Abstract
An ultra wide band, UWB, ranging device is disclosed comprising: an input for receiving data directly from a sensor hub, and a radio configured for UWB communication; wherein the UWB device is configured to: commence a ranging process comprising at least one of a repeated range determination, and a repeated angle of arrival determination; receive sensor data from the sensor hub; process the data, and modify the ranging process in dependence on the data. Personal communication devices disclosing such UWB ranging devices are also disclosed as are associated methods.
Claims15
An ultra wideband (UWB) ranging device comprising a UWB integrated circuit (IC), wherein the UWB IC comprises:
- an interface connected to an applications processor;
- an input for receiving sensor data directly from a sensor hub, and
- a radio configured for UWB communication;
- wherein the UWB ranging device is configured to:
- commence a ranging process comprising at least one of a repeated range determination, and a repeated angle of arrival determination independent of operation of the applications processor;
- receive sensor data directly from the sensor hub;
- process the received sensor data, and
- modify the ranging process in dependence on the processed sensor data.
A method of operating an ultra wideband (UWB) ranging device comprising a UWB integrated circuit (IC), the method comprising:
- interfacing the UWB ranging device with an applications processor;
- commencing a ranging process using the UWB ranging device, the ranging process comprising at least one of a repeated range determination and a repeated angle of arrival determination independent of operation of the applications processor;
- receiving, by the UWB ranging device, sensor data directly from a sensor hub;
- processing, by the UWB ranging device, the received sensor data;
- and
- modifying the ranging process based on the processed sensor data.
