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.

Abstract: In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: an ultra-wideband (UWB) communication unit configured to set up a UWB communication channel with a first external communication device; a further communication unit configured to set up a further communication channel with a second external communication device; an antenna configured to be selectively used by the UWB communication unit and the further communication unit; wherein the UWB communication unit is operatively coupled to the further communication unit, and wherein the further communication unit is configured to grant the UWB communication unit access to said antenna in response to receiving a request from the UWB communication unit. This aspect represents a solution to the problem of how to facilitate avoiding that UWB ranging rounds fail in a co-existence system.
