Output power router query

[CurlyWhirly]

I am new to routers so am curious as to some of the information that I can see in the homepage.

In my screenshot below is an entry for output power:




What I would like to know is what it actually tells you?
Does a higher rate mean a cleaner broadband signal or is it the output of the router itself?

Also I assume it is related to line noise as it has dB in the result
Finally what does the 'm' stand for?

Sorry for all the questions

It means that the router (or the line card) is using a higher power.
It does exactly what it says on the tin.

Also I assume it is related to line noise as it has dB in the result

Higher intensity of noise is going to need a higher power output to overcome it, so yes, sort of.

Finally what does the 'm' stand for?

Er, metres?
