| 摘要 | An exemplary method includes: obtaining I and Q complex signal parameters of signals received from a mobile tag at each of at least three antenna elements forming part of a positioning device; extracting an identifier modulated onto the signals received from the mobile tag; and transmitting the I and Q complex signal parameters and the identifier to allow a position calculating device to calculate a bearing of the mobile tag from the positioning device, wherein transmitting the I and Q complex signal parameters and the identifier comprises the positioning device wirelessly broadcasting the I and Q complex signal parameters and the identifier. An exemplary apparatus and computer readable medium configured to perform the method are also disclosed. | ||

| 主权项 | 1. A method comprising: obtaining in-phase (I) and quadrature (Q) complex signal parameters of Bluetooth signals received from a mobile tag at each of at least three antenna elements forming part of a positioning device; extracting an identifier modulated onto the Bluetooth signals received from the mobile tag; and transmitting the I and Q complex signal parameters and the identifier, thereby to allow a position calculating device to calculate a bearing of the mobile tag from the positioning device. | ||
