FieldState measurement protocol
A protocol for documenting a physical field state and testing a pre-specified biological endpoint. The protocol tests whether a specific field feature produces a measurable biological response under controlled conditions.
BERM v17 requires more than a national technology proxy or one broadband level. A useful experiment documents the measured field components, calibration, geometry, timing and provenance that could distinguish competing physical hypotheses.
The purpose of this protocol is to make the physical measurement and the biological experiment independently auditable. A physical signature, if observed, is a prerequisite for a mechanism test — not evidence of harm or a TFR coefficient.
01
1. Pre-specify the question and endpoint
State the field feature, biological system, primary endpoint, exposure contrast, timing, analysis and exclusion rules before collection. Register a null-compatible hypothesis as well as the proposed directional hypothesis.
Choose an endpoint close to the tested link: for example a calibrated physical PSD feature, a cellular redox readout, a tight-junction protein, a sperm-function measure or a reproductive hormone. Do not use national TFR as the direct endpoint of a laboratory exposure experiment.

2. Acquire a documented physical FieldState
Record calibrated instruments, antenna or probe response, band selection, dynamic range, sampling chain, location, orientation, device posture, time zone, clock synchronisation and raw-data checksums. Measure the local static magnetic background B₀ vector where it is relevant to the hypothesis.
Keep ambient and personal-source conditions distinct. If the physical question concerns an organ, describe the transfer model or phantom/position measurement; a room measurement is not automatically an organ field estimate.
Experimental setup illustration
What actually differs between two experiments?
Compare two example setups. Choose one difference and see what needs to be recorded around the sample.
Coil pair and sample stage
Coil pair and sample stage
The same device setting can meet differently oriented samples. Here the sample's reference axis rotates while the coils and background direction stay fixed.
Record for the comparisonThe sample reference axis, source field vector and local B₀ vector in the same coordinate system.
How to read the figure and document the measurement
A directional sample is used as an example. Sample posture, probe orientation and the biologically relevant receiving direction are different quantities. Rotation alone does not specify the sign or size of a response.
In both setups. Record the sample, life stage and handling, the source's actual waveform and field components, the local B₀ vector, probe calibration, measurement time and temperature. Blinding, sham conditions and the biological endpoint belong in the actual experiment's protocol.
This is an example setup illustration. It does not reproduce a named study or display a biological result. Comparing a conditional BERM response also requires a specified receiver and endpoint; missing information is not evidence of a hidden effect.
Field components
Capture the relevant electric/magnetic components and source band(s); retain calibration and uncertainty, not just a single summary level.
Time structure
Create a time-stamped band-power or field-amplitude series, then estimate envelope/beat PSD after the carrier or band has been validly acquired.
Context
Record vector orientation, phase/coherence where measurable, circadian time, source configuration and environmental conditions that can alter the apparatus.

3. Treat eDRX and R42 correctly
eDRX is a user-equipment discontinuous-reception/paging scheduling mechanism. It is not, by itself, a known cellular downlink RF waveform or an ambient-field signature. An eDRX timer may be logged as network/device metadata, but it must not be substituted for a measured downlink envelope PSD.
Zandieh et al. (2025) reported frequency-dependent mitochondrial/ROS behaviour in cancer-cell experiments under ELF magnetic-field conditions (0.01–5 Hz; up to 100 mT, including 0.02 and 0.04 Hz conditions). That result motivates an exploratory PSD test; it does not establish RF network modulation, eDRX spectral lines or reproductive effects.

4. Run a controlled biological arm
Use blinded allocation where possible, a sham condition and a thermal/airflow/handling control that is matched to the active apparatus. Instrument the exposure chamber during every run rather than assuming that its setpoint describes the delivered condition.
Vary one pre-specified FieldState feature at a time when feasible: vector angle, static background, field amplitude, timing/PSD feature or circadian phase. Include positive controls only when their biological interpretation is appropriate; do not treat a rescue as proof of an upstream field mechanism.

5. Analyse and report
Publish raw or access-controlled raw field data, processing code, calibration files, biological data, exclusions, adverse events and null results. Report effect estimates with uncertainty and compare the active and sham FieldStates, not only nominal device settings.
Classify the result by data readiness: a technology-timing proxy for national series, partial FieldState data when inputs are missing, and measurement-ready FieldState when calibration, B₀, transfer, PSD, circadian context, phase/coherence and provenance are documented. Measurement-ready data still require an endpoint-specific test.
Interpretation boundary
This protocol can test a physical-to-biological link. It cannot by itself identify a population effect, separate all environmental causes or justify a personal health recommendation. Any later ASFR/TFR analysis must join measured FieldState and endpoint data with demographic demand, tempo and ART terms.
