Some Australian pilots may be aware of the 5G interference thread with a link to this report
https://www.rtca.org/wp-content/uplo...ed_changes.pdf which is rather heavy going, but contains a rather worrying Executive Summary. In short, the tests seem to reveal potential interference between the new US 5G bands and the nearly-adjacent Radio Altimetry band (4.2-4.4GHz).
Does anyone know if the airlines were involved in any representation to ACMA prior to the allocation of the new 5G mobile phone spectrum? Don't get me wrong, I'm not in the anti-5G lobby. But I do like my Radio Altimeter to be reliable, as it's especially useful in the final phases of flight, that bit near the ground. Just wondering if anyone's been checking out the situation what with all the other distractions.
