Digital Global Systems and OnGo Alliance Collaborate
In a significant stride towards enhancing wireless communication, Digital Global Systems (DGS) is joining forces with the OnGo Alliance. Their combined expertise is driving the creation of comprehensive best practices designed to tackle the ever-growing challenges of network interference, particularly relevant in the spectrum shared under the Citizens Broadband Radio Service (CBRS).
Understanding the Challenges of Network Interference
The increased deployment of private wireless networks has underscored the urgency of addressing potential interference. With more organizations opting for cost-efficient solutions like CBRS shared spectrum, the risk of service disruption rises. As enterprises strive for improved productivity and operational efficiency using technologies such as autonomous robots and predictive maintenance, ensuring reliable communication becomes paramount.
Best Practices for Spectrum Sharing
To counter the challenges associated with interference, DGS and the OnGo Alliance have co-developed a document that outlines essential practices for successful coexistence. This document emphasizes the importance of sharing detailed environmental and network data among private wireless network operators and CBRS spectrum allocation service (SAS) providers. By promoting collaboration, these entities can optimize the shared spectrum usability.
Three Tiers of CBRS Shared Spectrum Users
CBRS shared spectrum is divided into three distinct tiers. Tier 1 users, primarily military incumbents, enjoy the highest level of protection. Tier 2 users hold Priority Access Licenses (PAL), while Tier 3 comprises General Authorized Access (GAA) users. Currently, GAA users encounter limitations arising from static propagation models that do not fully account for real-world conditions. However, integrating local RF measurements can refine these models, enhancing operational reliability.
A Commitment to Innovation and Improvement
Alan Ewing, Executive Director of the OnGo Alliance, stated, “The potential for interference increases as CBRS private wireless networks proliferate. Our coalition aims to safeguard all users while fostering the growth of reliable CBRS applications. Our revised practices build upon the enhancements of CBRS 2.0, which have improved operational reliability.”
Key Elements of Best Practices
The document identifies several critical areas addressed in the best practices:
- Interference Types: The classification of various interference types that GAA users may face, such as co-channel and adjacent-band interference.
- Effects of Interference: Insights into how various interferences affect network performance, bandwidth, and coverage.
- Network Optimization: Recommendations for optimizing network configuration and parameters to minimize interference.
- Monitoring and Maintenance: Importance of ongoing performance monitoring to adapt to environmental changes effectively.
- Collaborative GAA Coexistence: Framework established for developing interference-minimization frequency plans.
- GCA Frequency Plan: Allocation strategies for CBSDs to sustain operational integrity.
- Reporting Interference: Templates provided for effectively reporting interference incidents to SAS administrators.
Looking Ahead with Advanced Technology
DGS has committed to addressing these challenges over the last decade, developing a patent portfolio that harnesses artificial intelligence and machine learning for advanced RF signal processing. DGS Chairman and CEO Fernando Murias expressed enthusiasm for collaborating with the OnGo Alliance, emphasizing the need for a sustainable approach to CBRS spectrum sharing.
The Future of RF Data and Network Self-Optimization
Leveraging RF data collected via DGS sensor technology will ultimately empower network operators, SAS providers, and enterprises with enhanced awareness and management capabilities. This innovation presents significant opportunities for real-time service optimization, giving a comprehensive view of how RF dynamics impact operational services.
