摘要： Provided are architectures, systems, methods, and computer program products for real-time object locating and position determination using frequency channel diversity for transmitting and receiving position determination signals including bursts of location signals. Channelized frequency diversity of a short burst of small location signals that “hop” across multiple frequency channels is used to collectively produce a quasi-wideband position determination signal. Object tags operating with frequency channel diversity for transmitting location signals of position determination signals require low power consumption, but can still efficiently provide adequate position determination signals for reliable position determination.

摘要： Various methods for wireless signal storage with signal recognition detection triggering are provided. One method may include receiving a plurality of wireless signals via a plurality of frequency channels, storing representations of the plurality of wireless signals in a signal buffer, and receiving a trigger request for a signal of interest. In this regard, the trigger request may have been generated based on an analysis of at least one wireless signal within the plurality of wireless signals to thereby identify the signal of interest. The method may also include retrieving a representation of the signal of interest from the signal buffer based on the trigger request, and analyzing the retrieved representation of the signal of interest with associated signal characteristics to determine a location of a source of the signal of interest. Similar apparatuses and computer program products are also provided.
