Beacon Extension Segmentation for Device-Specific Wireless Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in processing large beacon frames, leading to increased processing power consumption and resource utilization due to the need to parse irrelevant information for different device types, which can result in disassociation and management frame overhead.
Innovation Solution
The implementation of beacon extension design, where beacon frames are segmented into common and type-specific segments, allowing devices to parse only relevant information based on their type, with separate periodicities for different types, reducing processing load and optimizing message container sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beacon frames contain all possible device type information, then all device types can be supported, but processing power consumption increases
Solution Approach 1:
The beacon frame is divided into a common information field and multiple type-specific information fields. Each type-specific field contains parameters relevant to a particular device type. Devices only parse the common field and their specific type field, ignoring other type fields, thereby reducing processing power consumption while maintaining support for multiple device types.
2Loss of information
If beacon frames contain all device type parameters, then complete information is provided, but message container size increases
Solution Approach 1:
The message container is segmented into a common information portion and multiple type-specific portions. Each type-specific portion contains only the parameters relevant to that device type. This segmentation reduces the overall message container size transmitted over the air while ensuring that each device receives complete information for its specific type without unnecessary data.
3Loss of information
If devices parse all beacon frame segments, then no information is missed, but processing time increases
Solution Approach 1:
The beacon frame is segmented with clear delimiters between common and type-specific fields. Devices can quickly identify and parse only the common field and their specific type field, skipping other type fields entirely. This selective parsing approach maintains information completeness for relevant data while significantly reducing processing time.
Solution Approach 2:
Type-specific information fields are extracted as separate, identifiable segments within the beacon frame. Each device type can extract and process only its relevant field, eliminating the need to parse irrelevant type-specific information from other devices, thereby reducing processing time while maintaining information completeness.
4Reliability
If all devices process complete beacon frames, then compatibility is maintained, but resource utilization increases
Solution Approach 1:
The beacon frame structure is segmented into a common field that all devices must process and multiple type-specific fields that only relevant devices process. This segmentation maintains compatibility across all device types while reducing resource utilization, as each device only processes the common field plus its specific type field, ignoring other type fields.

AI summary
This disclosure provides methods, components, devices and systems for beacon extension design. A wireless station may receive one or more beacon containers including a beacon extension container and may communicate one or more messages based on segments of the one or more beacon containers that are relevant for the wireless station. Each segment may correspond to a respective device type. Each segment may include a frame check sequence and a message integrity code corresponding to each respective segment. The wireless station may receive a first beacon container according to a first periodicity and a second beacon container according to a second periodicity. The first and second periodicities may have different values based on the device type of the wireless station. The beacon containers may include type-specific segments corresponding to the device type. Each type-specific segment may include parameters or updated information for the wireless station.
