OK, dumb question; of course you do. You have a smartphone with GPS that tells you (and probably way more people than you might be comfortable with) where you are. But, if you turn GPS off or were inside a building that blocked the GPS signal, then would you know? We’re talking about location services here, and there are two essential questions, each with a different answer: The difference boils down to this: given some location service, the first scenario has that service figuring out where an asset is. The second scenario has that service helping the asset to figure out where it is. There are two new Bluetooth capabilities that make this possible: angle of arrival (AoA) and angle of departure (AoD). We’re going to sort through those today. I came to all of this through a conversation with Silicon Labs. They announced both WiFi and Bluetooth improvements in their software that runs on their Gecko family. And the big news on the Bluetooth side is this new location-finding capability. So let’s work through these two functions to see how they work. And I’ll confess… I’m not an RF specialist, so some of this wasn’t obvious to me without some studying. Hopefully that will help for ...
