Abstract
This paper is a systems engineering overview of a state-of-art packet switched radio data system-the Mobitex system. RAM Mobile Data operates Mobitex systems in the US and the UK. Mobitex systems are also in operation in Scandinavia and Canada. The system architecture is 'open', which allows any company to enter the wireless data business by providing radio modems and/or application software conforming to the Mobitex interface specification. This paper first outlines the Mobitex network architecture, network protocol, RF system design and the Mobitex 'open' air interface. Finally, the spectral efficiency and response time for transmission of short messages using a wireless packet data network and present day analog cellular systems are compared. It is concluded that a wireless packet data network is superior to analog cellular systems both in terms of spectral efficiency and response time for short data messages.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
