Rajesh Mehrotra, an erstwhile functionary of the Space Services Department of ITU Headquarters in Geneva, Switzerland, argues that the C-band beyond 3600 MHz and Ka-band beyond 27.5 GHz are NOT as per the collective decision made in the ITU's WRC-15 conference for identification of 5G/IMT bands for India
Distance on a phone on an actual phone line, 5g is how we live our lives, right? we're streaming, using social media, the holograms at basketball games. this is the future. you're a pilot. how does this technology affect airplanes? >> yeah, you know, i want 5g, too, but it's important to know that this part of the 5g frequency band, the c-band right next door to the part of the spectrum used by a crucial device on airliners, the radar altimeter, it's designed to tell an aircraft how close it is to the ground when it's getting really close to the ground in really bad weather in particular. you ...
Disrupt radar altimeters -- instruments that bounce a radio d beam at the ground to give a hyperaccurate reading of height. pilots call the system essential when they need it most, in poor weather when it's hard to see the runway. >> this one instrument if it gets bad data, sends it to a collection of other systems, flight krols, auto notless, stick shake, i could go on and on. each of those, if they get bad information in, they are going to do bad things. >> reporter: in this simulator of a regional airliner, i saw what happened when a radar al tim ter fails. automatic warnings could stop and...
The airline ceos have been saying for months that they're worried about the possibility that the new 5g cell service will interfere with critical radio altimeters or radar altimeters that are on board planes. that technology is used when a pilot is coming into an airport that is socked in. you have bad weather, you use the altimeter to determine your exact or precise altitude. the concern is that 5g ground stations, so not your phone, not the phone, the ground station itself may interfere with that technology in the cockpit. this has been an ongoing back and forth between the faa, where the sh...
Around this long? it is a valid question. you have the faa and fcc going back and forth between the two, each sort of advancing their own position. there have been joint working committees. there have been commissions. there's been all kinds of stuff done in the past year to try to resolve it, and it never got resolved. the end of the day, joe, as you eluded to, when the faa says it is a safety issue, it is very hard for anybody to counter that. when the airlines say, we're just not going to fly, it is very hard for anyone to counter that. so at the end of the day, the cell phone companies, in...
