This paper addresses the fact that small-scale changes in the position and orientation of the antenna of each RF sensor can dramatically affect imaging and localization performance of an RTI system. However, the best placement for a sensor is unknown at the time of deployment. Improving performance in a deployed RTI system requires the deployer to iteratively \"gu","authors_text":"Anh Luong, Maurizio Bocca, Neal Patwari, Thomas Schmid","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NI","submitted_at":"2013-12-19T11:05:58Z","title":"Dial It In: Rotating RF Sensors to Enhance Radio Tomography"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1312.5480","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:a512c92cf867bd030db018e7a76f724167a4af1a14fd204d300d9abc8fb7a286","target":"record","created_at":"2026-05-18T03:04:14Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"fdbdd7ab06f9bfc126d742a495b16b0d794b4ea15a64ccd1cef0c9837f763832","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NI","submitted_at":"2013-12-19T11:05:58Z","title_canon_sha256":"c0bcf2250434850fb1d72f7c92b5ceaa03a54c8d16f800b23f6711e43a45e94f"},"schema_version":"1.0","source":{"id":"1312.5480","kind":"arxiv","version":1}},"canonical_sha256":"e586be71e756bc27568aa7c9d7a3d203215244e13071657c084e38324d09e503","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e586be71e756bc27568aa7c9d7a3d203215244e13071657c084e38324d09e503","first_computed_at":"2026-05-18T03:04:14.687058Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:04:14.687058Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"We1Nc2cHzY2nDaKojn3gvtbR4oDS3dAa0ybFIVyXcDX0crzmH/TjlvTOAWthhexq6lRHABDrOS/d57/tyn/pCw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:04:14.687512Z","signed_message":"canonical_sha256_bytes"},"source_id":"1312.5480","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a512c92cf867bd030db018e7a76f724167a4af1a14fd204d300d9abc8fb7a286","sha256:e003d7a2e985daea6e077dc91a55adbcf727370ae8501873f84d40380da8b7f6"],"state_sha256":"4ef5ee7a760408daccac7f97cb5f647e9bb6cdc59b8d0cc2bf5dea4fc22c14f7"}
