Just hope your not in/near one of the top 46 markets. Those folks will need a 3.8 filter first.... then a 4.0 filter later.
To some extent but not likely as strong as the towers. Also not sure what the phone transmitter frequencies are for 5g, there will be a tx/rx offset with tx likely farther down in the spectrum. I know a few people in the telecom business up here, none really seem to know what the channels will be... or aren't saying for some reason. Then the channels up here might be different from the US, although the phones here need to work in the US and US phones need to work in Canada, that might be something they are still working on.All your neighbors 5G phones will be interfering too though, right?
