A story is rocking the world of communications today. You won’t have heard about it in our tiny corner of the world. It has nothing to do with cyber misdemeanors of our police or Bibi’s plea. Instead, it is a tail of arrogance and stupidity. Simply put, the roll out of 5G in the USA has been stopped in the vicinity of airports because the cellular signal for 5G towers can seriously affect the flight systems on modern planes like the Boing 777.
There is anger and recrimination flying around. In a video of a CNN interview of Tim Clark, the President of Emirate Airlines, described the rollout thus, “I need to be as candid as I normally am, and say this is one of the most delinquent, utterly irresponsible issue subjects, call it what you like, I’ve seen in my aviation career”. In fact, 7 airlines, including Emirates, have halted flights to the US until this problem is fixed. So what is the problem?
Modern commercial aircraft rely on an instrument known as a “Radio Altimeter” to know their height above ground on their landing approach. It works by sending a radar pulse using a carrier frequency of 4.2 -4.4 GHz. Basically, by sending a pulse and measuring the time taken to return, the aircraft can accurately know its height. This is really a radar pointing downwards.
