The technology required to transmit/receive microwave radio, carrying a multiplex of telephony and broadband to multiple customers, over a distance of 4Km is a huge step change from the wi-fi we are all accustomed to. The cost to the subscriber would be significant. The cost is I think higher than fibre optic cable. I’ve not been around the telephony industry for a considerable number of years, so no idea on current costs, but I think I’m not far away from the cost estimate. I look with interest for any input from current industry experts.
