This paper presents an initial result of research from rain rate measurements in mataram lombok indonesia. rain rate is intruder for channel communication espesially in local multipoint distribution service transmission at 30 GHz. channel charactization in order to understand and mitigate the problem. parameter statistic of rain rate to proceces predication used design and evaluation LDMS system. data rain rate from urban mensurement made channel noise used union to generate signal rain rate. mean and variance for the check normal data used large-scale fading. large-scale fading is lognormal distribute. noise in channel from rain rate made classification in colour noise.
