It provides cloud-native, flexible, and disaggregated architecture providing scalability and streamlining network management through standardized operations [1].<br \/>\nAs part of Rogers\u2019 wireless network evolution strategy, Rogers has been collaborating with our partner vendor on the Open RAN technology evolution based on a Cloud RAN solution. Rogers Communications successfully trialed 5G Cloud RAN technology based on separated Centralized Unit (CU) and Distributed Unit (DU) architecture over a commercial network at a live event in Canada in 2024 [2, 3]. In February 2025, another milestone was achieved with the 5G Cloud RAN successful trial based on a combined CU and DU architecture in a live network followed by the trial of Next Generation Open Lower Layer Split (NG-OLLS) interface (i.e. Open Fronthaul) in April 2025.<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":true,"footnotes":""},"categories":[14,7],"tags":[],"class_list":["post-40316","post","type-post","status-publish","format-standard","hentry","category-2020s","category-all-decades"],"acf":[],"_links":{"self":[{"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=\/wp\/v2\/posts\/40316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=40316"}],"version-history":[{"count":0,"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=\/wp\/v2\/posts\/40316\/revisions"}],"wp:attachment":[{"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=40316"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=40316"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nctatechnicalpapers.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=40316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
