The future for 5G mobile technology in Vietnam

# data[].attributes.attachment_link.readable_text
After years of anticipation-and a considerable amount of hype-fifth generation ( 5G) wireless networks are finally becoming a reality. 5G could effect our lives more dramatically than any technology shift since the internet itself, because 5G enables us to realize the potential of a fully connected world.

The reasons? Speed, low latency and ubiquity.

Mature 5G networks will operate at higher frequencies and shorter ranges than 4G, relying on a dense infrastructure of shoebox-sized "towers" every few hundred feet. That allows them to support billions of devices, with almost no latency, at speeds up to 20 times faster than 4G. 5G antennas also consume less power, making the protocol better for connecting small, battery-powered Internet of Things ( IoT) devices.

As an enabling technology, 5G could effect our lives in five key ways.

1. Smart Cities

According to the National League of Cities, two-thirds of U.S. municipalities have invested in smart city technology. For example, San Diego installed smart lighting systems that automatically dim when no one's nearby, saving nearly $2 million a year in electricity costs. Pittsburgh is replacing 36,000 streetlights with LEDs that contain sensors to monitor air quality. South Bend, Indiana, installed sensors inside manhole covers that redirect waterflow when sewer levels get too high. After San Francisco installed gunshot-detecting microphones in high crime neighborhoods, it reported a 35 percent decrease in incidents where shots were fired.

Upgrading to 5G will allow cities to handle data from millions more IoT devices and install low-power sensors that can last years without needing replacement. This will expand their ability to intelligently manage traffic flow, air quality, power use, public safety and more. A 2017 Accenture Strategy report predicts that using 5G networks to manage traffic and power could save cities $160 billion.

2. The World of Work

Perhaps 5G's broadest impact will be industrial and commercial IoT. Location beacons already transform how goods move from inventory through shipping and delivery. ABI Research predicts that more than 500 million objects will be tracked by 2023. Precision agriculture uses soil sensors and airborne cameras to identify crop disease, determine when to water and reduce pesticide usage. Smart factories deploy connected robots to automate dangerous and/or repetitive jobs.

All of these changes will increase exponentially once ultra-fast wireless networks are in place, accommodating an estimated 125 billion IoT devices by 2030.

"IoT will be a significant driver of what's coming to be known as 'the fourth industrial revolution,'" says Greg Bollella, VMware vice president in the office of the CTO.

3. Driverless Cars

According to the National Highway Traffic Administration, nearly 95 percent of traffic accidents are caused by human error. Removing humans from behind the wheel could save up to 1.25 million lives every year.

But for driverless cars to become fully autonomous, they'll need to communicate with the cars around them to avoid accidents and minimize congestion. They'll need to talk to sensors embedded in traffic lights, road signs, and the pavement to navigate more safely. And they'll need to get responses instantly-which is where low-latency 5G networks come in.

"Only fast networks, such as 5G, can support millisecond-level latencies," notes Dr. Kevin Curran, a professor at Ulster University in Northern Ireland, and group leader for the Ambient Intelligence Research Group. "We're not far from driverless vehicles sharing our roads and one day dominating them, but first we need to invest in the infrastructure."

Once driverless infrastructure is in place, the streets may become less crowded and the air less polluted. With fully autonomous vehicles, fewer people will own cars and ride-sharing could become more common. The Boston Consulting Group predicts that this will slash the number of vehicles on city streets by 60 percent and tailpipe emissions by 80 percent.

4. Telemedicine

Trips to the doctor's office may become as rare as house calls, thanks to virtual visits enabled by low-latency, HD-quality wireless networks. Wearable or implanted medical devices will capture your vitals and transmit them to health care providers, allowing them to detect early warning signs of heart attacks, strokes, or other life-threatening events.

"5G will open the door to important developments in personalized, anywhere, anytime medicine," says Dr. David Teece, professor at UC Berkeley's Haas School of Business.

High-speed wireless networks will also enable telesurgery, where specialists in one hospital control equipment in another facility hundreds of miles away. That day may be closer than you think. In January, a surgeon in China successfully removed part of a pig's liver from 30 miles away using a 5G connection.

5. Virtual Spaces

Thanks to 5G's high-bandwidth and low latency, augmented and virtual reality could finally become a practical reality. VR telepresence apps will allow colleagues in distant cities to work "side by side," or sports fans to experience the roar of the Super Bowl crowd from the comfort of their couches. We'll virtually roam shopping districts in Tokyo during lunch breaks and have the goods shipped to our homes.

All these changes won't happen overnight. While the major carriers are busy installing limited versions of 5G in cities around the globe, devices capable of accessing 5G networks are just starting to appear, and ultra-high-speed deployments are still several years away.

It took 10 years for 4G to become the dominant cellular technology, and 5G might take even longer. But once it's fully in place, we'll wonder how we ever lived without it.

WHAT IS 5G?

