Surge Suppression System for Wireless Communication Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed wireless communication systems are vulnerable to lightning strikes and power surges due to the increased exposure of DC power lines and fiber optic cables, particularly with radios located outside communication shelters, leading to potential damage to DC power plants and telecommunication equipment.
Innovation Solution
A surge suppression system providing both local and remote protection using waterproof, easy-to-install enclosures with pluggable surge suppression modules and a unique in-line blind mate interface, allowing for hot swapping of surge suppression devices without disrupting radio operations, and a rack mountable surge suppression unit with a hot swappable tray for multiple device replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radios are located outside the communication shelter on the tower, then coverage and system performance are improved, but susceptibility to lightning strikes and power surges increases
Solution Approach 1:
The patent introduces surge suppression devices as intermediary components between the outdoor radios and the power distribution system. These devices act as mediators that block harmful surge currents while allowing normal power flow, thereby protecting the radios from lightning-induced surges without compromising their outdoor deployment and performance benefits.
Solution Approach 2:
The patent segments the power distribution system into multiple protected zones by placing surge suppression devices at different locations - both at the power plant inside the shelter and at outdoor locations near the radios. This segmentation allows each segment to be independently protected, enabling maintenance of one device without affecting others, and providing layered defense against surge attacks.
2Adaptability or versatility
If multiple individual power lines are run to each radio, then power distribution flexibility is improved, but the amount of exposed cabling and risk of surge damage increases
Solution Approach 1:
The patent combines multiple power lines and surge protection functions into integrated surge suppression devices that can handle multiple circuits simultaneously. By merging the protection function across all power lines at a given location, the system maintains the flexibility of individual power distribution while collectively reducing the exposed surface area to surge attacks through shared suppression components.
3Ease of operation
If surge suppression devices are installed in waterproof enclosures with pluggable modules, then ease of maintenance and installation is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic, hot-swappable module designs that allow surge suppression devices to be inserted and removed without powering down the system or requiring complex disassembly. The modular architecture with standardized interfaces enables flexible configuration and easy replacement, making the overall system easier to operate and maintain despite the added complexity of the enclosure and module interfaces.

AI summary
A surge suppression system provides surge protection both locally within the radio station building were the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. An external surge suppression unit provides a waterproof enclosure for both surge suppression devices and fiber optic connectors. A rack mountable surge suppression unit provides local in-line surge suppression protection for the electrical equipment located in the communication station. A unique surge suppression tray is hot swappable so that multiple surge suppression devices can be replaced at the same time without disrupting radio operation. Pluggable surge suppression modules can be used in both the external surge suppression unit and the rack mountable surge suppression unit.
