Introducing two communication technologies that are greatly involved in IoT
According to the Ministry of Internal Affairs and Communications’ White Paper on Information and Communication in the First Year of Reiwa, it is predicted that about 45 billion IoT devices will be connected to the Internet in the 2020s, and the amount of data communication will double.
Next-generation communication technologies called “5G” and “LPWA” are currently attracting attention in order to respond to future increases in communication volume and diversifying communication needs.
Communication Technology ① 5G
5G is a communication technology that realizes “high speed and large capacity,” “multiple simultaneous connections,” and “low latency .”
In the future, as IoT advances further, the processing of huge amounts of communication data will be required. With existing communication methods such as 4G and LTE, it is not possible to connect all things to the Internet at the same time and perform smooth data processing without delay. It is said that the start of 5G will support the spread of IoT, and the utilization of huge amounts of data will dramatically change the way many industries and occupations should be.
★ Three features of 5G
- communication speeds up to 20 Gbps.
- Approximately 20 times faster than the current 4G, the speed at which you can download a 2-hour movie in 15 seconds.
Multiple simultaneous connections
- The number of connected devices is 1 million units / km2.
- Approximately 10,000 terminals, which is about 10 times that of 4G, can be connected to the Internet at the same time.
- The delay is about 1 millisecond, which is about 1/10 of LTE. -You can operate and control things in remote areas in real-time without worrying about time lag.
Communication Technology ② LPWA
LPWA (Low Power Wide Area) is a communication technology characterized by “power saving,” “wide area,” and “low cost .” Although the communication speed is low, it is expected to be a communication technology that is compatible with IoT.
★ Three features of LPWA
① Power saving
-It is a general battery and has power-saving enough to operate for several years to several decades.
② Wide range
・ It has a wide area where communication of several kilometers to several tens of kilometers is possible.
③ Low cost
The connection cost is low and it can be operated at a low price.
5G is a new communication standard that replaces 4G and is scheduled to be put into practical use and commercialization in Japan from 2020. After the introduction of 5G, it is expected that technologies utilizing IoT will spread rapidly.
Understanding and using communication standards and technologies such as 5G and LPWA, which support IoT technology, will lead to the provision of new services and product value.
