The corollary of the claims for the DIDO technology is that if you have few users and few overlapping base stations (ie as in rural Australia) the technology will offer little gain over today's technologies. And to serve many users in a small areas is likely to need a large number of access points each with limited coverage area to limit the processing load.
The white paper does not go into any details that would answer the question: "If the are x users in an area of y square kilometres how many base stations wil be needed to deliver bandwidth of zMbps to each user, given the central processor's ability to handle the processing load involved?"
What it does say is: "You can think of the DIDO access points as a vast random array of antennas extending out from the DIDO data centre for miles, but instead of running long wires from the data centre to the antennas, DIDO uses the Internet to connect to each DIDO AP, allowing each DIDO AP to be placed anywhere there is an Internet connection, whether indoor or outdoor, much like a WiFi AP could be placed anywhere there is an Internet connection."
Which sounds remarkably like the topology of WiFi, or a cellular network with lots of picocells and femtocells. And the more bandwidth this technology can deliver the more backhaul will be needed.
I've no expectations that DIDO will make a Dodo of the NBN any time soon.
