The communication speed is 100bps, and the wide -area network "SIGFOX" (Sigfox) using the 920MHz band that does not require a license will start in Japan.The Kyocera Communication System, a Kyocera subsidiary, has partnered with the Buddha SIGFOX and has been developed as the only network operator in Japan.We aim to area major cities by March 2018.
How to connect things to the Internet
SIGFOX(シグフォックス)は、フランスのSIGFOX社が展開するIoT専用の無線ネットワークです。2020年までに500億を超えるIoTデバイスの普及が予測されるなか、IoT普及のネックになるのが「How to connect things to the Internet」であると黒瀬 善仁氏（京セラコミュニケーションシステム 代表取締役社長）は言います。
In Japan, 3G and LTE networks that can communicate high -speed communication are being overlooked nationwide, but President Kurose points out that it is "expensive" to use it in IoT.In addition, IoT communication is said to be mostly the need for sending small data such as water level and temperature.Therefore, SIGFOX appeared as a network optimized for IoT communication.
One line is around 100 yen per year, can be communicated overseas
There are three characteristics of SIGFOX: low price, power saving, and long -distance transmission.The frequency band uses a 920MHz band that does not require a license, and the maximum transmission distance reaches several tens of kilometers.In terms of power saving, it is explained that the battery can be used for about 5 years, and regular charging is unnecessary and it is suitable for outdoor use.
According to President Kurose, "If the number of communications per day is two or less, one line will be available for around 100 yen per year."He explains that things that have not been connected to the network will be connected due to cost problems.The competitive IoT networks include NB-Iot and Lorawan.Regarding the advantages compared to them, President Kurose is developing the same network overseas.SIGFOX is operated in 24 countries around the world, mainly in Europe and North America, and will expand to 60 countries around the world by 2018.One of the IDs of SIGFOX, selling communication in Japan and overseas in the same way.
▲ Kyocera Communication System President and CEO Yoshihito Kurose, President Kurose, who announced his entry into SIGFOX, President Kurose, said, "In order to capture the movements around the body as data and accumulate in the whole society, it is in order to use it in the whole society.It is indispensable to collect big data at a low price. "(Correction) Initially, "I used the 960MHz band that does not require a license ~", but it was a 920MHz band correctly.We apologize for the correction.
