Sort of. Rf line of sight os not the same as visual line of sight. The horizon is a different effective distance based on frequency to some extent due to refraction.

Higher tower also significantly extends the apparent horizon and will allow it to get past some obstacles.

@matrix

@freemo @matrix Yeah, that's true.
The frequency can also play a big role.
LTE B71 (600 MHz) will act and propagate differently than say LTE B41 (2.5 GHz).

@sjw

Yup, low frequencies will bend around smaller objects like buildings like they arent even there, higher frequencies are blocked trivially by even thin metal obstacles, etc.

Then of course if you get into 10Mhz and below you start getting ionosphere bounce and can go 10,000 km without batting an eye in the right conditions.

@matrix

@freemo @matrix Bending is one thing but you also have to think about how well the signal can penetrate. Especially for use indoors or in dense city settings. E.g. VHF vs. UHF.

@sjw

For sure,, but its also not a simple measure.. higher frequencies have higher penetration depths through nonconductive material like concrete. However they tend to be less penetrating through conductive material like wet ground or metal.

@matrix

@freemo @matrix Yep yep. Radio can be complicated. Hell, planning out a large scale Wi-Fi network is hard enough. Cell network has gotta be 10x harder.

Fer shure
