Many websites, books, blogs, manuals can be found about the theory of RAN (Radio Access Network) or RF Optimization and as important as the theory may be, practice always has a different perspective. This blog presents practical cases, call scenarios, handover issues, soft and hard parameter settings, resolution of user blocking, improvement of TCH availability, antenna electrical mechanical tilt and elevation azimuth angle recommendations, reduction of call drop rate (CDR/DCR), increasing TCH utlization, cell and TRX level optimization, cell frequency planning, MAIO configuration, neighbor audit, layer 2 and layer 3 messages analysis, TEMS and drive testing tutorials and documents, pre and post processing of log files and many more that would provide a comprehensive guide to a telecom engineer working in a multi-vendor telecom operator of 2G, 2.5G, 3G, 4G/LTE network would experience in his daily professional life.
