SYNCHRONIZED CHANNEL ACCESS COEXISTENCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18475631 titled 'SYNCHRONIZED CHANNEL ACCESS COEXISTENCE
Simplified Explanation
The patent application abstract describes methods, devices, and systems for synchronized channel access in wireless communication devices. Here are some key points from the abstract:
- A group of access points can schedule synchronized channel access periods by transmitting quiet elements periodically.
- Quiet elements establish recurring quiet periods during which legacy devices cannot transmit.
- Access points may transmit quiet override elements to indicate to other access points that they can contend for access during the quiet period.
- An access point that wins contention after consecutive synchronized channel access periods may be entitled to an extended TXOP.
Potential Applications
The technology described in this patent application could be applied in various wireless communication systems where coexistence among devices supporting synchronized channel access and legacy devices is necessary. It can be particularly useful in environments with high-density wireless networks or where interference needs to be minimized.
Problems Solved
This technology solves the problem of efficiently managing channel access in mixed networks where some devices support synchronized access while others do not. By establishing recurring quiet periods and allowing contention during these periods, the system can ensure fair access to the channel for all devices.
Benefits
The benefits of this technology include improved coexistence among different types of wireless devices, increased efficiency in channel access, reduced interference, and potentially higher throughput in wireless networks.
Potential Commercial Applications
Potential commercial applications of this technology could include deployment in enterprise wireless networks, public Wi-Fi hotspots, smart home devices, IoT networks, and any other environment where multiple wireless devices need to share the same channel efficiently.
Possible Prior Art
One possible prior art for this technology could be existing methods for managing channel access in wireless networks, such as CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) protocols or TDMA (Time Division Multiple Access) systems. These traditional methods may not address the specific challenges of coexistence between synchronized and legacy devices as described in the patent application.
Unanswered Questions
How does the system handle potential conflicts between synchronized access points during contention periods?
The abstract does not provide details on how conflicts between synchronized access points are resolved when contending for channel access. Further information on the contention resolution mechanism would be helpful to understand the system's overall efficiency.
What is the impact of introducing synchronized channel access on the overall network latency?
The abstract does not mention the potential impact of introducing synchronized channel access on network latency. Understanding how this technology affects latency compared to traditional methods would be crucial for assessing its performance in real-world applications.
Original Abstract Submitted
This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period. In some other implementations of synchronized channel access, an access point supporting synchronized channel access that wins contention after one or more consecutive synchronized channel access periods during which no other synchronized access points won contention, may be entitled to an extended TXOP.
