5G is different from 4G and older wireless standards. It is very fast, fundamentally reduces latency, and supports a large number of dense devices. What does this mean to you?

Each of the three important improvements mentioned above may not change the world by itself, but together they constitute a major shift in almost all industries. The wide application of 5G may even create some new industries.

From ultra-high-speed broadband to smart and self-driving cars to the vast Internet of things (IoT) network, 5G can act as a catalyst for a smarter, more connected world.

Broadband Internet is everywhere

Currently, FCC defines broadband as any Internet speed that is lower than 25mbps and higher than 3mbps, while 2010 is defined as 4mbps and 1mbps. However, both are much slower than the 5G, which is expected to be between 300 and 1000mbps or even higher.

5G can be used by homes or businesses through a fixed wireless access (FWA) connection. This means that the entire building has direct access to the 5G network from a nearby community, and in the building, every device can be connected through the existing Wi-Fi, including televisions, game consoles, mobile phones, desktops, laptops and other devices with 5G speeds.

For people in the center of a big city, or even in the suburbs, it is not uncommon to have a high-speed network. It is unusual for people to have a fast and reliable network connection.

When 5G is set on the edge of the city or farther away in rural areas, these residents can eventually upgrade to something better than satellites or dial-up Internet access, even if it is not as high-end as in densely populated areas.

Smart cars, cities and factories

Cars are already very smart, with smart car add-ons and built-in features such as automatically turning on lights and wipers, adaptive cruising, lane control, and even semi-autonomous driving. However, 5G will make a great leap forward in automotive technology. No, there are still no flying cars, but many amazing changes are coming.

Very similar to other changes brought about by 5G, ultra-reliability and high-bandwidth connectivity are the driving forces behind smart cities.

Intelligent traffic control is an example. When the whole city uses 5G network online and cars can communicate directly with other cars and traffic lights, the traffic signal will respond appropriately. One day, when there are no other vehicles around, you can wait at the stop light; the system will know when other vehicles are approaching fast enough to make sure there is a red light around you, otherwise it will allow you to cross the intersection seamlessly.

Cars, especially self-driving cars, need GPS to know exactly where they are. Although GPS is already very accurate and the latest generation of GPS chips are more accurate, direct car-to-car communication will perfect the entire experience, especially in terms of alternate routes and security.

Avoiding serial collisions and jams is another example of how 5G changes the way it drives. This happens when the car in front slows down until it stops to avoid an accident. Before we realized it, dozens of cars had lined up and it would take a long time for anyone to hit the road again.

Vehicle communication on the 5G network will not let it go that far, because each car will know the location of the other vehicles and will be informed in advance. Long before you, you need to create a new route or adjust the speed to keep the traffic smooth. If the area is blocked by a large number of other wireless communications, this always-on-line data cannot be transmitted smoothly or on time. 5G is built to support these huge data requirements.

As self-driving cars rely on high-bandwidth networks, rural areas will one day have access to broadband Internet, and smart cars will eventually be used in rural areas. This will provide safe means of transport for the disabled, the elderly and others who cannot drive themselves.

Another potential use case for smart 5G cities in terms of safety is directing traffic: parking or deceleration of buildings, trains, and other dynamic scenarios that require additional attention. If 5G-connected sensors are installed in the construction area, or if the school bus communicates directly with other vehicles, the driver can be alerted before entering the area where vigilance or complete parking is required.

Factories can benefit from 5G, not only in terms of automation, but also allow heavy machinery to operate remotely, making it easier to avoid dangerous situations. Immediate feedback is necessary, and 5G has a low latency to support it.

5G connectivity will also lead to smart farms, which will not only provide better crops, but also save money. The combination of ultra-accurate farm equipment and ground sensors means that farmers can update crop growth in real time, allowing them and even equipment to respond appropriately faster than ever before.

Add drones to the fully automated picture: crops can be watered when needed, animals can be fed on time, and you can sit and update things on time on your phone.

Everything is on demand.

On 4G networks or low-bandwidth Wi-Fi connections, you may experience delays when watching live TV, such as news or sports. Movies and programs may be buffered while waiting to download more data.

We can also continue to talk about other experiences, such as "on demand" online services. On the other hand, 5G is built to minimize the latency that causes these problems and to provide a huge pipeline where data can reach your device almost immediately.

Online games and video / audio chat are areas where you can see 5G features. Smooth games require a delay-free experience, and real-time feedback during Internet-based video calls is necessary, especially in professional settings.

5G also lays the foundation for new ways of communication. It is used to test 3D holographic calls, ranging from games to business phones and distance education.

Another 5G use case is in a Web application. While downloading any program is just as easy, and 5G makes the entire experience instant, you can free up storage space and avoid installation steps to prepare for streaming from a Web browser by using an Web-based application that has been set up.

In other words, 5G will bring a world where you need very little storage space on your phone, because everything, including your application, is instantly available from the cloud.

Further, imagine that the console works a few years longer than you do now, and you never need to upgrade. Instead of using a console with a new disk reader to support larger games or better hardware to handle the latest games, you can transfer all your processing power to a remote server and stream it to your device in real time.

The same is true for computers: provide it with basic hardware and access to a fast remote server, and through a 5G connection, all the data your computer needs can be transferred back and forth between ultra-high-speed server hardware.

Immersive AR and VR

Augmented reality (AR) and virtual reality (VR) are bandwidth-demanding technologies, and 5G can deal with them without problem. The immersive game played in AR and VR is one of the most watched use cases in 5G, but this is not what you can do with real-world hacking technology.

