Post-Deployment FWA Device Provisioning via Mobile Scan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for provisioning cellular network-connected devices, such as Fixed Wireless Access (FWA) devices, require pre-installed provisioning information at the factory, leading to operational inefficiencies and limitations in updating settings, especially for 5G devices operating on high-band spectrums like mmWave, which have limited coverage and are prone to signal interruptions.
Innovation Solution
A system and method for provisioning FWA devices that allows for the receipt and installation of provisioning information post-deployment using a mobile device, which scans identification information from the FWA device and retrieves necessary settings from a server, enabling cellular connectivity and subsequent updates over the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If provisioning information is pre-installed at the factory, then device can establish cellular connectivity initially, but operational efficiency decreases and updates are limited
Solution Approach 1:
The patent transforms the static provisioning model (factory-pre-installed) into a dynamic model where provisioning information can be remotely updated. The system allows provisioning data to be modified over-the-air through cellular network connections, enabling the device to adapt to network changes, carrier updates, and configuration changes without physical intervention or factory reprogramming.
Solution Approach 2:
The patent introduces a provisioning server as an intermediary between the device and the cellular network operator. This server stores provisioning information and distributes it to devices as needed, enabling centralized management and updates of provisioning data without requiring factory reconfiguration or physical media changes.
2Adaptability or versatility
If provisioning information is fixed at factory, then product variation is reduced, but adaptability to different networks and updates is limited
Solution Approach 1:
The provisioning server acts as an intermediary that manages the complexity of provisioning information storage, retrieval, and distribution. Instead of embedding all provisioning logic and data within the device, the server handles the complex tasks of maintaining provisioning databases, generating update packets, and managing multiple carrier configurations, thereby reducing device complexity while enhancing adaptability.
Solution Approach 2:
The patent creates a universal provisioning system that can serve multiple carriers and device types through a single infrastructure. The provisioning server and mobile device application can handle different cellular networks, frequency bands, and device configurations, making the system adaptable to various networks without requiring device-specific customization beyond initial identification.
3Speed
If mmWave technology is used for 5G, then data speed increases, but coverage area decreases due to propagation losses
Solution Approach 1:
The patent implements feedback mechanisms where the mobile device application monitors cellular signal conditions, connection status, and provisioning effectiveness. This feedback loop allows the system to detect when mmWave connections are experiencing propagation losses or disconnections and trigger appropriate responses, such as retrieving updated provisioning information or switching to alternative network configurations, thereby mitigating the coverage limitations of mmWave technology.
Data Source
AI summary
A Fixed Wireless Access (FWA) device can include identification information disposed on an exterior surface of the FWA device. The FWA device can be configured to receive over a local communication network from a mobile device, provisioning information associated with the FWA device based on the identification information and install the provisioning information in a memory unit. The FWA device can establish cellular connectivity with a network base station based on the provisioning information. The provisioning information can be obtained by the mobile device scanning the identification information, providing the identification information to a server, and receiving the provisioning information from the server based on the identification information.
