SEA Data¶
The purpose of the National Advanced Spectrum and Communications Test Network (NASCTN) Citizens Broadband Radio Service (CBRS) Sharing Ecosystem Assessment (SEA) project is to provide data-driven insight into the CBRS sharing ecosystem’s effectiveness between commercial and Department of Defense (DoD) incumbent systems, and to track changes in the spectrum environment over time. CBRS is the “first of a kind” nationwide shared spectrum ecosystem in the 3550-3700 MHz band. The implementation of this project included the installation of sensor systems at selected sites on the east and the west coast of the United States, along with a control and prototyping system in Boulder, Colorado. This data provides time and frequency selective power measurements from 3530 MHz -3710 MHz from summer 2024 to summer of 2026. This data is targeted at the commercial, military and civilian stakeholders of Citizen's Broadband Radio Service (CBRS) that would benefit from in-depth real time and longitudinal analysis of a shared spectrum environment. These data were collected with sensors running the IEEE 802.15.22.3 Spectrum Characterization and Occupancy Sensing (SCOS) sensor system. In addition, the data is formatted and saved using SigMF (signal metadata format). This project was a collaboration between NIST, NTIA / ITS, NASA and MITRE.

SEA CODE¶
| Repository | Description |
|---|---|
| nasctn-sea-ingest | This repository contains sea_ingest, a Python package which can quickly and conveniently load many NASCTN SEA sensor data files. These are the outputs from SEA sensors produced after edge compute analysis, which follow the SigMF format. The sea_ingest package supports loading sensor metadata from both prototype- and production-era SEA sensors. This tool parses data products and metadata from .sigmf files and packages them into pandas or Dask DataFrame objects. From there, the data can be analyzed directly, or piped into files or databases using Dask multiprocessing hooks. |
| nasctn-sea-visualization | Tools to open, reshape and visualize data from the NASCTN CBRS SEA program. |
| nasctn-sea-modeling | This repository contains code used in the modeling for the National Advanced Spectrum and Communications Test Network (NASCTN) Sharing Ecosystem Assessment (SEA) project. It runs dynamic protection area (DPA) move list algorithm and computes aggregate emission at protection points and sensor locations in the Citizens Broadband Radio Service (CBRS) band. Some of the scripts were derived from the WInnForum's reference implementation of the Spectrum Access System (SAS) test harness. |
| nasctn-sea-rf-mapping | This repository contains code used in the modeling for the National Advanced Spectrum and Communications Test Network (NASCTN) Sharing Ecosystem Assessment (SEA) project. It computes and visualizes each NASCTN sensor's RF horizon mapping. Part of the code was derived from the WInnForum's approach and implementation of the Environmental Sensing Capability (ESC) sensor's whisper zone. |
| nasctn-sea-dpa-neighborhood | This repository contains code and sample data used in the modeling for the National Advanced Spectrum and Communications Test Network (NASCTN) Sharing Ecosystem Assessment (SEA) project. It calculates neighborhood distances for selected coastal Dynamic Protection Areas (DPAs) used in the 3.5 GHz Citizens Broadband Radio Service (CBRS) band to protect the federal incumbent systems. The code is a modification of the DPA Neighborhood Calculation code, which was implemented by the National Telecommunications and Information Administration (NTIA) Office of Spectrum Management (OSM). The code can support both OSM's simulated census centroid deployment and Full Activity Dump (FAD) of CBSD grants provided by the Spectrum Access System (SAS) operators (if available). |
| scos-sensor | SCOS Sensor is a work-in-progress reference implementation of the IEEE 802.15.22.3 Spectrum Characterization and Occupancy Sensing (SCOS) sensor developed by NTIA/ITS. SCOS Sensor defines a RESTful application programming interface (API), that allows authorized users to discover capabilities, schedule actions, and acquire resultant data. |
| sigmf-ns-ntia | This Signal Metadata Format SigMF namespace extension describes the National Telecommunications and Information Administration (NTIA)'s open data format for recorded signal datasets. |
