5G is the 5th generation mobile communication system. Featuring “ultra-high-speed communication”, “ultra-low latency” and “multiple simultaneous connections”, it is expected to be used in all industries and industries.
Is 100 times faster than 4G?
The maximum communication speed of 5G is 20 Gbps, which is about 100 times faster than 4G (LTE). 4G takes 5 minutes to download a 2-hour movie, but 5G takes 3 seconds to finish.
Will be available in Japan from 2020
In April 2019, the Ministry of Internal Affairs and Communications allocated frequencies for 5G to four mobile phone companies. A test service will be launched in the fall of 2019, aiming to start full-scale service provision after the spring of 2020, each company is activating the movement of developing new products compatible with 5G.
IoT will accelerate with 5G
5G is expected to promote the IoT of society (connecting various things to the Internet) and is expected to have a great impact on all industries.
When is the expected start time
A group called 3GPP that standardizes mobile band communications plans to finalize detailed specifications by around October 2019. Generally, it is around spring 2020, and the detailed date and time of introduction will differ for each mobile carrier.
However, if one company starts 5G, it is highly possible that other companies will start as if they are competing, and there is a very high possibility that it will be earlier than expected.
What is the reason and reason for introducing 5G?
It can be said that the reason and the reason is that the communication speed is expected to improve due to the progress of IT technology, and the traffic of data information volume on the Internet is also increasing these days. Another reason is that communication standards that enable a large amount of information to be exchanged in real time are being demanded due to the spread and evolution of IoT devices and devices, as well as other technological advances.
About carriers introducing 5G
3 major mobile carriers, NTT Docomo, au, and SoftBank are all planning to introduce 5G. It is expected that other carriers will gradually expand.
At the moment, I don’t see any information on significant price increases, but considering the maintenance of equipment and infrastructure to support 5G, it may be possible to raise the basic charge, or consider a separate charge for 5G only.
