Type Approval Work at BGAN RAN equipment. I have made test work on L-band (950 - 2150 MHz) equipment for use in Inmarsat I6 system. I have set up test equipment for making measurement on L-band converter board. Measurement data are used for report writing for Inmarsat. Besides I have experience with using Rohde & Schwarz RF test equipment and Microwave Office for RF simulation. Type Approval Work at BGAN RAN equipment.
