Wireless Access Point Association Across Mixed Protocol Versions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face interoperability issues when stations with different incremental versions of a communication protocol attempt to connect, leading to some stations being unable to access the most recent functionalities due to beacon data compatibility problems.
Innovation Solution
A method involving a network-management equipment that manages multiple access points, prioritizes stations to connect to the most recent network version by adjusting signal parameters and performing disassociations if necessary, and provides software updates or equipment changes to ensure compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the residential gateway sends beacons in accordance with the 802.11ax amendment indicating support for the current version and all previous versions, then interoperability with stations supporting previous versions is improved, but the beacon data becomes too large for stations designed to process only beacons with smaller data quantities to connect
Solution Approach 1:
The patent divides the wireless network into multiple separate networks, each supporting a specific protocol version (e.g., one network for 802.11ax, another for 802.11ac). This segmentation allows each network to have beacons optimized for its target station population, avoiding the need to include all version information in a single beacon while maintaining overall system interoperability.
2Adaptability or versatility
If the residential gateway intentionally limits the technology supported by the network to a lower version, then stations supporting only that version can connect, but stations supporting the more recent version cannot benefit from the latest functionalities
Solution Approach 1:
The patent segments the network into multiple protocol-version-specific networks, allowing each station to connect to the network matching its capability. This enables stations with older protocols to access the network while stations with newer protocols can access the most recent functionalities on their designated network.
Solution Approach 2:
The patent introduces a new dimension of network differentiation by creating separate networks for different protocol versions on the same physical frequency band. This allows the system to simultaneously serve multiple station types without forcing a single technology level, thereby resolving the contradiction between compatibility and functionality access.
3Adaptability or versatility
If a second network supporting a lower version is created within the same residential gateway, then stations supporting only that version can connect, but 802.11ax stations can also connect to the second network preventing them from benefiting from the latest functionalities
Solution Approach 1:
The patent applies local quality by making each network have distinct characteristics optimized for its target audience. The first network is optimized for 802.11ax stations with advanced functionalities, while the second network is optimized for 802.11ac stations with simpler requirements. This differentiation ensures that 802.11ax stations preferentially connect to the first network to access latest functionalities.

AI summary
A method for managing by management equipment including a first access point of a first network and a second access point of a second network, the first network having functionalities superior to the second network, each access point sending beacons, a station being able to process the beacons sent by the first and second access points or being able to process only the beacons sent by the second access point, the second access point performs the steps of: receiving an association request coming from a station, checking whether the station is able to process the beacon sent by the first access point, rejecting the association request if the station is able to process the beacons sent by the first access point, and associating the station if the station is not able to process the beacons sent by the first access point.
