Spacecraft re-entry

  1. Oct 31, 2012 #1
    I recently read about the communication blackout during a spacecraft re-entry.. The reason given was the high density plasma formed whose plasma frequency is such that the communication waves do not penetrate it. Why don't we use a higher frequency for communication which is sufficient to pass through the plasma?
