Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication signal propagation is affected by various environmental and geographical factors, leading to inconsistent connection quality and coverage issues, particularly in rural areas where terrain and foliage obstruct signal transmission.
Innovation Solution
The use of pulsed laser energy to enhance signal propagation by ionizing the air and reducing moisture in the communication channel, thereby improving reflection, diffraction, and scattering characteristics, and mitigating the effects of environmental conditions such as clouds and foliage, using laser emitters mounted on base stations or structures like buildings and trees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laser energy is used to clear propagation paths and reduce moisture, then signal strength and network coverage are improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent introduces laser emitters as intermediary devices mounted on base stations to clear propagation paths by ionizing air and reducing moisture. These laser emitters act as mediators between the base station and mobile devices, improving signal propagation through environmental modification rather than directly enhancing the communication signals themselves.
Solution Approach 2:
The patent changes physical parameters of the propagation medium by using laser energy to ionize air molecules and reduce moisture content. This modifies the electrical and optical properties of the atmosphere along the signal path, thereby improving signal strength and reducing attenuation without changing the communication equipment itself.
2Reliability
If laser emitters are mounted on base stations to clear propagation paths, then network coverage in rural areas is improved, but cost of deployment and maintenance increases
Solution Approach 1:
The patent makes base stations multi-functional by mounting laser emitters on them, allowing the same infrastructure to serve both traditional communication functions and path-clearing functions. This reduces the need for separate deployment of laser devices and leverages existing base station locations, particularly in rural areas where coverage is needed.
Solution Approach 2:
The laser emitters are integrated into base stations and operate autonomously to clear propagation paths. The system self-manages the path clearing function without requiring additional manual intervention or separate control infrastructure, reducing maintenance complexity and operational costs.
3Reliability
If pulsed laser is used to ionize air and reduce moisture, then signal propagation characteristics are improved, but energy consumption increases
Solution Approach 1:
The patent employs pulsed laser emission rather than continuous operation. The laser emits energy in periodic pulses timed to coincide with signal transmission intervals, clearing the propagation path only when needed. This periodic action reduces overall energy consumption compared to continuous laser operation while maintaining effective signal propagation during active communication periods.

AI summary
A system uses pulsed lasers to enhance a signal propagation path in a telecommunications network. The system can estimate a signal propagation path, which varies based on a current location of a mobile device relative to a base station. The system can detect a propagation loss due to a condition of a propagation medium including the signal propagation path and determine whether the mobile device is in Line-of-Sight (LOS) of a laser emitter. In response to detection of the propagation loss, the laser emitter can emit a pulsed laser that can enhance signal propagation by mitigating the propagation loss on the signal propagation path. The pulsed laser has a propagation path overlapping the signal propagation path when the mobile device is in LOS of the laser emitter, which is mounted on the base station.