5G is the 5th generation of mobile networks, a significant evolution of todays 4G LTE networks. 5G has been designed to meet the very large growth in data and connectivity of today's modern society, the internet of things with billions of connected devices, and tomorrow's innovations. 5G will initially operate in conjunction with existing 4G networks before evolving to fully standalone networks in subsequent releases and coverage expansions

In addition to delivering faster connections and greater capacity, a very important advantage of 5G is the fast response time referred to as latency.
Latency is the time taken for devices to respond to each other over the wireless network. 3G networks had a typical response time of 100 milliseconds, 4G is around 30 milliseconds and 5G will be as low as
1 millisecond. This is virtually instantaneous opening up a new world of connected applications.

WHAT WILL 5G ENABLE?

5G will enable instantaneous connectivity to billions of devices, the Internet of Things (IoT) and a truly connected world.

5G will provide the speed, low latency and connectivity to enable a new generation of applications, services and business opportunities that have not been seen before.

There are three major categories of use case for 5G:

1. Massive machine to machine communications - also called the Internet of Things (IoT) that involves connecting billions of devices without human intervention at a scale not seen before. This has the potential to revolutionise modern industrial processes and applications including agriculture, manufacturing and business communications.

2. Ultra-reliable low latency communications - mission critical including real-time control of devices, industrial robotics, vehicle to vehicle communications and safety systems, autonomous driving and safer transport networks. Low latency communications also opens up a new world where remote medical care, procedures, and treatment are all possible

3. Enhanced mobile broadband - providing significantly faster data speeds and greater capacity keeping the world connected. New applications will include fixed wireless internet access for homes, outdoor broadcast applications without the need for broadcast vans, and greater connectivity for people on the move.

For communities, 5G will enable the connection of billions of devices for our smart cities, smart schools and smart homes, smart and safer vehicles, enhance health care and education, and provide a safer and more efficient place to live.

For businesses and industry, 5G and IoT will provide a wealth of data allowing them to gain insights into their operations like never before. Businesses will operate and make key decisions driven by data, innovate in agriculture, smart farms and manufacturing, paving the way for cost savings, better customer experience and long term growth.

New and Emerging technologies such as virtual and augmented reality will be accessible by everyone. Virtual reality provides connected experiences that were not possible before. With 5G and VR you will be able to travel to your favourite city, watch a live football match with the feeling of being at the ground, or even be able to inspect real estate and walk through a new home all from the comfort of your couch.

5G will keep us connected in tomorrow's smart cities, smart homes and smart schools, and enable opportunities that we haven't even thought of yet.

5G Enhanced Mobile Broadband and IoT will revolutionise agriculture and farming.

WHEN DID 5G LAUNCH?

Initial 5G services commenced in many countries in 2019 and widespread availability of 5G is expected by 2025.

top

WHAT ARE THE FIRST APPLICATIONS FOR 5G?

Fixed wireless access for homes and enhanced mobile broadband services are the first applications using new 5G phones, tablets, wireless access modems and hot spots.

top

WHAT DO 5G DEVICES OFFER?

The prime benefits of 5G devices will be significantly faster speeds in data access, downloading and streaming content. In addition, 5G devices will have increased computing power and make use of the lower latency, meaning that the devices will enjoy virtually instantaneous connections to the network, as well as greater connectivity when on the move due to the use of advanced antenna beam steering.
top

WHAT DEVICES ARE AVAILABLE FOR 5G?

Mobile handsets, tablets and hot spots equipped with 3G, 4G and 5G connectivity were launched in 2019 and low latency and widespread machine to machine applications using 5G will be developed in the coming years.

HOW DOES 5G WORK?

Most operators will initially integrate 5G networks with existing 4G networks to provide a continuous connection.

5G network architecture illustrating 5G and 4G working together, with central and local servers providing faster content to users and low latency applications.

A mobile network has two main components, the 'Radio Access Network' and the 'Core Network'.

The Radio Access Network - consists of various types of facilities including small cells, towers, masts and dedicated in-building and home systems that connect mobile users and wireless devices to the main core network.

Small cells will be a major feature of 5G networks particularly at the new millimetre wave (mmWave) frequencies where the connection range is very short. To provide a continuous connection, small cells will be distributed in clusters depending on where users require connection which will complement the macro network that provides wide-area coverage.

5G Macro Cells will use MIMO (multiple input, multiple output) antennas that have multiple elements or connections to send and receive more data simultaneously. The benefit to users is that more people can simultaneously connect to the network and maintain high throughput. Where MIMO antennas use very large numbers of antenna elements they are often referred to as 'massive MIMO', however, the physical size is similar to existing 3G and 4G base station antennas.

The Core Network - is the mobile exchange and data network that manages all of the mobile voice, data and internet connections. For 5G, the 'core network' is being redesigned to better integrate with the internet and cloud based services and also includes distributed servers across the network improving response times (reducing latency).

Many of the advanced features of 5G including network function virtualization and network slicing for different applications and services, will be managed in the core. The following illustration shows examples of local cloud servers providing faster content to users (movie streaming) and low latency applications for vehicle collision avoidance systems.

