Capabilities

Where the engineering depth lives.

Wavelet Solutions operates across four domains. The breadth is deliberate — hard problems tend to sit between specialties, and an engineering practice without depth in adjacent areas misses what those problems actually require. What follows is a candid description of where we work and what we bring to each domain.

Domain I of IV
I
SCADA / ICS / OT

Industrial & infrastructure.

Modernization and hardening of operational technology environments where uptime is non-negotiable and change management is as important as engineering skill. Utilities, manufacturing, water and wastewater, oil and gas. The intersection of legacy hardware, critical uptime, and modern networking is where engineering judgment earns its keep.

Four-tier OT network topology: enterprise, DMZ, control and field, with a firewall and broker between IT and OT, redundant master stations, and five field devices on a preserved serial bus.
Fig. 1 A phased migration in one picture. The field bus and the RTUs on it stay exactly where they are — including the legacy drop nobody wants to touch, dashed at right. Everything that changes sits above the segmentation boundary, which is why the plant keeps running while the work happens.

SCADA modernization & integration.

Upgrading legacy SCADA and industrial control systems to modern IP-based architectures without disrupting operations. Preserving what works while adding the monitoring, security, and maintainability aging systems lack — with zero-downtime migration planning from the start.

What this includes
  • IP-based network architecture design and implementation
  • Legacy protocol integration: Modbus RTU/TCP, DNP3, proprietary serial
  • Zero-downtime migration planning and phased rollouts
  • Modern HMI and SCADA visualization platforms
  • Complete system documentation and operator training

Industrial cybersecurity.

Security hardening for OT environments done by an engineer who understands that a patch window does not exist, downtime is unacceptable, and the wrong change can take a plant offline. The threat model and the operational reality have to be reconciled, not chosen between.

What this includes
  • NERC CIP compliance assessment and implementation
  • OT network architecture and IT/OT segmentation
  • ICS security hardening and access controls
  • Vulnerability assessment and remediation planning
  • Secure remote access and VPN design
Domain II of IV
II
Defense / Aerospace / Space

Defense & government.

Satellite communications, military waveforms, RF systems, and complex program leadership — backed by substantial experience across defense and aerospace programs. The standard applied in defense, where engineering failure means mission failure, transfers cleanly to commercial work.

Measured power spectral density plotted in dBc against a stepped emission mask, with the signal sitting inside the mask across the full offset range.
Fig. 2 Measured spectrum against a stepped emission mask. Compliance is not a checkbox at the end of a program; it is a constraint that shapes the waveform, the filtering and the amplifier line-up from the first architecture decision onward.

RF & signal processing.

Waveform design, signal detection, satellite link analysis, and software-defined radio development — bridging the gap between theoretical signal work and fielded hardware. The work that lives between physics and protocol.

What this includes
  • Waveform design and analysis: OFDM, DSSS, CPM, FSK
  • Signal detection and classification algorithms
  • Satellite link budget and system analysis
  • Proof-of-concept radio links: sub-GHz, 915 MHz ISM, proprietary and mesh
  • SDR development and integration
  • NTIA / FCC spectral compliance and RF interference mitigation

Technical program leadership.

Leading complex programs from concept through deployment — technical teams, vendor relationships, integration challenges, evolving requirements. The difference between a technical program manager and a regular one is the ability to get into the work when something is going wrong. The practice does both.

What this includes
  • Program planning, milestone definition, and risk management
  • Technical team leadership and vendor coordination
  • Hands-on integration oversight and troubleshooting
  • Stakeholder communication and reporting
  • Quality assurance and acceptance testing
Domain III of IV
III
Software / Embedded / Firmware

Software & technology.

Greenfield development, rescue of projects that have gone off the rails, and embedded systems work from bare-metal firmware through cloud-connected platforms. Where the discipline of defense-grade work meets the pragmatics of commercial software delivery.

Fig. 3 An eye diagram is the fastest honest answer to “is the link healthy?” The opening is margin, the blur is jitter, and the marked instant is the one moment the whole link is judged at. Firmware that ignores where that instant falls is firmware that works on the bench and fails in the field.

Software development & rescue.

Purpose-built software across domains, and honest recovery of projects that have gone off the rails. Greenfield systems built right from the start or codebases that need a clear path forward — the approach is the same: requirements first, architecture before code, maintainability as a non-negotiable.

What this includes
  • Multi-language development: C, C++, Rust, Python, Go
  • Real-time data acquisition and processing platforms
  • Protocol conversion, APIs, and system integration
  • Legacy codebase assessment and rescue plans
  • Cross-platform applications: Linux, Windows, embedded

Embedded systems & firmware.

From bare-metal microcontrollers to RTOS platforms — proof of concept, development, and rescue. A low-power sensor that has to run for years, a link that has to close, a controller that has to exist by the demo date: built on the least part that meets the spec, measured, and handed over with a design that ships. Lost source code and unreachable original developers are the other half of the practice: reverse-engineered, recreated, modernized, with full documentation when the work is done.

What this includes
  • Proof-of-concept builds: low-power sensing, custom radio, battery-life validation
  • Bare-metal and RTOS firmware development
  • Legacy firmware recovery from binaries
  • Protocol implementation: SPI, I2C, UART, CAN
  • Modern connectivity additions: USB, WiFi, BLE, cloud
  • Signal acquisition and real-time processing

Systems Engineering / Foundations

Engineering foundations.

The work that makes every other engagement stick — rigorous requirements, defensible architecture, root cause analysis, and a team that understands the system when the engagement ends. Most projects fail not in execution but in definition; this is where that failure gets prevented.

Requirements decomposition from a single system-level operational need through functional, performance, interface and environmental branches, down to four acceptance criteria, one of which is marked unverifiable.
Fig. 4 Requirements decomposition, carried down until every branch terminates in something measurable. The dashed node at right is the whole value of doing this: one criterion cannot be verified as written, and it is far cheaper to find that here than at acceptance testing.

Systems architecture & requirements.

Most projects fail not in execution but in definition. Rigorous requirements — functional and non-functional — and a defensible architecture before a line of code is written. This is where expensive rework is prevented.

What this includes
  • Functional and non-functional requirements capture
  • System architecture design and validation
  • Interface definitions and protocol specifications
  • Risk assessment and mitigation strategies
  • Validation criteria and acceptance test plans

System troubleshooting & rescue.

Root cause analysis and lasting fixes for problems that have been around too long — RF interference, timing failures, protocol mismatches, mysterious integration gaps. Schematics read, signals analyzed, failures traced to actual sources. Every engagement ends with a client who understands exactly what happened and why.

What this includes
  • Root cause analysis and failure diagnosis
  • Signal analysis and protocol debugging
  • Communication network troubleshooting
  • Integration problem resolution and optimization
  • Emergency response and critical fixes

Whether the scope is clear or you haven’t fully characterized it yet, the conversation starts the same way: tell us what you’re trying to accomplish and what’s standing in the way. The rest follows from there.
