WLAN Uplink Broadcast Service Without Formal Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies are inefficient for establishing wireless connections between wireless devices and access points, particularly for IoT devices, leading to slow or undesirable connection processes.
Innovation Solution
Implementing an uplink broadcast service via a wireless local area network (WLAN) that allows wireless devices to transmit data to a remote destination without a formal wireless association, using an access point to forward the data and optionally embed additional information before transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless association procedures are used for IoT devices, then connection establishment follows standardized protocols, but the connection process becomes slow and complex
Solution Approach 1:
The patent segments the traditional association process by introducing a separate uplink broadcast service channel that operates independently from the formal association procedure. This allows IoT devices to transmit data through a dedicated broadcast mechanism rather than going through the complete association handshake, effectively dividing the connection establishment into optional formal association and immediate broadcast data transmission.
Solution Approach 2:
The access point performs preliminary actions by maintaining an uplink broadcast service that is always active and ready to receive transmissions. The AP pre-configures broadcast channels and monitoring mechanisms before any IoT device needs to send data, eliminating the need for real-time negotiation and setup during the connection process.
2Reliability
If formal wireless association is required for data transmission, then network security and protocol compliance are maintained, but device complexity and connection overhead increase
Solution Approach 1:
The patent introduces an intermediary uplink broadcast service mechanism that mediates between IoT devices and the network. This broadcast service acts as a middle layer that handles data transmission without requiring full association, simplifying the device's interaction with the network while the access point maintains security controls and protocol compliance on its end.
Solution Approach 2:
The patent applies partial action by implementing only the essential data transmission functionality through broadcast without requiring the complete association procedure. IoT devices perform just enough action to send broadcast data without undergoing the full association ritual, while the network maintains sufficient control to ensure security and compliance.
3Productivity
If uplink broadcast service is implemented, then data transmission efficiency improves, but network traffic management complexity increases
Solution Approach 1:
The access point is designed with universal functionality to handle both traditional associated transmissions and uplink broadcast transmissions through a unified architecture. The broadcast service leverages existing AP capabilities for frame reception, processing, and forwarding, allowing the same device to perform multiple functions without requiring separate specialized hardware or complex management systems.

AI summary
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for providing uplink broadcast service connectivity via a wireless local area network (WLAN). In some implementations, a wireless device may transmit an uplink communication to an access point (AP) that supports uplink broadcast services, and the AP may forward the uplink communication to a remote destination indicated in the uplink communication. In some implementations, the wireless device may be in an unassociated state and may transmit the uplink communication without establishing a formal wireless session with the AP. The uplink communication may include a request for the AP to embed AP-provided data to the uplink communication before forwarding it the remote destination. This disclosure includes techniques to prevent flooding and unauthorized uplink communications being used for a denial of service attack on the remote destination.
