i have a few ideas for a semester-long radio project, but at this point i’m leaning toward doing something with the subway wi-fi infrastructure.
by digging around there, i learned that these freaky dangling things i’ve been seeing more and more of are actually antennae. they make up something called a distributed antenna system, and my understanding is that they’re relatively new infrastructural inventions. i think they work like relays to bounce messages to each other in spaces where it’d otherwise be difficult to get a radio/wi-fi signal.
i downloaded some fcc documents about this stuff: ownership, regulations, etc. i’d be curious to get the fcc IDs of some of the devices.
this is the land of a thousand rabbit holes, dangerous territory for me. more updates as i learn more.
