What do you use for data transmission, IoT or networking below 300 and 1-3km? [Copy link]

As the title says, in today's smart domestic market, I would like to ask everyone:

What do you use for data transmission, IoT or networking below 300 and 1-3km?

In the past, direct transmission was done using radios below 433MHz, and later higher frequencies were used for transmission. How do you choose communication and networking methods now?

For this distance, I think 433 is the most suitable for networking.
