- Z-Wave operates at 868MHz (in EU) and has up to ~100-meter range
- LoRa operates at 868MHz (in EU) and has up to ~15 km range
My knowledge says that the lower the frequency = the higher the range/penetrability.
However, both these technologies operate at the same frequency, so how come LoRa is able to achieve such a long-distance?
Furthermore, I'm a bit confused, as to how power consumption plays a role in the above situation. I'm assuming a high-powered signal means that the waves themselves have a higher amplitude, thus making it harder for other signals to interfere.
With that assumption, does that mean that LoRa uses a lot of power to reach such a long-distance?
