As I understand, it is prohibitively hard to make constant signal with high enough power, so SL will not work. So usually made trick - EW find when sync should be, and emit short high energy impulses, so snr become too low to receive sync part, and transmission effectively blocked. Spacex implemented new encoding, where sync is in random place in time-frequency, so now EW could emit, and this will lead to speed degradation, but not to full blocking.