Sports is another area where VR will shine. For example, a football player can wear a head-mounted camera to provide his opinion in real time to anyone connected to the camera. Users can wear virtual reality helmets to get the players' first-hand experience at the scene.

Because augmented reality projects digital data into the real world around you by interrupting your field of vision, the number of applications is almost unthinkable. There are so many things that can be done with AR, and the ability of 5G to send messages to and from AR devices in almost real time is exciting about the future of the industry.

Some early, simple examples of 5G AR include projecting email and text messages into the room around you, creating multiple floating monitors to expand the display of your computer to enhance games, and setting up virtual HDTVs in your living room.

VR and AR helmets are already on the market, but 5G is the only way they can be used smoothly on mobile networks and with other web-enabled devices. In addition, with almost instant access to the cloud and everything that can be processed remotely, these devices can become thinner and smaller.

Intelligent medical treatment

Exchanging information with doctors or artificial intelligence systems is a top priority, especially in emergency situations. "on-demand doctors" is the development direction of 5G.

Imagine that in the near future, smart wearable devices can monitor not only your heart rate and rhythm, but also your blood sugar, hemoglobin, and so on. In an emergency, the last thing you want is that your device cannot communicate important data to your doctor because the connection is slow or crowded. However, with 5G, your wearable device will be able to quickly contact the server, update your health records, let your doctor check, or remind your family that your vital signs exceed safety levels and require immediate attention. 5G allows frequent data transmission at a reasonable speed without damaging the battery.

Similarly, it can send very high-resolution photos and videos anytime, anywhere on the 5G network, update the doctor's image and make a diagnosis at any time. In the future, doctors may be able to check remotely to save time and money.

At the same time, 3D printing and drones are also providing real-time. Both are relatively new industries, and 5G will help them enter a place where they can quickly access 3D design and order new materials in real time. Ambulance drones will soon be able to provide immediate care in remote or densely populated areas.

We have mentioned virtual reality, but it also has specific applications in the medical field. Students who have not yet undergone real surgery can use the VR helmet to understand the situation at the scene, or use AR to maintain the patient's vital signs at all times.

VR may one day be used in ambulance drones so that surgeons or health care professionals can advise patients remotely. Virtual reality requires very low latency and a lot of bandwidth, which is brought about by high-speed 5G networks.

5G seems to be exactly what we need to allow remote professionals to operate on someone around the world. Imagine that there are only a few doctors in a small hospital, a patient needs to be operated on immediately, and only a few people in the world can complete the operation. The extremely low delay of 5G means that surgery can be performed in real time hundreds or even thousands of miles away.

Telemetry is another 5G use case that involves transferring data from a device to a monitoring station that can interpret or store information. The huge bandwidth capacity of 5G opens up possibilities for other types of telemeters, either those that can avoid data compression to receive results faster, or ultra-sensitive telemeters that respond to real-time data.

Another 5G medical transformation is digital record keeping and file transfer. Many hospitals try to maintain digital health records without using 5G, but as the speed increases, machines throughout the building can move large amounts of data faster.

MRI is such a machine that takes a long time to send large scanned images and can easily delay doctors' visits to other patients and hide important information from technicians who need to read scanned images.

5G opens up a whole new scene in which hospital machines can transfer data to the right place more quickly, not only benefiting other patients and the entire hospital, but also potentially saving lives.

Breaking the language barrier is another 5G medical use case, which, of course, extends to areas other than health care that are difficult to communicate, especially in emergency situations. Translation is not always localized, so it is important to have a clear and immediate dialogue between him or her and the patient in order to convey diagnostic information or request information from the patient or doctor.

Better law enforcement

A 5G police drone with a high-definition camera can provide low-latency (basically real-time) tracking, allowing real-time monitoring by operators in the car or behind the station. These types of drones can also be used for other things, such as monitoring other areas that police cars and police cars cannot reach, or responding to calls faster than ground drivers.

Police-driven drones also allow cities to deploy drones to monitor citizens on a regular basis. Some people see this as a dangerous invasion of privacy, but the technology is mature and 5G technology will make it more likely that drones will be deployed.

Another area where 5G can keep cities safe is through cameras that are always on. The police wear these cameras to track what they see. 5G allows video / audio streams to be stored in remote locations in real time to prevent data loss or tampering.

Peer to peer (P2P) communication

P2P connection means that two or more devices communicate directly and transmit data back and forth without using a server.

Currently, most communications and data transfers work by uploading information to the server, and then others can download it from the same server. This is how most of the Internet works. It is very effective and provides a seamless experience.

For example, when you send an atlas to a friend, it is usually done through an e-mail or file sharing application. This allows you to upload data to an e-mail server or a data sharing service server so that your friends can download photos quickly (because the server supports fast upload speed).

5G is changing P2P connections because your phone and computer can do the same thing, not just get faster uploads. The minimum upload speed per 5G unit is 10 Gbps (1.25 gigabytes per second), which means that under ideal conditions, users can transfer 1.25 GB of data per second between devices. This is much faster than what is widely used today.

With such a fast upload speed on your terminal, others can also get a super fast download speed of 5G, which means that other people can download data from you as fast as you upload it.

P2P can be used in many forms, such as making phone calls in smart cities, transferring files, transmitting information between vehicles, automating factory equipment, and interconnecting smart sensors in homes, cities, farms, and so on.
