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.

Just a thought, in my own experience my first investments, which happened to be just after college, were poor choices. The way I see it is that if you make the poor choices earlier with less money you will be better educated and equipped to make better choices sooner. I don't think there is anything magical that turns on after you're done with college that makes you better at investing money.
