Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless data relays generate unwanted radio interference and suffer from excessive radio interference due to ineffective control over their frequency channels, leading to suboptimal performance in wireless communication networks.
Innovation Solution
The implementation of radio circuitry and control circuitry in wireless data relays that scan and attach to specific allowed frequency channels instead of the entire frequency band, reducing interference by locking onto and using only the channels with minimal interference, as signaled by the wireless network, and adjusting accordingly based on network feedback.

Engineering Contradiction Analysis
1Area of stationary object
If wireless data relays use the entire frequency band for communication, then coverage area and service capacity are improved, but radio interference increases
Solution Approach 1:
The patent segments the frequency band into multiple frequency channels and assigns specific channels to wireless data relays based on their location and interference conditions. Instead of allowing relays to use the entire frequency band, the system divides the band and allocates subsets to different relays, thereby reducing overall interference while maintaining coverage.
Solution Approach 2:
The patent implements location-specific frequency channel allocation where each wireless data relay is assigned frequency channels appropriate to its geographic location and interference environment. The network controller determines which channels to allocate based on local interference conditions, ensuring that each relay operates with optimal frequency resources for its specific area.
2Adaptability or versatility
If wireless data relays scan the entire frequency band, then channel selection flexibility is improved, but interference mitigation capability deteriorates
Solution Approach 1:
The patent performs preliminary frequency channel allocation before wireless data relays begin operation. The network controller pre-determines which frequency channels to assign to each relay based on initial interference assessments and location information. This preliminary action allows relays to operate with predetermined channels that are optimized to avoid interference, while still maintaining flexibility for future reconfiguration.
Solution Approach 2:
The patent implements a feedback mechanism where wireless data relays report their operating conditions and interference levels to the network controller, which then adjusts frequency channel allocations accordingly. This closed-loop system maintains adaptability by allowing dynamic reconfiguration of frequency assignments based on real-time feedback about interference conditions and relay performance.
3Device complexity
If wireless data relays operate without frequency channel control, then device complexity is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent introduces a network controller as an intermediary that manages frequency channel allocation for wireless data relays. Instead of requiring complex frequency control logic within each relay device, the network controller centrally manages frequency assignments and provides clear instructions to relays. This intermediary approach maintains low device complexity at the relay level while ensuring high communication reliability through coordinated frequency management.

AI summary
A wireless data relay has radio circuitry to wirelessly scan a frequency band having frequency channels. The radio circuitry attaches to a wireless network over the frequency band. The radio circuitry receives signaling from the wireless network indicating allowed frequency channels and transfers the signaling to control circuitry. In the wireless data relay, the control circuitry processes the signaling to direct the radio circuitry to use the allowed frequency channels instead of the frequency band. In response, the radio circuitry wirelessly scans the allowed frequency channels instead of the frequency band. The radio circuitry wirelessly re-attaches to the wireless communication network over the allowed frequency channels. The radio circuitry exchanges user data with the UEs.
