Abstract
The WiMedia Ultra-Wide Band (UWB) specifications include physical layer and distributed Medium Access Control (MAC) layer. Physical layer offers a range of coded data rates from 53.3 Mb/s to 480 Mb/s. WiMedia MAC consists of Beacon period (BP), Distributed Reservation Protocol (DRP) and Prioritized Contention Access (PCA). DRP allows access to the medium through reservation, while PCA provides access to the bandwidth not utilized by DRP through contention. In this paper, we present an integrated performance analysis of the DRP and PCA schemes which includes the multi-rate transmission at the physical layer. We assume DRP traffic with several classes and PCA traffic with multi-priority levels. We determine the call blocking probabilities for DRP classes of traffic, throughput and mean packet delay for PCA traffic and bandwidth utilization of the system. The numerical results show that under heavy traffic throughput of low priority traffic drops and its delay increases sharply.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
