Abstract: A device includes a first radio controller configured to communicate using a first protocol, and a pseudo random number generator configured to generate a pseudo random output value based on an input data value. The device includes a processor configured to determine a preamble code based on an output of the pseudo random number generator, and process a data packet received using the first radio controller using the preamble code to generate a processed data packet.

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 execute a UWB ranging session with an external communication device; a further communication unit configured to set up a secure communication channel with the external communication device; a processing unit configured to carry out a transaction through the further communication unit in dependence on a result of the UWB ranging session; wherein the processing unit is further configured to wrap said transaction within the secure communication channel. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication device is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.
