Chipmaker Dialog seeks to make Bluetooth coronavirus apps more accurate
Dialog introduced software to improve the accuracy of wristbands and other Bluetooth-based devices being used for contact tracing. Chipmaker Dialog Semiconductor Plc on Monday introduced software to improve the accuracy of wristbands and other Bluetooth-based devices businesses are adopting to enforce social distancing and help trace those who were in contact with people who test positive for coronavirus infection. Several companies including Ford Motor Co are beginning to have workers put on smartwatches, lanyards or devices that are outfitted with technology aimed at preventing further outbreaks of the novel coronavirus. Dialog said its new “wireless ranging” code would attach special tones to signals and that its algorithms could process the new information to get a more accurate distance reading. The new software works with Dialog’s DA1469x family of Bluetooth low-energy chips, which is already installed in tens of millions of devices globally, mostly wearables such as smartwatches and fitness trackers.
