Chương 30: Sol Four, Antenna Father and Antenna Son

Tomcat sat on a chair as it began to attempt re-establishing communications with the United Space Station.

Normally, Kunlun Station would communicate with the United Space Station through radio transmissions via Ku, L, and C band designations. Among the bands was the Ku band designation which was in the frequency range of 12 to 18 GHz. It was a very mature band designation. Decades ago, the satellite dishes installed on many households' rooftops used the Ku band designation.

This frequency allowed very fast communication speeds, equivalent to 500 Mbps broadband. Mai Dong and Tang Yue usually used this frequency during their video communications.

The other L and C bands were used as backups. The L band's frequency ranged from 1-2GHz, a type of millimeter-wave. The C band's frequency ranged from 4-8GHz. Compared to the Ku band, more time had been poured into studying these two frequency bands. It was more mature technology which was why it was used as a backup.
