Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna installations for wireless mesh networks require significant vertical space and remote positioning, leading to inefficient use of real estate and limited access for installation, servicing, and maintenance.
Innovation Solution
A sectorized antenna assembly with a mounting device, support arm, and multiple antenna assemblies that can be mounted on various structures, allowing for compact vertical space usage and adjustable positioning to minimize shadowing and interference, featuring tiltable and offset antenna configurations for enhanced coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antennas are installed remotely and vertically offset from the node to provide sufficient coverage, then wireless coverage is improved, but vertical space consumption increases and component accessibility deteriorates
Solution Approach 1:
The patent transitions from a purely vertical antenna arrangement to a three-dimensional configuration using support arms that extend antennas laterally from the mounting bracket. This allows antennas to be positioned in multiple spatial dimensions (vertical height plus lateral offset), providing sufficient wireless coverage while reducing the vertical space footprint on the support structure.
2Reliability
If antennas are installed remotely and vertically offset from the node, then wireless coverage is improved, but accessibility for installation and maintenance deteriorates
Solution Approach 1:
The support arm acts as an intermediary element between the mounting bracket and the antennas. It provides the necessary spatial separation for wireless coverage while maintaining a mechanical connection that allows for easy installation, adjustment, and maintenance of antenna components without requiring complete disassembly of the entire mounting system.
3Reliability
If multiple antennas are positioned vertically to provide coverage, then wireless coverage is improved, but antenna interference increases due to overlapping positions
Solution Approach 1:
The support arms enable antennas to be positioned in three-dimensional space with both vertical and lateral offsets from the mounting bracket. This spatial separation in multiple dimensions reduces electromagnetic interference between adjacent antennas while maintaining comprehensive wireless coverage through proper positioning of each antenna element.

AI summary
A sectorized antenna assembly includes a mounting device, a support arm, a first antenna assembly, and a second antenna assembly. The mounting device supports the sectorized antenna assembly on a structure, and the support arm is connected to the mounting device and extends outwards from the mounting device in a lateral direction. The first antenna assembly is directly connected to the mounting device. The second antenna assembly is supported by the support arm such that the support arm is between the second antenna assembly and the mounting device and such that the second antenna assembly is offset in the lateral direction from the mounting device compared to the first antenna assembly.
