The article provides a description and results of pilot industrial tests that took place in 2020-2021 at the enterprise of Rosneft Oil Company - Syzran Oil Refinery. The object of testing for the first time was the Private LTE wireless data transmission technology, which was based on equipment and software from domestic manufacturers. Before the pilot tests in Syzran, Russian companies tested only private LTE networks created on the basis of foreign software and equipment. The article presents the applied digital solutions operating on the private LTE network of Rosneft Oil Company, including the development of Mobile Employee, a video data monitoring system, a video surveillance system for filming objects of any type, an automated system for monitoring and metering of electricity, a hardware and software complex for monitoring personnel based on wearable wireless search and intercom devices and others. Most of the described digital solutions are also developed by Russian companies. The pilot tests in Syzran was preceded by tests of Private LTE in the laboratory of the one of Russians concern, where a demonstration test stand was deployed. The pilot tests directly included two stages: testing of the hardware - radio equipment responsible for the operation of the Private LTE network, as well as testing of the LTE communication itself and a set of digital solutions based on it. The pilot tests allowed to come to the following conclusions: Private LTE technology will help the Rosneft’s enterprises to abandon part of the current costs or optimize them, and applied digital solutions that are part of the Private LTE ecosystem will contribute to accelerated digitalization.
