Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of new wireless devices using high-performance communication protocols, such as 5G, in wireless networks can create data bottlenecks and performance degradation for existing devices, particularly when the number of devices exceeds a threshold, leading to service limitations for users relying on these protocols.
Innovation Solution
A method and system that manage wireless devices by adjusting the operating parameters of multi-element antennas in access nodes, specifically reducing the number of elements used for transmitting and receiving signals when the number of devices using a high-performance protocol exceeds a threshold, forcing some devices to switch to a lower performance protocol or handover to a different cell, thereby maintaining network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of wireless devices using high-performance protocol (e.g., 5G) increases, then network capacity and data rate requirements are met, but data bottlenecks occur and performance degradation affects existing devices
Solution Approach 1:
The patent dynamically adjusts the operating parameters of multi-element antennas based on the number of connected wireless devices. When the device count exceeds a threshold, the system modifies antenna characteristics (such as beamforming patterns, gain, or radiation patterns) to redistribute network resources and prevent data bottlenecks, thereby maintaining service performance while supporting high network capacity
Solution Approach 2:
The system changes operating parameters of the multi-element antennas (such as element activation, phase shifts, amplitude weights, or frequency allocation) in response to device density. This parameter adjustment allows the network to optimize performance characteristics dynamically, preventing degradation when high-performance protocols are used by numerous devices
2Productivity
If multi-element antennas operate with full elements for high-performance protocols, then data rate and throughput are maximized, but data bottlenecks occur in uplink or downlink paths
Solution Approach 1:
The patent applies partial action by adjusting antenna operating parameters to provide sufficient (but not excessive) resource allocation. When device density is high, the system modifies antenna characteristics to deliver adequate data rates while preventing the harmful effect of data bottlenecks, rather than maintaining full-capacity operation that would cause network congestion
3Adaptability or versatility
If new wireless devices are added to the network using high-performance protocols, then network coverage and device connectivity increase, but performance of services for existing devices is limited
Solution Approach 1:
The system dynamically adapts antenna operating parameters based on the number of connected devices using high-performance protocols. When device connectivity increases beyond a threshold, the system automatically adjusts antenna characteristics to maintain service performance for existing devices, ensuring the network can accommodate new devices without degrading overall reliability

AI summary
Systems, methods, and processing nodes are configured to manage wireless devices in a wireless network, such as a network that employs MIMO techniques, by receiving a request from a new wireless device for access to a wireless network using a first communication protocol, the wireless network using at least two communication protocols simultaneously, determining that a number of wireless devices in the wireless network using the first communication protocol of the at least two communication protocols meets a threshold number of wireless device, and adjusting an operating parameter of a multi-element antenna for communicating signals between an access node and the wireless devices in the wireless network using the first communication protocol when it is determined that the number of wireless devices in the wireless network using the first communication protocol meets the threshold number of wireless devices.
