Hi folks, first post. I’m no expert on RF so I’ve been doing some reading to try to get my head around stuff.
Is there a difference between the maximum allowable transmission power for an emitter in the UK versus the max transmission power allowed in the US?
Looking at the tech-specs for the default TTN gateway linked to from this site, I noticed that the 868 Mhz variant (EUR) has a maximum TX power of 14 dBm or 25 mW and the 902-928 Mhz variant (US) has a maximum TX power of 27 dBm or 501 mW. That’s some jump in power output!
If I am correct, does this have a significant effect on signal penetration in urban areas in the UK vs when used in the US?
