Wireless Technology Advancements
Inácio’s Research Focus: Signals
Inácio’s research focuses on signals that most people never notice, such as radio waves moving between devices. That’s 24 hours a day, 7 days a week. Inácio is working to improve this process, making it faster and more efficient.
The Netherlands Organization for Applied Scientific Research (TNO) is a leading research institute in the Netherlands. Inácio is part of the Wireless Communication department, where she works alongside 120 researchers.
Her work zeroes in on the behavior of electromagnetic signals in congested environments—places where dozens of devices transmit data simultaneously. Urban centers, smart homes, and industrial IoT setups generate massive signal overlap. Inácio’s team models interference patterns using stochastic methods and machine learning-driven prediction tools. Their models don’t just detect noise—they anticipate it. That’s a shift from reactive filtering to proactive signal shaping.
One of her projects involves optimizing frequency reuse in dense device networks. Instead of assigning fixed bands, the system dynamically reallocates slices based on real-time demand and interference risk. This isn’t theoretical—early testbeds in The Hague’s municipal IoT network have shown a 38% drop in packet loss during peak usage. The results suggest that adaptive signal management can significantly reduce congestion without requiring new spectrum allocations.
Radio Waves and Devices
Radio waves are the invisible signals that move between devices. Inácio’s work aims to improve this process, making it faster and more efficient. That’s 120 researchers at TNO working on similar projects.
The physical layer of wireless communication has remained a bottleneck even as higher-level protocols evolved. While 5G introduced millimeter wave bands and massive MIMO, the underlying challenge of spectral efficiency persists. Inácio’s work targets this layer, where bits become waves and back again. She’s refining modulation schemes that pack more data into the same bandwidth without increasing power output. One approach involves phase-coded waveforms that resist multipath distortion—common in indoor and urban canyon environments.
Her team has also developed a prototype transceiver that uses dual-polarization signaling to double effective channel capacity in short-range links. The device doesn’t require new infrastructure; it’s compatible with existing 5G NR and Wi-Fi 6E standards. Field trials with a Dutch logistics company showed a 42% improvement in warehouse sensor network responsiveness. That kind of gain matters when autonomous forklifts rely on split-second coordination.
Inácio isn’t just solving engineering puzzles—she’s rethinking assumptions. For years, wireless systems treated interference as noise to be minimized. Her research treats it as data. Every reflection, every delayed signal, carries information about the environment. By decoding these artifacts, her systems can simultaneously improve communication and perform passive sensing—detecting movement or structural changes without active radar.
TNO’s Female Researchers
30% of Researchers are Women
TNO has 30% female researchers, with Inácio as one of them. That’s 36 researchers, including Inácio, who are working on innovative wireless technologies.
The number reflects a slow but real shift in Dutch STEM research culture. In 2010, women made up just 18% of TNO’s technical staff. The jump to 30% by 2026 wasn’t accidental. It followed targeted recruitment, flexible research tracks, and internal mentorship loops. The Wireless Communication department, where Inácio works, reached gender parity in junior researcher roles by 2024—though leadership roles still skew male.
Inácio’s presence isn’t symbolic. She leads a sub-team of eight researchers focused on physical layer innovation. Two of her direct reports are women, both early-career engineers who cite her mentorship as a reason they stayed in the field after graduate school. One joined after completing a PhD at TU Delft, where she felt isolated in a lab of 22 men. At TNO, she found a research environment where technical rigor and collaborative culture coexist.
The 30% figure is often cited as a tipping point for influence in group dynamics. At TNO, female researchers have pushed for broader consideration of use-case diversity—asking how systems perform not just in ideal conditions, but in homes with thick walls, in rural areas with spotty coverage, or in multilingual environments where voice-controlled devices struggle. Inácio’s team built a test chamber that simulates signal degradation across different building materials, a setup now used across departments.
Impact of Inácio’s Work
Revolutionizing Wireless Communication
Inácio’s work could revolutionize wireless communication. That’s 10 years of research, and her team is making progress. Inácio’s work could enable faster and more efficient wireless communication in the future.
The practical impact isn’t just about speed. It’s about reliability and scalability. As cities add more connected devices—traffic sensors, air quality monitors, emergency alerts—the existing wireless infrastructure creaks. Inácio’s dynamic allocation system has been trialed in a pilot with Rotterdam’s public transit authority. Buses equipped with her team’s firmware showed 55% fewer connectivity dropouts during tunnel passages, a known pain point for passenger information systems.
Another outcome is energy savings. When devices transmit more efficiently, they spend less time broadcasting. In battery-powered sensors, that translates to longer lifespans. A forestry monitoring project in Limburg deployed 200 sensors using Inácio’s low-power waveform design. After 18 months, 94% were still operational—compared to 68% in a control group using standard protocols. For remote deployments, that’s the difference between monthly maintenance and years-long autonomy.
The work also has implications for spectrum policy. Regulators like the Agentschap Telecom monitor how efficiently bands are used. Inácio’s data on real-world spectral efficiency has been cited in Dutch government briefings on 6G readiness. If adaptive systems can deliver 2x the throughput in existing bands, the pressure to auction new spectrum may ease—delaying costly rollouts and reducing barriers for smaller providers.

In pilot tests, her team’s firmware reduced video jitter by 60% in low-signal areas—making remote diagnostics more viable without requiring new towers or fiber lines.
For a hardware engineer at a smart home company, her dynamic frequency management offers a way to scale device counts without degrading performance. Today, homes with 30+ connected devices often suffer from stuttering automation. Systems using Inácio’s channel optimization maintain responsiveness up to 50 devices in trials. That’s room for growth as homes add more sensors, appliances, and security tools.
For a city planner overseeing a smart infrastructure rollout, her energy-efficient protocols extend the lifespan of embedded sensors. Parking occupancy detectors, flood monitors, and structural health systems can run for years on a single battery. That slashes maintenance costs and makes long-term monitoring projects financially sustainable. In a test in Utrecht, Inácio’s low-power mesh network kept 120 sensors online for 22 months with zero battery replacements.

Key Questions Remaining
Can Inácio’s dynamic allocation system scale beyond city-level pilots? The Hague trial involved 3,000 devices. A national rollout could mean millions. The computational load of real-time optimization grows exponentially with device count. Her team is exploring distributed AI models where devices share prediction workloads—each node contributing processing power to forecast interference patterns. Early simulations suggest it’s feasible, but real-world coordination remains untested at that scale.
How will legacy devices interact with next-gen networks? Not every device will adopt Inácio’s protocols overnight. Mixed environments—where some devices use adaptive signaling and others broadcast blindly—could create new forms of interference. Her team is developing backward-compatible gateways that act as translators, smoothing transitions. They’ve tested one with a mix of Wi-Fi 4, 5, and 6 devices, achieving 80% of the efficiency seen in all-adaptive networks.
Who controls the intelligence layer? If signal optimization becomes AI-driven, the entity with the best models could dominate wireless performance. That raises concerns about centralization and access. Inácio advocates for open standards and shared training data, arguing that signal intelligence should be a public resource. TNO has published two core algorithms under a research-use license, but commercial adoption depends on industry buy-in. The next 18 months will show whether vendors embrace openness or lock down proprietary versions.
