Due to the much lower frequency range of C-band, the margin for weather degradation is often only 1 decibel (dB), but in Ku-band it can be 6 to 10 dB in subtropical and tropical regions. Power losses of 10 decibel in Ku-Band equate to the need of a tenfold power increase or an antenna diameter of 3.80 m in tropical regions instead of 1.20 m needed in drier regions — for the same service availability! The 2way2sat services offered by atrexx are based on the iDirect iNFINITI platform over the Intelsat 10-02 satellite. Intelsat 10-02 boasts very strong C-Band coverage over all of Europe, the entire African Continent and the Middle East and comprises 45 C-Band transponders. The offering fills a gap that atrexx had previously been identified for iDirect-based services in C-band over Africa.

atrexx Not Fading Away In Africa
atrexx Ltd. & Co. KG is offering more widespread 2way2sat services in C-band to tropical regions, especially to Africa, where rain attenuation often presents a problem. The company is responding to many inquiries that they have received from users who currently find themselves underserved by C-band services.
"Rain fade is still a considerable issue for users of Ku-band satellite services in areas where wet weather is extremely common, causing disruption of services that cannot be delivered through any other means", commented Jean-Claude Bisenius, Managing Director of atrexx. "This can cause problems for important public services that rely on satellite-based services as an alternative to terrestrial that cannot reach certain areas or is too expensive to roll-out."
