Data Communication Design and Implementation for Marine Radio Using UHF Spectrum

摘要

Affordable communication radios for fishermen do not usually have data communication feature which is able to send important informations in text format with the updated coordinate locations. The lack of standard radio for fishermen communication could cause a big risk for fishermen's safety. In this paper, data communication system using UHF spectrum for marine radio was designed and implemented. The system design was done by utilizing a micro controller with its supporting modules. The implemented data communication system could work on 300-400 MHz frequency with its bit rate 32,59 byte/s and 30 meters for communication range. The sent information in this data communication consisted of a message format with coordinate location and ship identity code inside of it.
