Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If NAN peer-to-peer groups are formed for direct device communication, then information exchange efficiency is improved, but channel congestion and interference increase
Solution Approach 1:
The patent introduces a Wi-Fi access point as an intermediary to monitor NAN group formations and track mobile device locations. The access point detects NAN communications, determines device destinations, and coordinates channel assignments to prevent interference, thereby maintaining P2P communication efficiency while reducing channel congestion
Solution Approach 2:
The system dynamically changes the wireless channel parameter based on predicted device destinations and current channel conditions. When a NAN group is detected, the access point assigns different channels to different groups or time slots, adjusting the channel parameter to avoid congestion and interference while preserving communication efficiency
2Reliability
If mobile devices form synchronized NAN groups at rendezvous points, then direct communication capability is improved, but radio interference increases in high-density venues
Solution Approach 1:
The patent segments the wireless medium by assigning different channels to different NAN groups based on their predicted destinations and locations. The Wi-Fi access point divides the venue into multiple spatial zones and allocates specific channels to groups in different zones, allowing direct communication within groups while minimizing radio interference between groups
Solution Approach 2:
The system dynamically adjusts channel assignments as mobile devices move through the venue. The access point continuously monitors device locations, predicts destinations, and reassigns channels in real-time to maintain reliable direct communication while adapting to changing spatial conditions and reducing interference

AI summary
Presented herein are methodologies for managing radio resources in a venue that implements a high density wireless infrastructure. The methodology includes detecting, using wireless access points, neighbor awareness networking (NAN) communications broadcast by a mobile device, determining a wireless channel on which the mobile device is sending the NAN communications, predicting a destination of the mobile device based on a path, through a predetermined venue, being taken by the mobile device, the path being detected using the wireless access points; and implementing a radio resource management remediation technique to reduce radio interference that is expected to be caused by the NAN communications broadcast by the mobile device at the destination based on the wireless channel and the destination.
