Even if you're not a frequent flyer, you've probably heard that the Federal Aviation Administration (FAA) and numerous airlines are claiming that AT&T and Verizon Wireless's recently approved C-Band 5G will dangerously interfere with airplanes take offs and landings.

Will this new 5G be dangerous? Can a 5G call knock a plane out of the sky? Here's what we know:

What kind of 5G is potentially dangerous?

There are three basic kinds of 5G: 

• Millimeter wave (mmWave): Very fast, up to 1 Gigabit per second (Gbps), but has an extremely short range.
• Midband: Has speeds around 100 Megabit per second (Mbps) and 4G range.
• Lowband: Only comes with speeds around 20Mbps, but it has a range of dozens of miles. 

What has the FAA and the airlines worried is a new midband variation: C-Band 5G.

The chunk of spectrum known as C-Band lies between 3.7 GHz and 4.2 GHz and it's capable of speeds in the 200-800Mbps range. In the past, it was used for satellite video providers and satellite phone services. AT&T and Verizon bought up the bulk of this spectrum for a combined$68 billion. You don't spend that kind of money unless you plan on using it. 

Quick Note: There's no evidence behind the rumors that other kinds of 5G cause health problems.

What's the problem with C-Band 5G and airplanes?

The FAA has warned airlines that these signals could interfere with some altimeters that pilots use to land in conditions with low visibility. 

According to a report from the Radio Technical Commission for Aeronautics (RTCA) -- a technical non-profit used by government and industry regulatory authorities -- "this frequency band may introduce harmful radio frequency (RF) interference to radar altimeters currently operating in the globally-allocated 4.2
