Philips and Microsoft work together to indoor-positioning business. Philips is embracing Bluetooth in addition to the visible light communication.
In two moves to jump-start the stalled indoor-positioning business, Philips Lighting said it has rounded up IT companies including Microsoft and SAP to develop compelling data-linked uses that might actually attract customers. And in an underlying wireless technology change, Philips quietly revealed that it is now embracing radio-based Bluetooth in addition to the visible light communication (VLC) that it has long preferred.
Indoor positioning — also known as location-based services — transmits signals to smartphones in order to guide and engage people around buildings such as retail stores and offices. Lighting companies want to use ceiling luminaires to send the signals. Philips has persistently championed VLC, which embeds signals in the modulation of lightwaves emitted by LEDs. Other vendors such as Osram and startup Gooee prefer Bluetooth beacons that send signals from chips inside light fixtures.
