发明名称 Low energy signaling scheme for beacon fencing applications
摘要 Systems, methods, and devices of the various embodiments provide modified frequency hopping patterns that enable synchronization of a wireless tracking device with a beacon signal that defines a predetermined area (i.e., beacon fence). In an embodiment, a beacon may transmit a beacon signal according to a modified frequency hopping pattern and a wireless tracking device may receive the beacon signal by tuning a receiver according to the frequency hopping pattern. In an embodiment, the modified frequency hopping pattern may include a reference frequency generated at a high redundancy pattern multiplexed with a pseudo random sequence of frequencies. In an embodiment, the packets of the beacon signal transmitted at the reference frequency may include an indication of the next frequency according to the modified frequency hopping pattern.

主权项 1. A method of generating frequency hopping signals of a beacon to facilitate synchronization by a wireless tracking device, comprising: generating a high redundancy pattern of a reference frequency; generating a pseudo random sequence of frequencies, wherein each frequency of the pseudo random sequence of frequencies is different than the reference frequency; and multiplexing the high redundancy pattern of the reference frequency with the pseudo random sequence of frequencies to generate a modified frequency hopping pattern.
