Extending Multi-Gigabit Broadband Through Existing Coaxial Infrastructure

Regional cable operator Sjoberg's Inc. deployed hardware and software from InCoax Networks and Nokia to resolve the logistical challenges of delivering high-speed telecommunications to multi-dwelling units. The implementation leverages existing wiring to upgrade network bandwidth for residential broadband subscribers across multiple properties.

Client Background and Operational Challenges
Based in Thief River Falls, Minnesota, Sjoberg's Inc. manages broadband networks for residential customers. A primary operational challenge for the company involved upgrading network speeds in multi-dwelling units (MDUs). Extending pure fiber-optic networks directly to individual apartments presents significant structural complexities, requiring invasive construction that disrupts residents and increases labor costs. The operator needed a method to increase bandwidth delivery without initiating extensive cabling projects inside established buildings.

Chosen Technical Solution and Architecture
To achieve these connectivity goals, the operator selected Nokia Gigabit Connect with MoCA Access, which incorporates InCoax Networks technology. Instead of routing new fiber throughout each residential structure, the solution utilizes a Fiber Access Extension architecture. High-speed fiber is delivered to a central access point at the building, and data is subsequently distributed to individual subscriber units using the existing in-building coaxial infrastructure. The initial activation is part of a broader network upgrade scheduled to cover approximately 30 to 40 buildings.

Network Management and System Integration
The technical selection was driven by the system's ability to integrate into existing digital management frameworks. The solution utilizes the Nokia Altiplano Access Controller, allowing network administrators to provision and manage both the fiber access network and the MoCA Access coaxial segment as a unified, end-to-end infrastructure. Furthermore, the hardware was integrated into the operator's TruVizion broadband diagnostics platform. This configuration provides engineering teams with direct visibility into MoCA status, signal performance, and standard network diagnostics, thereby streamlining maintenance and lifecycle management.

Operational and Sustainability Outcomes
By repurposing legacy coaxial cables, the deployment eliminates the need for complete building rewiring. This accelerates installation timelines and reduces capital expenditures associated with high-speed network upgrades. The approach ensures that existing multi-dwelling unit connectivity can support managed multi-gigabit broadband delivery. In addition to optimizing operational efficiency, the reuse of existing infrastructure supports resource management objectives by minimizing construction waste, reducing raw material consumption, and limiting the manufacturing demand for new cabling components.
