Still as the LightSquared issue has shown, as well as issues with GPS jammers used by truckers at airports (avoiding company monitoring) show that under the right conditions the systems can be degraded. The other issue is the Cellular system is not really meant for a random user to light up dozens of Cells from 30,000 feet -- Newer aircraft are certified to much more stringent standards than 1960′s aircraft — Boeing typically requires an OEM of avionics to show significant test margin above 400V/M for susceptibility on a critical system for a new design.
