Fibire to the radio head...
Given the amount of potentially dark fibre required for OpenRAN this is going to be quite an interesting roll-out. The "rural" bit is particularly fascinating as I think that this technology really works for densification in cities where there already is a lot of fibre already installed and there is a big drive for capacity. A lot of the places where there are rural sites won't readily lend themselves to the CU, DU, RU model on the distance restrictions so I am not sure it will be as cost effective as they think it will.
