Abstract
An apparatus may include a memory to store a first radio signal strength indicator (RSSI) data set comprising first data entries for RSSI detected from a multiplicity of transmission sources by a first wireless device of a first device type, and to store a second RSSI data set comprising second data entries for RSSI detected from the multiplicity of transmission sources by a second wireless device of a second device type; and a cross-device radio calibration engine to receive the first RSSI data set and second RSSI data set and generate a cross-calibrated RSSI function comprising a function that reduces differences between the first RSSI data set and the second RSSI data set. Other embodiments are disclosed and claimed.
Claims28
An apparatus, comprising:
- a memory to store a first radio signal strength indicator (RSSI) data set comprising first data entries for RSSI detected from a multiplicity of transmission sources by a first wireless device of a first device type, and to store a second RSSI data set comprising second data entries for RSSI detected from the multiplicity of transmission sources by a second wireless device of a second device type;
- and
- a cross-device radio calibration engine to receive the first RSSI data set and second RSSI data set and generate a cross-calibrated RSSI function comprising a function that reduces differences between the first RSSI data set and the second RSSI data set.
At least one non-transitory computer-readable storage medium comprising instructions that, when executed, cause a system to:
- receive a first radio signal strength indicator (RSSI) data set comprising data detected from a multiplicity of transmission sources by a first wireless device of a first device type;
- receive a second RSSI data set comprising data detected from the multiplicity of transmission sources by a second wireless device of a second device type;
- and
- generate a cross-calibrated RSSI function comprising a function that reduces differences between the first RSSI data set and the second RSSI data set.
A method, comprising:
- receiving a first radio signal strength indicator (RSSI) data set comprising data detected at a first instance from a multiplicity of transmission sources by a first wireless device of a first device type;
- receiving a second RSSI data set comprising data detected at a second instance from the multiplicity of transmission sources by a second wireless device of a second device type;
- and
- generating a cross-calibrated RSSI function comprising a function that reduces differences between the first RSSI data set and the second RSSI data set.
A system, comprising:
- an interface to receive received signal strength indicator (RSSI) data for a first wireless device of a first device type;
- and
- a location engine to receive a cross-calibrated RSSI function for the first device type, the cross-calibrated RSSI function comprising a function that reduces differences between a respective first RSSI data set detected from a multiplicity of transmitting devices by the first wireless device and a second RSSI data set detected from the multiplicity of transmitting devices by a second wireless device of a second device type;
- and to determine device location of the first wireless device based upon the received RSSI data and received cross-calibrated RSSI function.
