Based on the massive multiple-input multi-output (MIMO) antennas and the millimeter wavecommunication technologies, the 5G ultra-dense cellular network is proposed to deploy in overall cellular scenarios. Moreover, a distribution network architecture is presented for 5G ultra-dense cellular networks. Furthermore, the backhaul network capacity and the backhaul energy efficiency of ultra-dense cellular networks are investigated t","authors_text":"Cheng-Xiang Wang, Guoqiang Mao, Song Tu, Tao Han, Xiaohu Ge","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NI","submitted_at":"2015-12-10T06:11:22Z","title":"5G Ultra-Dense Cellular Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1512.03143","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":"sha256:344f48fc80007a8f1b830fd75dbc057007aa9dda205a141b6841a2092029c89a","target":"record","created_at":"2026-05-18T01:24:37Z","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":"6916021941cf0a78600d8177c2b777a5ade480dd61b905aefd237ebf51e5a548","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NI","submitted_at":"2015-12-10T06:11:22Z","title_canon_sha256":"0cdbc8d7bc444a3617afc28fb1b5531fb129c5eb539f43b6fd17ff3f4413f0f8"},"schema_version":"1.0","source":{"id":"1512.03143","kind":"arxiv","version":1}},"canonical_sha256":"b85c9cb043859ad2b64edb2cd9c1bcf8bbc1a4b6216636ba934afa591510652f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b85c9cb043859ad2b64edb2cd9c1bcf8bbc1a4b6216636ba934afa591510652f","first_computed_at":"2026-05-18T01:24:37.809048Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:24:37.809048Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MdiUVoyxQnwCNGQWDJSxwGwOpnBUpRhfDpbkrhYKkvqt/9eZhCYPjPjwkUr/JenTKNs+DzT5cCLxtDSz7ABNDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:24:37.809456Z","signed_message":"canonical_sha256_bytes"},"source_id":"1512.03143","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:344f48fc80007a8f1b830fd75dbc057007aa9dda205a141b6841a2092029c89a","sha256:d8709e3b727feadc9b4b4ddcd675793aae1a0c014a010d9eefc8d220be02afde"],"state_sha256":"5db39676e701e269d32752c674a90ce9082681e5b064ada19a975265f03944ce"}
