Radio Network Optimization (RNO) technicians in South Africa play a
crucial role in ensuring that mobile networks (2G, 3G, 4G/LTE, and 5G) meet
performance, capacity, and quality standards. Working on projects for major
operators (e.g., MTN, Vodacom, Cell C, Telkom) and vendors (Huawei, Ericsson,
Nokia), these professionals analyse network data to optimize coverage and user
experience, often working with Drive Test data and Network Management Systems
(NMS).
