5G Network


The 5G network is the fifth generation mobile communication network, and its peak theoretical transmission speed can reach 1GB every 8 seconds, which is hundreds of times faster than the transmission speed of 4G network. For example, a 1G movie can be downloaded in less than 8 seconds.

Technical Principle

Through research and experiments, Samsung Electronics has successfully realized data transmission with a transmission distance of 2Km at a speed of more than 1Gb per second in the ultra-high frequency band of 28GHz. Previously, no company or organization in the world developed data transmission technology above the Gb level in the ultra-high frequency band above 6 GHz. This is because it is difficult to solve the data loss caused by the UHF wavelength band and the transmission distance is short. problem.

Samsung Electronics uses adaptive array transmission technology of 64 antenna elements to enable long-distance transmission of radio waves, and can track the position of the user terminal in real time to realize data download and exchange. The success of the ultra-high frequency band data transmission technology not only ensures a higher data transmission speed, but also effectively solves the problem that the mobile communication band resources are almost exhausted.


The Main Function

The main goal of 5G networks is to keep end users connected to the Internet. 5G networks will support more than just smartphones in the future - it also supports smart watches, fitness wristbands, and smart home devices such as the nest-type indoor thermostat. The 5G network refers to the next generation wireless network. The 5G network will be a truly upgraded version of the 4G network, and its basic requirements are different from wireless networks.


Transmission Rate

Its 5G network has successfully reached 1Gbps in the 28 GHz band, compared to the current 4th generation Long Term Evolution (4G LTE) service with a transmission rate of only 75Mbps. Previously, this transmission bottleneck was widely recognized as a technical problem in the industry, and Samsung Electronics solved the problem by using adaptive array transmission technology of 64 antenna elements.

In the future, the transmission rate of 5G networks can reach 10Gbps, which means that mobile phone users can download a high-definition movie in less than one second.

5G networks mean ultra-fast data transfer speeds. In May 2013, Samsung announced that its upcoming 5G technology can transmit more than 1G of data per second. In contrast, a relatively fast LTE network can transmit approximately 60M of data per second, which is approximately equivalent to 0.05G. This wireless network will be much faster than any smartphone you experience. Google claims that even at 1G per second, it can take less than two minutes to download a full HD movie.


Smart Device

The biggest improvement seen in 5G networks is its flexibility to support a wide range of devices. In addition to supporting mobile phones and tablets, 5G networks will also need to support wearable devices such as fitness trackers and smart watches, smart home devices such as nesting room thermostats.

Supporting countless devices in a given area is the design goal of scientists. In the future, everyone will need to have 10 to 100 devices to serve them. But it's hard for scientists to figure out how much data capacity they need to support all of these devices.


Internet Connection

5G networks not only need to support more data, but also support more usage. Improving end-to-end performance in 5G networks will be another major issue. End-to-end performance refers to the state of the connection between the wireless network of the smartphone and the server that searches for information.

When sending a text message or browsing a web page, if you find that the video playback is not smooth or even stagnant when watching the network video, it is probably because of the poor end-to-end network connection.


Battery Life

Next-generation wireless networks will also bring a significant drop in battery life for smartphones and mobile devices. Because there are many smaller tasks that require the application to run without stopping. The email application will repeatedly send the request information to the server to check if a new email arrives.

There are a lot of applications that constantly send small messages, which are short, but they continue to erode the phone's battery power over time. One of the tasks at Bell Labs' team is to find a better way to handle the information on these requests. If we can handle this information, we can greatly improve the battery life of the tablet.
