At the Global Mobile Broadband Forum (MBBF), Huawei's rotating president - Ken Hu had many useful sharings around the development and utilization of 5G for digital transformation.

After 5 years of commercial deployment, there are now more than 176 5G networks globally, serving more than 500 million subscribers.

In the consumer sector, the average download speed of 5G is about 10 times faster than 4G, which has spurred widespread adoption of this technology in many fields, such as virtual reality, broadcasting. 360 degree online...

In the enterprise sector, there have been more than 10,000 projects exploiting B2B applications of 5G worldwide. 5G applications in industries such as manufacturing, mining, and ports have passed the pilot stage and are being replicated on a large scale.

Taking advantage of 5G networks will bring drastic changes and have long-lasting effects, such as supporting the acceleration of digital transformation, applications with climate change, helping to reduce many problems, speed Faster internet access...

Mr. Ken Hu said that 5G brings many opportunities to the industry, but they also create a new challenge. As a result, businesses need to get their networks, devices, and assets ready for the explosive growth in Augmented Reality (XR).

To support a smooth cloud-based XR experience, networks need to deliver faster download speeds of 4.6 Gbit/s with latency greater than 10 milliseconds.

To enrich the content ecosystem, Mr. Hu called on the industry to provide cloud platforms and tools that simplify content development, which is notoriously difficult, difficult and expensive.

Additionally, carriers need to strengthen their networks and develop new capabilities to be 5GtoB-ready. Networking is key for 5G applications for industrial use, so carriers need to continue to improve network capabilities such as uplink, positioning, and sensing.

To promote the wider adoption of 5G across industries, it is also important to develop industry-specific telecommunications standards.

In China, carriers together with their industry partners have begun working on standards for 5G adoption in industries such as coal mining, steel and digital energy, and this will help accelerate the adoption of 5G. more used in this area.

In addition, with this development push, digital technology can help reduce at least 15% of global carbon emissions, which is a signal that environmental protection always comes first.

The 2021 Global Mobile Broadband Forum is hosted by Huawei, together with industry partners GSMA and the SAMENA Telecommunications council. The forum brings together mobile carriers, industry leaders and ecosystem partners from around the world to discuss how to maximize the potential of 5G and propel the mobile industry forward.

Are you curious about what 5G network is? Simply put, this is the 5th generation of mobile networks. Each generation will bring the most suitable networking capabilities and will be upgraded gradually. 5G technology appeared in 2017 but it will still take some time to appear more popular in countries. As the network following the 4G generation, 5G is expected to have improved speeds than its predecessors. Today, let's take a quick look at this new generation of network!

Advantages of 5G network

Talking about the advantages of the 5G network, it will definitely help the network speed to be faster than the 4G network. Users can download a movie in just a few seconds, because the speed can reach 10Gbps or even higher. Especially, even in the outside coverage area, the speed still reaches from 1 to several hundred Mbps.

But so far nothing is certain as there is also information about when 4H LTE will launch. Actual speed is only 5~12Mbps download and 2~5Mbps upload. The previous parachute was expected to 300Mbps. But really, 5G network is still worth looking forward to because in addition to high bandwidth. The 5G network also offers many good communication features compared to the previous 4G network.

Benefits of 5G network bring to life

Talking about the first change you will feel is the connection and download speed. Besides, network communication latency is also significantly reduced. It can be compared like this: for 4G networks there is a maximum delay of 50 milliseconds. Then 5G has reduced it to 4 milliseconds, helping you connect faster.

And it is predicted that in the next few years, 5G networks will be even faster. When it was planned to exploit the frequencies beyond 6GHz. It is even predicted that when users use the 5G network, they will no longer feel the delay, bringing many benefits to users using the network. However, along with the benefits, there is also a high cost that is obvious.

For today's modern life, the mobile network is not only encapsulated in making calls. But also have to connect to the internet to work and more smart devices need to connect to the internet. The trend of connectivity is always evolving, so it is necessary for a mobile network to always improve to meet the needs of users. That is also the benefit and changes 5G network will bring later.

Obviously, the future of 5G is coming faster than we expected. So let's look forward to the improvement of this new mobile network.

5G networks can handle thousands of times more traffic, and it offers speeds up to 10 times faster than 4G LTE networks. Imagine being able to download an HD movie in under a second. 5G networks will be the foundation for virtual reality services, autonomous driving, IoT and many other services that we have not yet imagined.

So what are the technological characteristics of 5G networks? Let's take a look at five emerging technologies that have recently emerged as the foundation of 5G networks: Milimeter waves, Small Cell, Massive MIMO, Beamforming and Full Duplex

1. Millimeter waves

Smartphones and other electronic devices in our homes operate on specific frequencies on the radio frequency spectrum, usually frequencies below 6GHz. These frequencies are becoming more and more crowded. Carriers can only carry a certain amount of data on the same radio frequency band. As more devices go online at the same time, we will see service become slower and more connections dropped.

The solution is to expand the frequency range used for devices. The researchers are experimenting with broadcasting on shorter millimeter waves at frequencies between 30GHz and 300GHz. This spectrum has never been used before for mobile devices. With such an opening means more bandwidth for all users.

One issue to consider, however, is that millimeter waves cannot travel through buildings or obstacles and they tend to be absorbed by vegetation and rain. To solve this problem, 5G networks need a second technology called Small Cell

2. Small Cell

Today's wireless networks rely on high-powered base stations to transmit signals. High-frequency millimeter waves are often difficult to navigate through obstacles. That means if you move behind an obstacle, you will lose signal.

Small Cell solves this problem by using thousands of low-power cell towers. These stations are much closer together than traditional broadcast stations, and they are arranged to transmit signals around obstacles. This is especially useful in large cities because when a user moves behind an obstacle, his or her smartphone automatically switches to the new base station and allows to keep the connection intact.

3. Massive MIMO

MIMO stands for Multiple Input Multiple Output (multiple input and multiple output). Today's 4G station has about 12 antenna ports that handle the traffic, while Massive MIMO stations can support hundreds of ports. Using Massive MIMO can increase the capacity of the network by 22 times or more.

However Massive MIMO comes with its own problems. Cellular antennas broadcast information in all directions at once, and those crossing signals can cause serious interference. To solve this problem, beamforming technology is mentioned.

4. Beamforming

Beamforming is like a traffic control system for mobile signals. Instead of broadcasting in all directions, it allows the base station to send data centrally to a specific user. This prevents interference and broadcasts more efficiently. Stations can handle multiple incoming and outgoing data streams at the same time.

Assume the user is in a cluster of buildings and makes a phone call. That user's signal radiates around buildings and mixes with signals from other users in the same area. The Massive MIMO station receives all of these signals, tracks their arrival time and direction, uses signal processing algorithms to shape exactly where each signal is emitted, and plots a good path to each device. .

5. Full Duplex

If we have ever used walkie talkies, we all know that in order to communicate, users have to take turns listening and talking and that is considered a limitation. Mobile stations now operate in a similar manner. A basic antenna can only do one job at a time or transmit or receive signals.

Full duplex allows simultaneous transmission and reception in the same frequency band, thus, in theory, doubling the system throughput.
