434 Mhz RDT

Post by Stew »

Hi all.

Just stumbled across this today. What is the benefit of 433Mhz against 2.4ghz?
Seems a handy little device but does anyone know much about it?

The only advantage I know of 433MHz vs 2.4GHz is that the lower the frequency, the greater the range for the same power output and better it penetrates buildings, walls, trees etc. It's obviously a lower power device, maybe easier to achieve the low power at 433MHz?

The claimed up to 2750 metre range might be a wet dream.
