> For network operators, it raises a different question: could the infrastructure that already generates subscriber revenue also generate a second, sensing-based revenue stream?
Are there people who experience positive emotions in reaction to sentences like these? I just… even in my days when I thought social good came from states/organizations downward rather than from humans upward… even then, when I thought a God’s-eye view was achievable, that more and better measurable data were the way to get there, and that the main barrier to effective social regulation was poor legibility… I feel like even then this would ring craven and avaricious to me.
Oops, yep. Typing fast and thinking sloppily. I had in mind something closer to “exploitative” or “opportunistic.” Maybe it was my cravin’ for dinner speaking…
Someone presented a passive radar system using an RTLSDR receiving TV broadcasts reflected off of nearby planes at a 2017 GNURadio conference. If amateurs can do it, you can bet the military has already designed, built, tested, deployed, and retired a similar system.
This isn't exactly a new subject, the same concept powered the first radar guided missiles in the 1940s (enemy is illuminated by a ground or airborne radar, missile tracks the reflection).
I'm fairly certain I've already read an article in an IEEE magazine talking about this topic (passive radar via cell towers) a few years ago.

Craven?

This is not new as the article claims: Passive radars using FM broadcast and 2G GSM were used in the 1990s Yugoslav war.
