China Unicom is transforming its traditional network operations from manual methods and towards a greater use of automation, AI and big data-based analytics. As part of this transformation, China Unicom wanted to avoid the time consuming and costly manual testing of wireless networks. To meet the CSP’s needs, Nokia used its AI expertise to build an AI-driven Smart Wireless Analysis Tool (SWAT). Based on China Unicom’s own big data and network AI platform, SWAT replaces conventional 4/5G field testing, leading to major increases in testing efficiency and dramatically reduced costs.
