There is no single answer here? The infrastructure required will vary based on
the physical terrain, power levels etc.

Why did it fail Bert?
The technology worked quite well, and demonstrates that there are many ways to
design a modern TV distribution infrastructure.
To answer my question, Media Flo failed because of the business model.
Consumers did not find a compelling need to pay for another bundle of TV
channels that duplicated what they already were paying for via their MVPD
service.
Contrast this with TV Everywhere, which provides mobile access to the channels
you are already paying for.
The real issue in play is whether there is a compelling need for TV
broadcasting at all, and if the answer is yes, what physical transmission
infrastructure is most likely to get people to support the service.
Pervasive WiFi coverage could render this discussion irrelevant.
