With the deployment of 5G, mobile operators have taken up a number of different frequency bands, including C-band spectrum, which has been used by satellites for over five decades. However, as we should argue, C-band is not the correct band to support the key performance indicators (KPIs) that are promised by 5G.

5G is being billed as a revolutionary force that will transform the way we live and work, which warrants taking C-band spectrum away from satellite-based applications to speed up service availability. But the real story is that many things on the road to 5G remain uncertain.

In light of the roll-out of 5G in Hong Kong, AsiaSat has accelerated efforts to provide the necessary protection for its C-band TT&C (Telemetry, Tracking and Control) and TVRO antennas against potential interference from 5G deployment, to ensure the continuity of satellite operation and uninterrupted service to customers.
With the imminent arrival of 5G, AsiaSat’s CEO Roger Tong talked about the various mitigation measures including the company’s new series of bandpass filters to protect customers’ C-band services against out-of-band interfering signals from nearby 5G base stations.
Standard C-band downlink frequencies, 3.7-4.2 GHz, are globally identified and used today, with the extended C-band 3.4-3.7 GHz, to deliver a wide range of critical satellite services, which in many cases cannot be reliably provided by other means.
