If you want to get really spicy, you can use two antennas and an SDR to compute angle of arrival using nothing but a BLE advertisement's data . This is different from BLE AoA as it doesn't require a cooperative transmitter.
- alias_neo 3y agoIf you want to get really, really spicy, use three devices/antennas and you can roughly track in three-dimensional space.
- milkshakes 3y agothere are wifi setups that allow you to do this already.
- worthless-trash 3y agoI would like to subscribe to this API.
- greggsy 3y agoWouldn’t three dimensional tracking need four antennas?
- rsaxvc 3y agoThree appropriately spaced antennas will give you azimuth and elevation of a ray to the transmitter, but not distance. But using two of the above in different, known locations would allow you to compute the intersection to a 3D location.
