Abstract
A wireless communication device transmits a hierarchically modulated reverse link (RL) WWAN signal comprising a lower modulation order component corresponding to first service level data and a higher modulation order component corresponding to second service level data. An interface node receives and demodulates the hierarchical modulated signal to recover second service level data. The interface node sends second service level data to a recipient.
