# OpenCare5G: O-RAN in Private Network for Digital Health Applications
## 1 Introduction
Then InovaHC professionals developed a partnership with the diverse ecosystem of different actors among technology, telecommunications, government, universities and financial institutions. Called the OpenCare5G Project [4], it is a highly innovative initiative to study and test healthcare applications in the construction of the first 5G private network. The Open Radio Access Network (O-RAN) utilizes the O-RAN 5G concept [3; 5; 6; 7; 8; 9; 10; 11; 12] to transport health data and to help in the analysis of medical exams by health professionals using local and remote hospital portable devices and equipment. With this implementation, health professionals will be able to provide care in the middle of the rain forest using this equipment or others connected to the 5G private network safely, and carry out immediate diagnoses with their peers at HCFMUSP in Sao Paulo. The project has been coordinated by Deloitte and implemented by Airspan, Escola Politecnica da USP (EPUSP the School of Engineering--University of Sao Paulo), Itau Bank, Siemens Healthineers, Telecom Infra Project (TIP), Brazilian Agency for Industrial Development (ABDI), Inter-American Development Bank (IDB) and NEC, responsible for the integration of the O-RAN 5G network [4]. The Itau Bank, the first bank in Brazil to use O-RAN to provide a 5G connection to its network, will provide its expertise in technology, which will make it possible to carry out pilot projects. Bank experts will explore the possibilities of an innovative system in a joint learning process. An important point is that in the project, a 5G Core Network (5 GCN) will be used at Itau Bank (with Cisco, Dell and HP equipment), using the infrastructure of its datacenter, located in the Ipiranga neighborhood, 9 km from HCFMUSP with a LAN-to-LAN fiber optic connection provided by the local telecom company. The use of a 5G private network aimed at the \"freedom\" to make the bank's indoor network, without depending, in principle, on incumbent telecom companies. Itau Bank has 6000 datacenters, since each branch is considered one of these centers. That is, there is the potential to have 6000 agencies connected to the private O-RAN network throughout the country. Field tests will be carried out with \"real use cases\" of data received and sent from exams, images, and voice to evaluate the data-transmission capacity of 5G connectivity, the response time and the feasibility of performing remote exams using the higher speed and lower latency than the 5G and Beyond 5G (B5G) private networks could offer [13]. The project proof of concept (PoC) will initially focus on the first phase to perform local and remote ultrasound scans, later extending to tests of CT images that will be sent to the cloud, in which there will be processing at the edge through machine learning and AI, collaborating to improve the patient's journey and provide more access to health services, since the analysis of diagnosis can currently take days. The remainder of this paper is organized as follows: Section 2 contextualizes the related work; Section 3 presents the proposed solution framework; Section 4 describes the scenario, the methodology and PoCs used in the experiments, and reports and discusses the results. Finally, Section 5 concludes the work.
