Problems solved by technology

However, many receivers often suffer from a lack of processing power and are therefore unable to analyze all signals conveyed within the system
Since signal processing activities can often be computationally intensive, the limited computational power of the receiver may result in missed communications due to the receiver's inability to analyze incoming signals at the rate at which communications are received
Lost or missing communications can cause system latency and location failures for RTLS solutions

Abstract

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.

Description

technical field [0001] Embodiments of the present invention relate generally to the field of wireless local area networks (WLANs), and more particularly, embodiments of the present invention relate to real-time location systems and WLANs. Background technique [0002] As the use of portable computers (such as "laptop," "notebook," and "pen" computers) is becoming more common in office environments, industrial environments, homes, retail stores, and other locations, wireless local area networks (WLANs) And real-time location systems (RTLS) are becoming more common. As the availability and cost of wireless networking technologies have increased, WLAN receivers have been developed that can implement real-time location. However, many receivers often suffer from a lack of processing power and are therefore unable to analyze all signals communicated within the system. Since signal processing activities may often be computationally intensive, the limited computational capabilitie...
