Abstract
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.
