indoor GPS
The term “indoor GPS” is completely inaccurate. It really should say “indoor positioning”
The term “indoor GPS” is completely inaccurate. It really should say “indoor positioning”. There are two similar projects going on regarding indoor positioning: One of them uses angle of arrival (AOA) for calculation whereas the other uses WiFi positioning.
The Angle of Arrival concept was demonstrated at CommunicaAsia at Singapore Expo. It utilizes UWB (ultra-wideband) localization which can provide accuracy of up to 10cm.
The other indoor positioning experiment is being done by Nokia at a shopping center in Helsinki where they rely on triangulation using WiFi signals on their fancy Nokia S60 phones. The phone needs to run an application that can show where you are on the mall directory map.
