Sub 1GHz or other connectivity

For a new IoT proof-of-concept (PoC) I shortly start I need to measure some parameters like e.g. temperature in a building environment (building can be broad interpreted: an office building, a hospital, etc.). After some investigation I think an option would be using Sub 1GHz for connectivity.

My questions:

- Would indeed Sub 1GHz be a viable option for these kinds of use cases?

- Or, are there better alternatives?

- For our PoC what devkits/components (a few edge device kits + a gateway device to connect the edge devices to the Internet/CLoud), as a result of my 2 previous questions, can we best use?

Thanks.

There's a very nice IoT kit based on ST Sub 1GHz SPIRIT radio that may well suit your needs: look at

 evaluation board. It's a coin-cell battery operated wireless sensor with MEMS accelerometer, temperature sensor and humidity sensor. You'd use a few of these boards as 'edge devices' and

 as a gateway.
