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.
Claims20
A system, comprising:
- a plurality of ultra-wideband (UWB) anchors configured to broadcast UWB timing data in a plurality of data packets, wherein each data packet is associated with a preamble code;
- and
- a device, including:
- a first radio controller configured to communicate with the plurality of UWB anchors using a first protocol,
- a pseudo random number generator configured to generate a pseudo random output value based on an input data value;
- and
- a processor configured to:
- provide the input data value to the pseudo random number generator to cause the pseudo random number generator to output the pseudo random output value;
- determine, using the pseudo random output value, a preamble code;
- process a data packet received using the first radio controller and from a first UWB anchor in the plurality of UWB anchors using the preamble code to generate a processed data packet;
- and
- determine a location of the device using the processed data packet.
