In such multi-band systems, reliable information obtained from the sub-6 GHz band can be exploited to support communication at mmWave frequencies. To ensure that both systems experience similar multi-path propagation effects, the sub-6GHz and mmWave antenna arrays have to be colocated and precisely aligned. However, such a configuration may adversely alter the radiation characteristics of the array"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The results demonstrate that the influence of the mmWave structure on the sub-6 GHz performance is minor, indicating that co-located configurations are feasible with negligible degradation.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the chosen simulation models and measurement setups accurately represent real-world multi-path propagation and radiation characteristics without significant unaccounted factors such as mutual coupling details or environmental variations.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Placing a mmWave antenna structure in front of a sub-6 GHz array causes only minor changes to the sub-6 GHz radiation pattern, making co-located configurations feasible with negligible degradation.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Placing a mmWave antenna structure in front of a sub-6 GHz array causes only minor degradation to sub-6 performance.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"f8ed6c96facfc130d65f6e26ef6fb9ae25b7f8f1cebd189c737dbaf465b08c85"},"source":{"id":"2604.02813","kind":"arxiv","version":2},"verdict":{"id":"f30ca6d0-3556-4eb2-956f-5b5ce694d1e7","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-13T18:31:00.410074Z","strongest_claim":"The results demonstrate that the influence of the mmWave structure on the sub-6 GHz performance is minor, indicating that co-located configurations are feasible with negligible degradation.","one_line_summary":"Placing a mmWave antenna structure in front of a sub-6 GHz array causes only minor changes to the sub-6 GHz radiation pattern, making co-located configurations feasible with negligible degradation.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the chosen simulation models and measurement setups accurately represent real-world multi-path propagation and radiation characteristics without significant unaccounted factors such as mutual coupling details or environmental variations.","pith_extraction_headline":"Placing a mmWave antenna structure in front of a sub-6 GHz array causes only minor degradation to sub-6 performance."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.02813/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":2,"snapshot_sha256":"be97c551c63e3f4d414567347c85497b28c5050e3756198ff08142f6a8a724c8"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
