PARIS — The C-Band Alliance of U.S. satellite operators has sent binding commitment letters to customers guaranteeing that the alliance will cover the costs of transitioning from the current 500-MHz of spectrum to 300 MHz following the sale of spectrum to 5G mobile network operators.

The costs to satellite C-band customers include adding filters to every one of their antennas to prevent interference from 5G broadcasts in the lower 200 MHz of the 3.7-4.2-GHz band that satellite operators now use.
