The frequency spectrum is a scarce resource, and is owned and regulated by the state to ensure its efficient and fair utilization. All over the world, a large number of Mobile Network Operators (MNOs) are already involved in either active or passive Radio Access Network (RAN) sharing to maximize cost savings. The aim of this article is to challenge the ownership of individual operator’s infrastructure and present technical arguments for One Radio Access Network (OneRAN) approach for deploying a cellular network. The enormous increase in data traffic and regulatory requirements concerning public safety communications provide the basis for migrating to OneRAN infrastructure. The OneRAN approach provides an opportunity to gain technological benefits and helps in meeting the requirements of critical communication. OneRAN targets to maximize the savings on capital and operational expenses. The main focus of this work is outdoor wide-area coverage i.e., outdoor users in rural areas and on highways, as it is assumed that indoor service provision in the future requires a dedicated indoor solution. For the research work of this article, a measurement campaign was launched and different Key Performance Indicators(KPIs) of Long Term Evolution(LTE) technology for three commercial MNOs of Finland were measured over a 52 km highway from Iittala to Tampere city. The acquired results highlight the gain of OneRAN infrastructure as it enhanced the user quality of experience i.e., user throughput, especially of the critical cell border users, and improved the overall system performance economically. Finally, supportive arguments are presented for having a OneRAN infrastructure specifically over the highways.

频谱是稀缺资源，由国家拥有和监管，以确保其有效和公平的利用。在世界各地，大量移动网络运营商 (MNO) 已经参与了主动或被动无线接入网络 (RAN) 共享，以最大限度地节省成本。本文的目的是挑战单个运营商基础设施的所有权，并提出用于部署蜂窝网络的单一无线电接入网络 (OneRAN) 方法的技术论据。数据流量的巨大增长和有关公共安全通信的监管要求为迁移到 OneRAN 基础设施奠定了基础。OneRAN 方法提供了获得技术优势的机会，并有助于满足关键通信的要求。OneRAN 的目标是最大限度地节省资本和运营费用。这项工作的主要重点是室外广域覆盖，即农村地区和高速公路上的室外用户，因为假设未来的室内服务提供需要专用的室内解决方案。在本文的研究工作中，发起了一项测量活动，并在从伊塔拉到坦佩雷市的 52 公里高速公路上测量了芬兰三个商业 MNO 的长期演进 (LTE) 技术的不同关键性能指标 (KPI)。获得的结果突出了 OneRAN 基础设施的优势，因为它提高了用户体验质量，即用户吞吐量，特别是关键小区边界用户的吞吐量，并经济地提高了整体系统性能。最后，
