As mobile networks expand beyond dense urban areas, backhaul has become the defining constraint. In many markets, capacity already exists at the edge. The greater challenge lies in transporting it efficiently across long distances, fragmented spectrum, and power-limited sites.
MWC Barcelona 2026 offers a timely platform to address this reality.
Spectronite approaches backhaul differently. Rather than compensating for constraints with additional spectrum, higher power, or denser infrastructure, the focus is on extracting maximum capacity from existing spectrum and sites, fundamentally redefining backhaul economics and performance.
Why Backhaul Efficiency Now Defines Expansion
In most deployments, radio access is no longer the bottleneck. Backhaul is. Traditional microwave and millimetre wave solutions force trade-offs between distance, capacity, and power consumption. Fragmented spectrum remains underused, and scaling capacity quickly drives up cost. These limitations slow rural and remote rollout and undermine network economics.
Spectronite removes these trade-offs by maximizing what operators already hold in their spectrum and infrastructure.
Digital Carrier Aggregation Built Into the Architecture
Spectronite’s core differentiator is digital carrier aggregation across non-adjacent channels, combined with a software‑defined radio architecture. This allows up to 20x more usable backhaul capacity from fragmented spectrum compared with traditional single‑channel systems.
By aggregating channels digitally rather than relying on analogue combining, nearly all transmit power is preserved and spectrum utilisation approaches 98 percent, enabling operators to unlock multi‑gigabit backhaul capacity using existing licensed spectrum.
These capabilities support up to 5 Gbps transmission, with roadmaps toward 10 Gbps and beyond without requiring new spectrum allocations.
“Networks today must expand rapidly while keeping energy and cost under control. By fully embracing software‑defined, spectrum‑efficient backhaul, operators can deliver multi‑gigabit capacity without resorting to heavier spectrum loads or higher power. This changes the economics of rural and remote connectivity and unlocks new potential for growth.
– Jean-Philippe Fournier, CEO of Spectronite
Long‑Distance Capacity Without Proportional Power Increase
Maintaining capacity over long distances typically requires higher power, additional hops, or more complex RF planning. Spectronite’s radios operate across 6 GHz to 23 GHz with high receiver sensitivity and tight control of out‑of‑band emissions, enabling stable long‑distance links for rural, remote, and over‑water deployments.
Operators benefit from an over 80% reduction in power consumption per transported bit, making high‑capacity backhaul feasible at power‑limited and off‑grid sites.
Crucially, capacity increases do not require a linear increase in power consumption. Digital aggregation significantly reduces power loss, improving both network economics and energy efficiency.
Software‑Defined Control for Evolving Networks
Spectronite’s radios are fully software‑defined, enabling real‑time spectrum sensing, adaptive capacity allocation, and integration with modern network management systems. This allows operators to dynamically assign capacity based on spectrum availability, traffic demand, and operational policies instead of statically overprovisioning for peak demand.
Operators gain software‑defined radios that adapt in real time, responding to network conditions and evolving network demands.
“The conversations we are having with operators confirm a clear priority: cover more people with reliable capacity while reducing energy and cost burdens. Our technology gives them a practical path forward. By turning fragmented spectrum into stable, high‑throughput links, we help networks scale efficiently and sustainably.”
– Grégory Pernot, CCO of Spectronite
Built for Critical Infrastructure
Designed, developed, and manufactured in France, Spectronite’s hardware meets stringent European standards for reliability, performance, and environmental compliance. Compact hardware and software‑driven configurations reduce installation complexity, site footprint, and total cost of ownership.
By combining high throughput, ultra‑efficient spectrum use, and power savings, Spectronite redefines what wireless backhaul can achieve without overbuilding physical infrastructure.
