LPWA(Low Power Wide Area)というワードをよく耳にするようになりました。これは文字通り、「低消費電力での通信」を意味しています。このようなワードが流行るようになった要因は、これまた耳障りなぐらい流行っているIoT(Internet of Thing)の影響です。

 I often heard the word LPWA (Low Power Wide Area). This literally means “communication with low power consumption”. The reason why such a word became popular is the influence of IoT (Internet Of Thing) which is becoming more and more popular.


 As the basic configuration of IoT, there are end devices such as sensors, and they are transmitted to the gateway and server via communication modules attached to them. In this system, you can not change the battery of the end device every time. If I do that, I do not think anyone would use it, like a smart watch …. Therefore, low power consumption is an indispensable item in IoT! That is why the idea of ​​LPWA is prevalent. That was the introduction of LPWA.
