Small Cell Networking Device Antenna Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small cell networking devices are proprietary and require individual integration with each mobile network operator's (MNO) network, limiting their deployment and functionality, especially when mounted on streetlight fixtures for combined light and cellular network services.
Innovation Solution
A small cell networking device with an integrated light sensor, processor-based light control circuit, and multiple networking modules for different MNOs, mounted on a streetlight fixture, providing cellular and WiFi services while controlling light output based on ambient conditions, and capable of concurrent communication sessions across different networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If small cell networking devices are proprietary and individually integrated with each MNO's network, then network operator control and customization are improved, but deployment complexity and device complexity increase
Solution Approach 1:
The networking device is designed with multiple cellular transceivers supporting different MNO networks simultaneously, along with WiFi and Bluetooth capabilities. This multi-functional design allows a single device to serve multiple network operators without requiring separate proprietary integrations, thereby reducing deployment complexity while maintaining adaptability to different MNOs through software-based network selection and switching.
2Adaptability or versatility
If multiple antennas are integrated into the networking device for different networks, then network coverage and functionality are improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
Multiple antennas for different cellular networks, WiFi, and Bluetooth are physically integrated into a single networking device housing. The device combines these previously separate components into one unified unit with shared power supply, control circuitry, and mounting mechanism. This merging approach maintains comprehensive network coverage functionality while simplifying manufacturing through standardized production processes for integrated devices rather than multiple separate components.
3Productivity
If small cell devices are mounted on streetlight fixtures for combined services, then infrastructure utilization and productivity are improved, but integration complexity and device complexity increase
Solution Approach 1:
The networking device integrates multiple communication functions (cellular, WiFi, Bluetooth) and light control capabilities into a single unit that can be mounted on streetlight fixtures. This universal design allows the device to provide both networking services and streetlight control through a unified platform, reducing integration complexity compared to separate systems while maximizing infrastructure utilization by combining multiple services on existing streetlight poles.

AI summary
A small cell networking device includes a compartment in which at least one printed circuit board (PCB) is mounted. At least three networking modules are mounted on the at least one PCB. A first one of the networking modules is arranged as a gateway to a first wireless network. A second one of the networking modules is arranged as a gateway to a second wireless network. A third one of the networking modules monitors network traffic in the first wireless network or second wireless network. First and second antennas are mounted to a first surface of the compartment, between a second surface of the compartment and the PCB. A third antenna is mounted to the second surface of the compartment between the second surface of the compartment and the PCB. The first, second, and third antennas are respectively coupled to the first, second, and third networking modules.
