1Loss of information
If current methods are used to determine available bandwidth by communicating with central servers, then information about node bandwidth can be obtained, but the process becomes time-consuming and affects user experience
Solution Approach 1:
The user device autonomously determines the load measure of wireless nodes by directly analyzing transmitted frames without requiring communication with central servers. The device extracts timing information and device count information from frames independently, eliminating the need for server-based bandwidth information gathering and significantly reducing the time required.
Solution Approach 2:
The system continuously monitors and analyzes frames transmitted by wireless nodes in real-time, maintaining up-to-date load measure information proactively. This preliminary action ensures that when a user device needs to connect or switch nodes, the bandwidth information is already available, eliminating the need for time-consuming on-demand queries to central servers.
2Productivity
If user devices autonomously determine load measures by analyzing transmitted frames, then bandwidth information can be obtained quickly, but the device must process and analyze frame data
Solution Approach 1:
The user device extracts only the specific timing information and device count information needed for load measure calculation from the transmitted frames, rather than processing the entire frame content. This selective extraction approach enables quick bandwidth determination while minimizing the processing complexity by focusing only on the relevant data elements.

AI summary
A method for determining a load measure associated with a wireless communications node, such as a Wi-Fi access point or cellular base station, is described. A time interval measure representing a time interval between frames transmitted by a node is determined, and a number of user devices associated with the node is determined based on information in the frames transmitted by the node. A load measure associated with the node is determined, based at least on the number of user devices associated with the node and the time interval measure. Systems and apparatus are also described.
