The 3 main network technologies for IoT Connectivity are:
1.Standard Wireless Access – WiFi, 2G, 3G and standard LTE.
2.Private Long Range – LoRA based platform, Zigbee, and SigFox.
3.Mobile IoT Technologies – LTE-M, NB-IoT, and EC-GSM-IoT
There is no doubt that IoT is driving a lot of changes in connectivity (among many other infrastructure technologies). The rule that connected devices impose over networking technologies is not the same as in our mobile phones. Today we are in the middle of a technology change that we may not yet realize. As any transition, there are a lot of standard and legacy technologies fighting. The winner would be the connectivity of choice by the nearly 50 Billion devices.
