Single RF Modem Network Attachment Arbitrator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in providing efficient access to multiple wireless networks from a single device, particularly in supporting high-demand services like wireless video, due to the large data transmission requirements and limited capacity of conventional two-way networks.
Innovation Solution
A wireless communication device equipped with a single radio frequency modem that alternates between two or more networks by attaching and detaching from them based on predetermined timing information for data bursts, using a network attachment arbitrator module to control the modem and collect data from a second network during event times, while maintaining connection with a first network during non-event times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single RF modem is used to access multiple wireless networks, then device complexity is reduced, but the ability to simultaneously receive data from multiple networks is limited
Solution Approach 1:
The system uses periodic time slicing to alternately attach the single RF modem to different wireless networks. The modem switches between networks at predetermined intervals, allowing it to access event data from a second network while maintaining connection to a first network, thereby enabling multiple network access with reduced device complexity
Solution Approach 2:
The system performs preliminary actions by detaching from the first network at a predetermined time before the start time of a selected event on the second network, and re-attaching after data collection. This timing-based coordination allows efficient use of the single modem to capture event data without missing information
2Productivity
If a separate video service network is implemented, then video data transmission efficiency is improved, but network infrastructure complexity increases
Solution Approach 1:
The system enables a single wireless network infrastructure to serve multiple functions by allowing subscriber stations to access both conventional two-way service networks and video service networks using the same RF modem. This multi-functionality approach provides efficient video data transmission without requiring completely separate network infrastructure
3Reliability
If a subscriber station attaches to multiple networks simultaneously, then network coverage and service availability are improved, but data transmission efficiency decreases due to network switching overhead
Solution Approach 1:
The system employs periodic switching between networks with carefully timed intervals. The modem alternates between attaching to the first network and the second network at predetermined times, ensuring that event data is captured during second network attachment while maintaining service availability through first network connection at other times
Solution Approach 2:
The system dynamically adjusts network attachment timing based on event schedules. The subscriber station detaches from the first network at a predetermined time before a selected event starts on the second network, and re-attaches after the event, optimizing data transmission efficiency while maintaining service reliability

AI summary
Methods and devices for operating a wireless communication device that can communicate with at least two different co-located APs are described. The device may receive, from a first AP, information corresponding to a second AP of the co-located APs. The information corresponding to the second AP may include state information of the second AP. The device may establish a first wireless link with the first AP using a first frequency of the first AP and establish a second wireless link with the second AP using a second frequency which is different than the first frequency. The device may simultaneously receive first data from the first AP and second data from the second AP.
