Moving back to the LOCAL LOOP question...
Have ICASA defined what they view as the wireless loop loop, taking into consideration that there is no fixed point of connect on the customer's side?
Yes, they did... from the article:
“Local Loop” means all physical media, including electrical, optical and radio frequency, used as the electronic communications facilities for the connection of an end-user or end-site to an access network aggregation point on the electronic communications network.
"Local" is being used in context of "Local to the user", not "Local to a fixed location".
