Wireless Network Modernization: Fully Remote Execution 

A leading wholesale connectivity provider operates a large-scale national network, delivering high-capacity business services through a combination of metropolitan fiber infrastructure and an extensive wireless footprint. As the network expanded over time, it incorporated multiple hardware generations and firmware baselines—creating a need to streamline operations and align with current software standards. 

To improve long-term maintainability, operational consistency, and lifecycle alignment, the operator partnered with Ceragon Professional Services to execute a large-scale, fully remote firmware standardization program. 

Within a matter of weeks, Ceragon successfully upgraded 2,183 network elements, delivering a more unified, supportable, and future-ready network—without disrupting live services. 

THE CHALLENGES

Diverse Firmware Landscape | Large-Scale Complexity | Operational Constraints |  
Lifecycle Alignment 

Standardizing firmware across a nationwide wireless network is a highly complex task, particularly when the environment spans multiple technology generations, thousands of live links, and strict service availability requirements for revenue-generating services. 

As the network evolved, maintaining firmware consistency across this diverse environment became increasingly challenging. The initiative required deep expertise, meticulous planning, and tightly coordinated execution to ensure upgrades could be performed at scale without impacting service continuity. 
Key challenges included:

• Aligning thousands of network elements with current, supported firmware baselines across multiple product generations 
• Managing a highly distributed network while preserving uninterrupted wholesale services  solutions
• Reducing the operational burden on internal engineering and NOC teams 
• Executing upgrades at scale within tightly controlled maintenance windows 
• Ensuring consistent outcomes across a complex environment involving multiple systems, tools, and operational interfaces 

THE SOLUTION

End-to-End Professional Services | Remote Execution | Multi-Generation Expertise  

Ceragon delivered a turnkey professional services engagement, taking full ownership of the firmware standardization program across the nationwide wireless network. Drawing on deep product expertise and proven large-scale execution methodologies, Ceragon managed the entire lifecycle of the project, from assessment through validation, allowing the operator to modernize its network without diverting internal resources. 

The solution included:

• Comprehensive network assessment and upgrade planning. 
• A structured, staged upgrade methodology tailored to multiple product generations and legacy firmware paths. 
• Fully remote execution, eliminating the need for on-site intervention. 
• Cross-regional delivery, with upgrades performed during defined maintenance windows aligned to the network’s operational requirements. 
• Continuous coordination with the operator’s NOC, ensuring full visibility, controlled execution, and risk mitigation throughout the rollout.
