    "body_text": "MultiPathFormer is a proposed wireless foundation model built around path-level channel tokens, an environment-retrieval component and a codebook anchored to the first arriving path. The authors report gains of as much as 59 percent in path-statistics tasks across 27 environments, along with improvements on downstream evaluations. The numbers are author-reported preprint results; they do not establish deployed-network throughput, coverage or commercial performance.",
