Can anyone explain what the key limits on bandwidth are when communicating from Mars? Is it just a matter of higher bandwidth requiring higher energy consumpti

  It's wireless transmission. Your bandwidth is a function of the frequency of your communication channel, and long-distance transmission generally uses low-frequency signals (and as a result, low speed). The one way to get around this is to use a multi-channel link, that is to say you communicate over several frequencies simultaneously. This is more difficult, both technically and because you must find unused frequencies.
