This paper analyzed the design and development of a 16F877A microcontroller-based wireless data acquisition system. Besides, it also discussed the possibility of different existing methodologies to be linked to field data acquisition from distribution automation systems. Various existing data transmission techniques were studied, especially for wireless systems such as satellite, radio, GSM and paging. The hardware and software implementations were included. The system was used for reading, storing and analyzing data which were obtained from DAS. The wireless communications were based on the GSM network. The laboratory results were compared with the simulation results to determine final conclusion.
