1Ease of operation
If manual selection of tilt angles is used for configuring infrastructure equipment, then ease of operation is maintained, but device complexity and scalability deteriorate for larger sets of equipment
Solution Approach 1:
The system enables self-service configuration by automatically calculating and applying tilt angles to infrastructure equipment based on network density information and geographic data. The configuration process no longer requires manual intervention for each equipment item, allowing the system to self-configure and scale automatically.
Solution Approach 2:
The patent changes the configuration parameter from manual tilt angle selection to automated calculation based on network density parameters. By transforming the configuration process into a parameter-driven automatic calculation, the system maintains operational simplicity while eliminating manual configuration complexity.
2Ease of operation
If manual selection of tilt angles is used, then configuration simplicity is maintained, but signal interference management and coverage optimization deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms by using network density information and geographic data to automatically calculate optimal tilt angles. The configuration process continuously references network conditions and equipment locations to determine appropriate tilt angles, ensuring optimized signal coverage without manual intervention.
Solution Approach 2:
The patent applies preliminary action by pre-calculating optimal tilt angles based on network density information and geographic data before deployment. This advance calculation ensures that signal coverage and interference management are optimized from the outset, eliminating the need for manual adjustment while maintaining configuration simplicity.
3Productivity
If automated tilt angle calculation is implemented, then scalability and signal coverage optimization improve, but system complexity and computational requirements increase
Solution Approach 1:
The system achieves universality by using a single automated calculation process that applies to all infrastructure equipment across the network. The same algorithm and data sources (network density information, geographic data) serve all equipment items, enabling scalable configuration without requiring equipment-specific manual setup procedures.
Solution Approach 2:
The patent replaces the mechanical/manual configuration process with an automated computational system. By substituting manual tilt angle selection with automated calculations based on network density and geographic data, the system achieves scalability while managing complexity through standardized computational processes.
4Reliability
If tilt angles are adjusted to reduce signal interference, then signal quality improves, but coverage area and network capacity deteriorate
Solution Approach 1:
The system applies local quality by calculating distinct tilt angles for different infrastructure equipment based on their specific geographic locations and network density conditions. Each equipment item receives customized tilt angle configuration optimized for its local environment, allowing signal quality improvement without uniformly reducing network capacity across the entire network.

AI summary
Traditional configuration of infrastructure equipment relates to the adjustment of horizontal tilt for antennas. Given the potential overlap of infrastructure equipment, varying tilt angles can result in either interference with nearby equipment (“over-tilt”) or reduced coverage areas within a specific infrastructure equipment (“under-tilt”). A tool for determining appropriate tilt angles for infrastructure antennas across a mobile network is provided. The tool automatically determines a range of tilt angles between a selected source antenna and adjacent antennas and optimizes based on a threshold intersecting point. Additionally, the tool can update calculated tilt angles based on network congestion information.
