First off, I don't have a great understanding about the physics behind radio frequency technologies. I'm working on a paper evaluating if LoRa infrastructure can help developing communities for a class in university. On the first few pages, I give an overview of how LoRa works and why it performs better in certain use-cases compared to other technologies like WiFi and LTE. As a part of that I want to give a quick overview of the basics of the physics behind it. The audience for the paper isn't very technical so a simplified explanation is probably enough. To my understanding, there is a correlation between Range, Power and Bandwidth (I got that from this video). For example, if one wants to increase the range of their transmission they'd have the option to increase the power or decrease the bandwidth (as LoRa does). I'm sure this is an oversimplification of the indirect proportionality between these aspects and I'm there are other aspects that play a big role when talking about RF range like antenna height, size and the wavelength. But I'd rather ignore these other aspects in my paper because it's far from the focus of the main thesis.

My problem: I can't find any respected sources to confirm this simplified explanation (probably because it's oversimplified), but the class expects me to use some springer handbook or other university grade source to confirm this.

My goal: Have a few sentences (confirmed by a good source) that explain the correlations between these aspects, so the reader has a basic understanding and will understand my comparison of LoRa to WiFi and LTE, showing the tradeoffs LoRa makes to increase range and keep the power requirements low.
