From the report, you’d seem to be totally on point.
To ascertain the probability of making calls inside an aircraft from differentaltitudes, a reconstructed flight using a King Air 350 over the said area andduring the same time when the signal “hit” happened was carried out shortlyafter the disappearance of MH370. The flight was conducted from an altitudeof 24,000 ft with step descents every 4,000 ft until 8,000 ft. The next descentwas to 5,000 ft but at 1,000 ft interval. An expert from a Telco service providerconducted the test using three different brands of phone and relatedequipment that were carried on board the King Air 350. Test call will beautomatically answered by the server in the event of connectivity. In summary, during the tests, it was found that it was difficult to maintainsuccessful call connectivity above 8,000 ft. However, one brand of phonewas able to make a call at 20,000 ft. Only one cell phone service providerrecorded the highest call attempts using their 3G network above 8,000 ft.Two service providers could only provide connection below 8,000 ft.
Earlier in the report the altitude was estimated to be between 24,000’ and 47,000’ so no cell would have worked.