Example of a local server in a 5G network providing faster connection and lower response times

Network Slicing - enables a smart way to segment the network for a particular industry, business or application. For example emergency services could operate on a network slice independently from other users.

Network Function Virtualization (NVF) - is the ability to instantiate network functions in real time at any desired location within the operator's cloud platform. Network functions that used to run on dedicated hardware for example a firewall and encryption at business premises can now operate on software on a virtual machine. NVF is crucial to enable the speed efficiency and agility to support new business applications and is an important technology for a 5G ready core.

5G WORKING WITH 4G

When a 5G connection is established, the User Equipment (or device) will connect to both the 4G network to provide the control signalling and to the 5G network to help provide the fast data connection by adding to the existing 4G capacity.
Where there is limited 5G coverage, the data is carried on the 4G network providing the continuous connection. Essentially with this design, the 5G network is complementing the existing 4G network

top

HOW DOES 5G DELIVER CONTINUOUS CONNECTION, GREATER CAPACITY, AND FASTER SPEED AND RESPONSE TIMES?

Better Connection - always connected

5G networks are designed to work in conjunction with 4G networks using a range of macro cells, small cells and dedicated in-building systems. Small cells are mini base stations designed for very localised coverage typically from 10 metres to a few hundred metres providing in-fill for a larger macro network. Small cells are essential for the 5G networks as the mmWave frequencies have a very short connection range.

Increased Spectrum - greater capacity, more users and faster speed

In many countries the initial frequency bands for 5G are below 6 GHz (in many cases in the 3.3-3.8 GHz bands) and similar frequencies to existing mobile and Wi-Fi networks. Additional mobile spectrum above 6 GHz, including the 26-28 GHz bands often referred to as millimeter (mm) Wave, will provide significantly more capacity compared to the current mobile technologies. The additional spectrum and greater capacity will enable more users, more data and faster connections. It is also expected that there will be future reuse of existing low band spectrum for 5G as legacy networks decline in usage and to support future use cases.

The increased spectrum in the mmWave band will provide localised coverage as they only operate over short distances. Future 5G deployments may use mmW frequencies in bands up to 86 GHz.

Other radio services (TV, Wi-Fi, Fixed links & Satellite) are shown for reference. Additional information on the Electromagnetic Spectrum is available here

Massive MIMO

multiple element base station - greater capacity, multiple users, faster data

5G will use 'massive' MIMO (multiple input, multiple output) antennas that have very large numbers of antenna elements or connections to send and receive more data simultaneously. The benefit to users is that more people can simultaneously connect to the network and maintain high throughput.
The overall physical size of the 5G massive MIMO antennas will be similar to 4G, however with a higher frequency, the individual antenna element size is smaller allowing more elements (in excess of 100) in the same physical case.
5G User Equipment including mobile phones and devices will also have MIMO antenna technology built into the device for the mmWave frequencies.

4G sector base station and 5G base station with a new multi element massive MIMO antenna array. The overall physical size of the 5G base station antenna is expected to be similar to a 4G base station antenna.

MIMO - Beam Steering
Beam steering is a technology that allows the massive MIMO base station antennas to direct the radio signal to the users and devices rather than in all directions. The beam steering technology uses advanced signal processing algorithms to determine the best path for the radio signal to reach the user. This increases efficiency as it reduces interference (unwanted radio signals).

Massive MIMO antenna and advanced beam steering optimises EMF and increases efficieny.

Lower Latency - Faster response times

Lower latency with 5G is achieved through significant advances in mobile device technology and mobile network architecture.

5G Network - Mobile Network Architecture Significant changes in both the Core Network (Core) and Radio Access Network (RAN) are required to deliver low latency.

Core Network Changes With the redesigned core network, signalling and distributed servers, a key feature is to move the content closer to the end user and to shorten the path between devices for critical applications. Good examples are video on demand streaming services where it is possible to store a copy or 'cache' of popular content in local servers, so the time to access is quicker.

Radio Access Network Changes To achieve the low latency, the Radio Access Network (RAN) will need to be re-configured in a manner that is highly flexible and software configurable to support the very different characteristics of the types of services that the 5G system envisages.

Low latency and high reliability over the air interface requires new radio techniques to minimise the time delays through the radio within a few TTIs (time transmit intervals) along with robustness and coding improvements to achieve high degrees of reliability (e.g. one message is delayed or lost in every billion).

Implementing a virtual, dynamic and configurable RAN allows the network to perform at very low latency and high throughput, but it also allows the mobile network to adjust to changes in network traffic, network faults and new topology requirements.

What will be re-configured? The new architecture will exist as a 4G/5G split RAN where the user plane (5G) and the control plane (4G) are separate. This requires the separation of general purpose hardware and specialised network hardware. The functionality of general purpose hardware (nodes) are suitable for network functions virtualisation (NFV), where the specialised hardware in the RAN will become dynamically configurable.
