On #NationalRadioDay, we're also celebrating some of the technology behind radios because, without it, this would happen. 👇

Wi-Fi fills our world with radio waves. Now researchers can exploit ambient signals to track individuals in their own homes.  https://www.technologyreview.com/s/612375/using-wi-fi-to-see-behind-closed-doors-is-easier-than-anyone-thought/?utm_medium=tr_social&utm_campaign=site_visitor.unpaid.engagement&utm_source=Twitter#Echobox=1566310749 

Who gets to send radio waves in space?  https://www.technologyreview.com/s/613751/spectrum-wars-satellite-communication/?utm_medium=tr_social&utm_campaign=site_visitor.unpaid.engagement&utm_source=Twitter#Echobox=1566310811
