Economies could reach a new level of efficiency if utilities (electricity, gas and water, etc.) are connected to the internet. To connect the utilities to the internet requires a technology that meets a certain price point on the device-end. LTE connectivity can cost around $50 on the device-end as it requires 2 antennas and two receiver chains. 2G can cost around $10 but, the technology can spiral power consumption levels of the device out of control.
I feel that there needs to be a benchmark that is required by a low-power-wide-area connectivity technology to meet in-order for the technology to be beneficial in the IoT environment. For instance, less than $5 might be the ideal price-point for connecting the end device and 5 to 10 years battery life should be expected. I wonder if NB-IoT is the technology that delivers close to these requirements.
