Context: <response>: Frequencies for COMPASS dey allocated for four bands: E1, E2, E5B, and E6 and dem dey overlap with Galileo. The fact say dem dey overlap fit dey good for receiver design, but e fit bring ish of inter-system interference, especially for E1 and E2 bands, wey dem allocate for Galileo's publicly regulated service. But based on International Telecommunication Union (ITU) policies, the first nation wey start to dey broadcast for specific frequency go get priority for that frequency, and any other users go need to get permission before dem fit use that frequency, and make sure say their broadcasts no dey interfere with the original nation's broadcasts. E be like say Chinese COMPASS satellites go start to dey transmit for E1, E2, E5B, and E6 bands before Europe's Galileo satellites and so dem get primary rights to these frequency ranges.
