only 75Mbps. The previous transmission bottleneck was widely considered a technical problem in the industry, while Samsung Electronics used 64 antenna Units Adaptive array transmission technology to solve the problem.

The future 5G network transmission rate of up to 10Gbps, which means that mobile phone users in less than a second time to complete a high-definition movie download.

5G network means super fast data transmission speed. Samsung announced in May 2013 that its upcoming 5G technology could transmit more than 1G of data per second. In contrast, the relatively fast LTE network now transmits around 60M of data per second, about the equivalent of 0.05G. The speed of such a wireless network will be much faster than you can experience with any smartphone. Google says it can download a full HD movie in less than two minutes, even at 1G per second.

Smart Devices

The biggest improvement seen in the 5G network is its flexibility to support a variety of different devices. In addition to supporting mobile phones and Tablet PCs, 5G networks will also need to support wearable devices such as fitness trackers and smart watches, smart home appliances such as bird-house thermostats.

Supporting countless devices in a given region is the design goal of scientists. In the future, everyone will need to have 10-100 units for their services. But scientists are now having a hard time figuring out how much data capacity is needed to support all these devices.

Network links

5G networks not only support more data, but also support more usage rates. 5G network, improving End-to-end performance will be another major issue. End-to-end performance is the state of being connected between a smartphone's wireless network and a server that searches for information.

When you are sending text messages or browsing the Web, when watching network video, if you find that video playback is not smooth or even stagnant, it is likely because the end to end network connectivity is poor.

Battery life

Next-generation wireless networks will also bring a big boost in battery life for smartphones and mobile devices. Because there are a lot of smaller tasks that require applications to run non-stop. The e-mail application sends requests to the server over and over again to check for new e-mail messages.

There are a number of applications that are constantly sending short messages, which, though short, will continue to erode the phone's battery power over time. The team at Bell Labs has a task of finding a better way to process these requests. If I can handle this information, I can dramatically improve the battery life of my tablet.

Development prospects

Samsung's replacement technology breakthrough on the 5G network will bring vitality to the global 5G Network research and development, promote its commercialization process, and contribute to the development of 5G Network Technology International standards.

To seize the future market, the world has been competing for a number of countries to develop 5G network technology, China and the European Union are investing a lot of money in the development of 5G network technology.

China and the European Union have invested a lot of money and research and development in the development of 5G network technology in many countries around the world. Samsung's technological breakthroughs in the 5G network will further aggravate the global 5G Network Development Competition and accelerate its commercialization process. Samsung Electronic DMC Research experts said that with the rapid speed of mobile network data transmission, the quality of more than 4 times times the full HD-8 times times the Super HD (UHD) image and 3D stereo image production industry will usher in a new era of development.

Technical Test

In July 2014, Ericsson announced that it had the highest transmission speed of 5Gbps in a wireless test of 5G wireless technology. The wireless transmission speeds up to 5Gbps, means is 250 times times faster than today's LTE connection standard, marks the wireless transmission speed to create the new record. This transmission rate, whether for smartphones, automobiles, medical and other equipment, will benefit from this. The network reaches 5Gbps speed, download a 50GB movie only need 80 seconds, and this speed is Google Fiber 1Gbps transmission speed of 5 times times.

But at present the 5Gbps transmission speed is only the data of the laboratory ideal state, but the actual commercial deployment waits until 2020.

It is reported that Ericsson has been with Japan's NTT Docomo, South Korea's SK Telecom launched 5G network test. Ericsson said that, given the current high prevalence of LTE networks in the North American market, the 5G network may be the first to reach the market, but up to now, the North American market has no operators to make any commitment to the 5G network.
