SESMA is a complete spectrum management platform for national regulators and event frequency coordinators. Licensing, real-time monitoring, interference analysis, field inspections, complaints and long-term planning — the full lifecycle, from a single web interface.
Explore at resonixtech.com →Provide specialized software for the people who actually run networks and spectrum. For regulators that means one platform that carries a frequency assignment from application to licence, watches the band it was granted in, and can explain every decision years later. Our commitment is to eliminate administrative complexity, enhance officer efficiency, and ensure that every tool delivered is not a generic solution, but a precise fit for the authority we serve.
Conventional spectrum systems are records of decisions. They store what was assigned, to whom and when — and depend entirely on what an officer chose to type in. SESMA is built on a different premise: a regulator's authoritative picture of its spectrum must be continuously reconciled against what is actually being radiated. The administrative record and live measurement are held in one platform, and every function of consequence operates across both.
SESMA is not a licensing database with a monitoring viewer attached — it is a single spectrum operations platform.
Dispatcher, frequency officer and manager pipeline with inline clarification threads. On approval the system allocates the licence number, generates a QR validation token and emails the applicant — new issuance, renewal and variation handled identically.
Live traces from many receivers at once, with waterfall display, observation markers and every issued licence painted onto the band. Click a highlighted signal to open the licence record behind it.
Frequency availability with duplex pairs and every clashing licence ranked by distance. Full point-to-point microwave analysis with ranked aggressor tree, cross-polar handling and I/N and C/I per link side.
Continuous detection groups contiguous bins into channels and estimates occupied bandwidth to ITU-R 99%. An embedded neural network identifies modulation across 11 schemes with live confidence scores.
Auto-numbered compliance visits with GPS breadcrumb tracks, geotagged evidence and sweep captures — offline-safe and reconciled on reconnect. SLA-tracked interference complaints escalate to a site visit in one click.
Terrain profiles with Fresnel clearance, ITU-R P.530 link availability, Deygout diffraction and ITM Longley-Rice coverage rendering — computed against the parameters of real licensed sites.
Paged applications queue with live workload badges, three-role approval pipeline, two-way clarification threads and atomic licence issuance with public QR verification. Every status transition, field edit and approval is journalled with actor and timestamp — including before-and-after values for every technical parameter.
Server-side searchable catalogue with health counters, frequency-range windows, map radius and polygon filters, and CSV export. Applicants self-register, build applications through a guided wizard validated against the national frequency plan, and track their own holdings without calling the licensing desk.
Availability verdicts per channel with clashing licences ranked by distance, distance sweep with congestion heat-map, and a full microwave interference engine covering inbound and outbound impact. Analysis snapshots freeze the officer's exact interference landscape onto the file so a decision stays reviewable years later.
Multi-receiver live view, waterfall with three-state licence overlay, per-frequency alarm engine with CSV bulk import, and live I/Q streaming with in-browser demodulation over WebRTC. Recordings carry GPS bounding box and operator attribution for chain of custody, and stream progressively on slow links.
Missions aligned to ITU-R SM.1880 measurement types run unattended across the station fleet, pulling licensed frequencies in bulk and warning where a device's range doesn't cover the plan. Background missions yield the receiver to interactive users automatically, and signals matching no licence holder are flagged as unauthorised use.
Formal inspection lifecycle with structured compliance verdicts, categorised evidence with EXIF auto-metadata, live GPS tracks and on-site contact registers. Complaints arrive structured and SLA-tracked, with a public thread, a private investigation thread, and one-click escalation to a pre-seeded site visit.
Terrain cross-sections, link budgets with annual availability estimates, multi-edge diffraction and queued coverage simulation, all delivered as a formatted engineering report. Geo-located 3D venue scenes place antennas and cameras with visible beam cones, signal heatmaps and live target overlays.
Stations self-enrol from a single installer, discover their receivers and GPS automatically, and hold individually revocable credentials rotatable with a grace window. Administrators get live platform status, session inspection, filterable audit logs, MFA policy control and editable numbering prefixes and reference data.
