The IOT technology:
https://www.youtube.com/watch?v=6WMzRrmMjQU


My initial impression:
It uses proprietary devices and proprietary standards. Needs to lay down its own LoraWAN network for the TBS-200 sensors to connect. Uses its own proprietary long range radio networks. Uses apps for mobile phones. Google Play has apparently rejected the app. Only iOS is available. That all adds up to the high implementation costs of RM115 million.

Should use:
Internet which is already available and wifi hotspots for long range communication. Also, should build mobile phone browser apps - to avoid the hassle of getting Google and Apple's approval.
