Did you read the essay he posted? It doesn't look like you need to understand the material at all to get the top mark.

Considering the standard when talking about this stuff is the smaller 'b' and that is approximately the bandwidth used by a single DTV station I would say Mb:s.

Hmm,

I'm pretty sure this is for home/office only at this point so no battery use. Also we still have 600mhz stations which should work for the uplink. I mean they are starting to use the 700mhz spectrum for cell phones - so I don't see why the 600s would be an issue. They could use the lower frequencies for downlink only.
