Abstract Ini merupakan laporan akhir untuk menyiasat penghantaran 2.4GHz frekuensi diantara dua kedudukan dengan kehadiran objek dan tanpa kehadiran objek yang menghalang garis nampak. Laporan ini menyediakan ringkasan model perambatan isyarat melalui tumbuhan. Selain itu untuk mengkaji kehilangan kekuatan isyarat (tenaga atau kuasa) apabila isyarat tersebut dihantar dianatara dua kedudukan yang berbeza atau perbezaan ketumpatan tumbuhan. Hasil perbandingan antara ukuran dengan analisis matematik akan dibincangkan dalam laporan ini. Selain itu laporan ini juga turut membincangkan kemerosotan kekuatan isyarat apabila isyarat itu dihantar dalam keadaan kepadatan persekitaran berbeza dan juga parameter yang berbeza. Cabaran teras dalam projek ini ialah untuk memahami punca ralat diantara nilai pada model yang diberikan berbanding ukuran yang diambil. Kesimpulannya pelbagai cara akan digunakan menyelesaikan masalah-masalh tersebut berserta mencari kaedah lain untuk mengurangkan kehilangan dalam penghantaran isyarat seta memperbaiki dan membaikpulih prestasi. ___________________________________________________________________________________ This is the final report of the project to investigate 2.4GHZ frequency transmitted between two points with object and without obstacle (line of sight). The report provides summering previous model of signal propagation through vegetation. To study losses of signal strength (energy or power) when transmit between two points with different situation or vegetation density. Comparison result between measurement with analytical mathematical will be discuss in this paper. To discuss vegetation losses when signal traveling in different density and different parameters with the same temperature. The core of the challenge in this project to understand the cause of error between models given compare with measurement. Conclusion, solve the problems and find another method or alternative way to reduce losses at the same time improve performance
