European governments are seeking assistance worldwide in blocking an attempt by terrestrial-wireless broadband interests to use a slice of radio spectrum now reserved for radar Earth observation satellites, particularly those in development in Europe and Canada. In a new version of a similar dispute with satellite telecommunications services operating in a different portion of the C-band spectrum, the terrestrial-broadband promoters - Cisco Systems, Intel, Qualcomm and Broadcom among them - say the frequencies in question can be shared with little or no harm to radar satellites' effectiveness. In a mid-January submission to the 48-nation European Conference of Postal and Telecommunications Administrations (CEPT), the broadband companies say even studies that show radar Earth observation signals at their most fragile end up concluding that Wi-Fi use and radar satellite imagery can coexist without interference.
