What will change with next-generation communication technology 5G? Explain the advantages and disadvantages
Next-generation communication technology 5G. What does this new communication standard that will service in the very near future bring to us? I will explain what should be known about 5G now, what will change with 5G, what benefits will be obtained, and what will be disadvantageous
What will change? What is next-generation communication technology 5G?
5G (5th generation mobile communication system) is a new communication standard and technology that replaces 4G, which is currently the mainstream in Japan. The development of international standard specifications has progressed through the 3GPP (Third Generation Partnership Project), which involves the participation of standardization organizations around the world, and the countdown to the start of commercial services has begun.
Since the advent of mobile phones in the 1980s, communication standards have changed generations about every 10 years. In contrast to 4G (including LTE, also called 3.9G), which boosted the explosive spread of smartphones, 5G is said to be a communication standard that connects more diverse devices and applications.

The effective speed of 5G reaches 10Gbps, which is about 100 times that of 4G. But it ’s not just “super-fast”. Combined with the three features of "multiple simultaneous connections" that can be connected to a large number of terminals of 1 million per square km, and "ultra-low latency" of about 1 millisecond (0.001 seconds), which is about 1/10 of the conventional As a result, 5G is expected to become the foundation of “IoT” that connects everything to the Internet.
In addition to these three features, “network slicing” is also attracting attention from various industries as an important 5G technology. This is a term that means network partitioning, which means that different (virtual) networks can be constructed depending on what the service requires.
For example, some services can be used as high-speed and large-capacity networks, while other services can be used as low-latency and high-reliability networks..
Background to the need for next-generation communication technology 5G
Let's take a look at the case of autonomous driving as a concrete example of why 5G will become the ICT platform in the IoT era.
In an automated driving system, communication delays are literally fatal. For example, if the brake is applied by remote operation by the central control center, for example, if a delay of 0.1 second occurs, a car that was running at 60 km / h will stop after running about 1.7 meters. This is not enough in situations where sudden braking is required. However, in 5G, while suppressing the data transfer delay in the wireless section to 1 millisecond or less, further adding bottleneck elements such as communication between base stations and data processing of terminals, we are actually driving the car It is thought that remote control will be possible with a sense that does not change so much.
In addition, functions such as ultra-high speed and multiple simultaneous connections are essential for exchanging data with in-vehicle sensors in each running car and for sending and receiving high-definition video and map information. To realize an automatic driving system, the conventional communication line clearly lacks specifications.
In addition, smartphone functionality will also improve with the spread of 5G. For large-scale sports events such as the Tokyo Olympics, it is expected to provide services that allow high-definition video information such as multi-angle and replay to be played back in real time to the terminals of users who visit the stadium. A new 5G communication environment is indispensable in order to enable a large number of simultaneous data communications for tens of thousands of terminals in a certain area.
Advantages and disadvantages of next-generation communication technology 5G
In addition to automated driving systems and large-scale sporting events, what benefits will 5G bring to our lives? On the other hand, I am worried about the disadvantages. Let's list the advantages and disadvantages of 5G.
merit
Higher speed, larger capacity, lower latency, and improved reliability make it easier to use the Internet on your smartphone. There will be no problem even if many people stream 4K videos using smartphones at the same place.
In the IoT world, you will also benefit from 5G. Other than the automatic driving system, “remote surgery” performed by a remote doctor operating a robot arm will have a great impact on society. In addition, the “Smart Factory” that can improve the productivity by connecting the equipment and production lines in the factory to the network and reflect the options that the consumer wants, etc., can produce 5G You can expect to be accelerated by realization. Furthermore, in the agricultural and construction industries where the aging process is progressing, there are cases where the remote control of construction machinery has already been successful, and it is said that the way of working may change in the future.
The spread of 5G will dramatically improve the convenience of our lives and increase corporate productivity.

Are there any disadvantages that 5G brings? First of all, if there are more opportunities to connect to the Internet than now, it is expected that the security risk will increase. The more IoT plays an important role in society, the more likely it will suffer catastrophic attacks and catastrophic damage such as infrastructure outages.
In addition, in order for consumers to benefit from 5G, they must purchase new 5G-compatible devices and IoT-related devices. One of the disadvantages is that you have to buy a new smartphone, home appliance, and car.
It is still uncertain whether 5G will start smoothly. There is no possibility that service-in will be delayed more than expected and it will take time to spread.
When will next-generation communication technology 5G be put to practical use in Japan?
Initially, 5G had been commercial service provides start and eyes to the prospect 2020. However, recently there is a movement that puts that time ahead. In Japan, demonstration experiments are being carried out in stages, mainly for major carriers. It is said that 5G compatible smartphones will be released in 2019.
Although 5G is still a problem for diffusion, if it is put to practical use, it can be expected to improve corporate productivity and convenience of life. In a society where 5G has become widespread, it is said that smartphones may no longer be needed. This is because even if an individual does not have an advanced information terminal, it is possible to easily put in and out the necessary information as long as there are terminals that can authenticate the individual. They are also connected to AI and take care of troublesome operations. The future with 5G is getting closer.
