MmWave Window Refraction for Non-Line-of-Sight Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems using mmWave bands face significant path and barrier losses due to wide beam widths and non-line of sight issues, particularly when the client is located behind barriers like walls or windows, leading to decremental link performance.
Innovation Solution
A wireless communication system that incorporates a barrier, such as a window, with an array of refractive elements to focus electromagnetic radiation onto the receive antenna, enhancing the effective aperture and improving link budget by collectively refracting mmWave signals for better reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If physically small antenna arrays are used, then device portability and cost are improved, but beam width remains wide causing energy loss in transmission
Solution Approach 1:
The patent introduces a barrier with refractive elements as an intermediary component between the transmitter and receiver. This barrier focuses the electromagnetic radiation onto the receive antenna, effectively concentrating the energy that would otherwise be dispersed in wide beams, thereby reducing energy loss without requiring larger antenna arrays
Solution Approach 2:
The patent changes the optical parameters of the barrier by incorporating refractive elements that alter the refraction angle of electromagnetic radiation. By adjusting the refraction characteristics of the barrier, the system can focus energy more effectively, improving energy utilization without increasing antenna array size
2Ease of operation
If the client is located near a barrier inside the customer premises, then installation flexibility is improved, but barrier losses and non-line of sight conditions cause decremental link performance
Solution Approach 1:
The patent converts the harmful effect of the barrier (which causes signal loss and blocks line of sight) into a beneficial focusing element. By adding refractive elements to the barrier, the barrier itself becomes the mechanism that focuses electromagnetic radiation onto the receive antenna, transforming the obstacle into an asset that improves link performance
Solution Approach 2:
The barrier with refractive elements serves as an intermediary that mediates between the transmitter and receiver. Instead of simply blocking the signal, the barrier actively focuses the electromagnetic radiation, enabling reliable communication even when the client is located inside the customer premises behind what would traditionally be considered obstructive barriers
