Is that Upper or Lower Sideband?
Almost every communication in the world that is SSB uses upper sideband.
The notable exceptions are hams which use both (the practice is LSB
below 9mHz, USB above), BUT only 5mHz (which is USB) is regulated by law,
and over 50mHz both are routinely used.
The other exception is analog broadcast TV video. Analog TV audio is (was?)
FM except for France which used AM.
