The C-Band Alliance was formed in October last year, along with Intelsat, SES and Telesat. They proposed handling the clearance of up to 200 MHz spectrum in the so-called C band for use by 5G mobile services. The satellite operators said they would voluntarily release part of the spectrum in the 3.7-4.2 GHz range, in exchange for compensation from mobile operators for the costs of clearing the frequencies.
