Rooftop Mounting Structure for LOS-Stable Wireless Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face interruptions due to loss of line-of-sight (LOS) conditions caused by factors like vegetation growth or new constructions, leading to network failures and the need for frequent field technician interventions to re-align wireless communication nodes.
Innovation Solution
A non-penetrative mounting apparatus for wireless communication nodes using a distributed weight system and support struts to secure nodes on rooftops, ensuring improved LOS conditions, and a mechanical mounting apparatus capable of rotating radio modules to adjust beam directions in response to command signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If penetrative mounting is used to secure wireless communication nodes on rooftops, then the mounting stability is improved, but the rooftop surface is damaged and structural integrity is compromised
Solution Approach 1:
The mounting apparatus uses a distributed weight system with counterweights that balance the load of the wireless communication node without penetrating the rooftop. The counterweights distribute the force across multiple contact points on the rooftop surface, preventing structural damage while maintaining stable mounting.
Solution Approach 2:
The mounting apparatus is divided into multiple separate components including support struts, mounting plates, and counterweight elements that can be independently positioned and adjusted. This segmentation allows the system to achieve stable mounting through distributed forces rather than concentrated penetration points.
2Ease of manufacture
If wireless communication nodes are mounted at fixed positions, then the installation simplicity is improved, but the ability to maintain LOS conditions under environmental changes deteriorates
Solution Approach 1:
The mounting apparatus incorporates adjustable and movable components that allow the wireless communication node to be repositioned dynamically. The support struts and mounting plates can be adjusted to change the node's orientation and position, enabling the system to adapt to environmental changes such as vegetation growth while maintaining LOS conditions.
3Reliability
If field technicians are dispatched frequently to re-align wireless communication nodes, then the LOS conditions are restored, but the loss of time and operational disruption increase
Solution Approach 1:
The mounting apparatus is designed with pre-configured adjustment mechanisms and multiple positioning options that allow for preliminary setup of optimal LOS conditions. The adjustable components enable the system to compensate for anticipated environmental changes such as seasonal vegetation growth without requiring frequent technician interventions.
4Object-affected harmful factors
If non-penetrative mounting is used to protect rooftop surface, then the structural integrity is maintained, but the mounting stability may be reduced
Solution Approach 1:
The mounting apparatus uses a distributed weight system with counterweights that create balanced force distributions across the rooftop surface. This equipotential approach ensures that the mounting forces are evenly distributed without concentrated loads that could damage the rooftop, while maintaining stable mounting through the balanced force system.

AI summary
A wireless communication node of a wireless communication system may include a wireless communication module that is configured to communicate with a satellite (e.g., a low earth orbit satellite) and a mounting unit for mounting the wireless communication module at a ground-based installation site, where the mounting unit is configured to mechanically rotate the wireless communication module in response to receiving a command signal. Further, in at least some implementations, the wireless communication module may have electronic beamsteering capability.
