Abstract
A position location method includes receiving, over a messaging link, a request from an access point of a position location system to perform a ranging operation between a first asset tag and a second asset tag. The method also includes transmitting, by the first asset tag, a first ranging pilot signal on a ranging link to enable the ranging operation between the first asset tag and the second asset tag. The method further includes receiving, by the first asset tag, a second ranging pilot signal on the ranging link from the second asset tag.
Claims24
A position location method, comprising:
- receiving, over a messaging link, a request from an access point of a position location system to perform a ranging operation between a first asset tag and a second asset tag of the position location system;
- transmitting, by the first asset tag, a first ranging pilot signal on a ranging link to enable the ranging operation between the first asset tag and the second asset tag;
- and
- receiving, by the first asset tag, a second ranging pilot signal on the ranging link from the second asset tag.
A position location system, comprising:
- a first asset tag configured to receive a request from an access point over a messaging link to perform a ranging operation;
- and
- a second asset tag configured to receive a first ranging pilot signal from the first asset tag over a ranging link, and further configured to transmit a second ranging pilot signal to the first asset tag over the ranging link,
- in which the first asset tag receives the second ranging pilot signal from the second asset tag and the ranging operation is performed based at least in part on the first ranging pilot signal and the second ranging pilot signal.
An apparatus for position location, comprising:
- means for receiving, over a messaging link, a request from an access point of a position location system to perform a ranging operation between a first asset tag and a second asset tag of the position location system;
- means for transmitting, by the first asset tag, a first ranging pilot signal on a ranging link to enable the ranging operation between the first asset tag and the second asset tag;
- and
- means for receiving, by the first asset tag, a second ranging pilot signal on the ranging link from the second asset tag.
A computer program product for position location, comprising:
- a non-transitory computer-readable medium having non-transitory program code recorded thereon, the program code comprising:
- program code to receive, over a messaging link, a request from an access point of a position location system to perform a ranging operation between a first asset tag and a second asset tag;
- program code to transmit, by the first asset tag, a first ranging pilot signal on a ranging link to enable the ranging operation between the first asset tag and the second asset tag;
- and
- program code to receive, by the first asset tag, a second ranging pilot signal on the ranging link from the second asset tag.
A position location method, comprising:
- requesting a ranging operation between a first asset tag and a second asset tag over a messaging link, so that a first ranging signal is transmitted on a ranging link between the first asset tag and the second asset tag, and a second ranging signal is transmitted on the ranging link between the second asset tag and the first asset tag;
- and
- determining a range between the first asset tag and the second asset tag based at least in part on the first ranging signal and the second ranging signal.
