Abstract
Worldwide interoperability for microwave access (WiMAX) has been envisioned by the WiMAX forum as a single worldwide adopted standard for high-speed wireless metropolitan area networking. The term WiMAX denotes wireless metropolitan area network (WMAN) technology based on IEEE 802.16 specifications. In this chapter, we provide an overview of the salient features and most important specifications of legacy and next-generation WMANs. Fixed WiMAX The initial IEEE 802.16 WiMAX standard was established in the frequency band 10–66 GHz, providing up to 75 Mb/s line-of-sight (LOS) connections for both point-to-multipoint and mesh modes. Table 7.1 summarizes the IEEE 802.16 WiMAX standard family. PHY layer IEEE 802.16a provides non-LOS connections in the frequency band of 2–11 GHz (licensed and unlicensed). The WiMAX physical (PHY) layer supports the following four different modulation schemes: WirelessMAN-SC (single carrier), WirelessMAN-SCa (single carrier access), WirelessMAN-OFDM (orthogonal frequency division multiplexing), and WirelessMAN-OFDMA (orthogonal frequency division multiple access). WhileWirelessMAN-SC has been designed for the frequency band 10–66 GHz, the other modulation schemes can be used for the frequency band 2–11 GHz. Additionally, the WiMAX PHY layer transfers bidirectional data by means of time division duplex (TDD) or frequency division duplex (FDD). MAC layer IEEE 802.16 is a connection-oriented standard, i.e., prior to transmitting data between subscriber stations (SSs) and base station (BS) connections must be established.

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.
