Microwave scatters evaluation for indoor/outdoor broadband coverage and data transmission
Bibliographic record
Abstract
This study focuses on the investigation of microwave scatter for data transmission relay to extend the signal coverage whether indoor or outdoor for non-line-of-sight (NLOS) applications. This provides an economic solution to improve broadband access to subscribers in remote places. A series of CW measurements over 29-30 GHz was conducted indoor at an intersection of two hallways in presence of a microwave scatterer such as flat surface metallic reflector. Also measurements were carried outdoor to target an office building in the campus of the CRC. Whether indoor or outdoor, Results show that microwave scatter provides better signal coverage and data throughput. Its strength depends strongly on the scatterer's type and surface. Results also indicate that, for systems operating at a short range, microwave scatter provides an alternative to LOS systems, cables or the use of retransmission systems. The measurement system involves a new evolutional method of providing phase coherence between transmitter and receiver where both transmitter and receiver are connected by means of a single-mode optical fiber cable.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
