You’re absolutely right Robert. As with any high-level look at a nuanced topic, the finer details will be missed. Within each of these groupings, the options can still vary greatly. As you mention, BLE (Bluetooth Low-Energy for those unfamiliar) is much lower energy but also has less range than WiFi.
Overall, it still holds true that each specific option represents a tradeoff between the power consumption, range, and bandwidth. To improve one you have to give up another to some degree.
With these posts, my intent is to provide a foundational understanding for those new to IoT. But I also don’t want to spread misinformation, so I really appreciate your response and hope you’ll let me know if ever I miss an important detail in these explanations.
