Snooping on cell phone texting

So we have night vision goggles to see in the dark… Infrared to see heat… Why aren’t there special glasses to see wireless communication?! Do you ever wonder what wireless signals look like? I mean if a single unencrypted piece of data is floating around is it 0’s and 1’s in the air? I get that sound travels as vibrations that our ears interpret into words we understand but how does wireless data work? If stuff is flying around why can’t we make a machine to see it flying around? How about neon colors for different channels of data? People would no longer need acid if we had these kind of devices!

This is the kind of stuff I think about while driving to and from work.
