Quite so. This is why infrastructure providers are planning to use lamp posts, public buildings and the like. In rural areas where no street lighting exists this becomes a problem. However, many domestic WiFi routers come with dual WiFi SSIDs and separate VLANs to allow 3rd parties to use your WAP as a WiFi hot-spot, as long as they already have a user account with the same ISP, or are willing to register and pay exorbitant fees (at least in the UK) for a few hours usage. I can see a possibility for this hot-spot functionality extending to offer domestic 5G aerial repeaters, but in the country side with miles of 'no-spots' this is not going to offer much geographic cover anyway. -- Regards, Mick
