WIRELESS CHANNEL ACCESS USING RECEIVER INTERFERENCE ENVIRONMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240260094 titled 'WIRELESS CHANNEL ACCESS USING RECEIVER INTERFERENCE ENVIRONMENT
The abstract of this patent application describes methods, devices, and systems for clear channel assessment (CCA) in wireless local area networks (WLANs). In this innovation, an access point (AP) can detect interfering transmissions from overlapping basic service sets (OBSS) and transmit probe frames to stations (STAs) to gather information on the interference environment.
- Access points (APs) can detect interfering transmissions from overlapping basic service sets (OBSS) in wireless local area networks (WLANs).
- APs can transmit probe frames to stations (STAs) to solicit information on the interference environment observed by the STAs.
- The probe frames are sent when interfering transmissions do not meet interference criteria set by the AP.
- If the interfering transmissions meet the interference criteria, the probe frames are sent after a backoff period to gather information from the STAs.
Potential Applications: - This technology can be applied in various WLAN environments to improve communication quality by assessing and mitigating interference. - It can be used in smart homes, offices, public hotspots, and other wireless networking scenarios.
Problems Solved: - Addresses issues related to interference in WLANs that can degrade network performance and reliability. - Provides a method for APs to proactively assess and manage interference from OBSS.
Benefits: - Enhances the overall performance and reliability of WLANs by effectively managing interference. - Improves the user experience by reducing packet loss and increasing network efficiency.
Commercial Applications: - This technology can be valuable for companies that rely on WLANs for their operations, such as businesses, schools, hospitals, and public venues. - It can also be integrated into networking equipment and devices to enhance their performance in crowded wireless environments.
Questions about Clear Channel Assessment: 1. How does this technology contribute to improving the quality of wireless communications in WLANs? 2. What are the specific criteria used by APs to determine interference and trigger the transmission of probe frames?
Frequently Updated Research: - Stay informed about the latest advancements in CCA technology and research to ensure optimal performance and compatibility with evolving WLAN standards.
Original Abstract Submitted
this disclosure provides methods, devices and systems for clear channel assessment (cca) for wireless communications in wireless local area networks (wlans). in some aspects, an access point (ap) may detect an interfering transmission associated with an overlapping basic service set (obss). the ap may further transmit, to at least one station (sta), a probe frame soliciting information indicating an interference environment observed by the at least one sta when an interfering transmission fails to satisfy an interference criterion associated with the ap. the ap may further transmit the probe frame to the at least one sta after a backoff period when the interfering transmission satisfies the interference criterion associated with the ap.
