Abstract

Semakin berkembangnya teknologi menuntut ketersediaan komunikasi radio seluler yang dapat menunjang berbagai macam kegiatan. Utamanya di daerah metropolitan dimana mobilitas pelanggan semakin tinggi. Namun demikian gedung-gedung yang menjulang tinggi seringkali membuat cakupan base station berkurang akibat rugi-rugi lintasan propagasi. Hal ini dapat mengganggu terjalinnya komunikasi seluler. Pada sistem radio seluler TDMA untuk dapat meningkatkan cakupan base station digunakan peer-to-peer relaying. Dengan memperhitungkan pathloss, lognormal shadowing dan Rayleigh fading baik dengan menggunakan power kontrol maupun tanpa power kontrol didapatkan hasil bahwa relay dapat meningkatkan cakupan base station. Sehingga base station dapat melayani pelanggan dengan baik. Namun demikian hasil ini tidak berlaku bagi radius sel 0,5 Km dan 2 Km. Pada kondisi yang diasumsikan dalam penelitian ini (frekuensi 2 GHz dan daya 1 Watt) peer-to-peer relaying memberikan hasil yang maksimal jika diterapkan pada radius sel 1 Km. Yaitu dapat meningkatkan cakupan sebesar 50%.

Developing technology demands the availability of selular radio communication to enhance various activity, especially on metropolitan area in which customer mobility is increasing. How ever, high buildings often reduacing the coverage of base station due to path loss propagation. This, leads to the disturbanses the selular communication. On the TDMA selular radio system, peer-to-peer relaying is employed to improve the coverage of base station. By calculating path loss, lognormal shadowing and Rayleigh fading either with power control or without power control, it was indicated that relaying improved the coverage of base station, as the result the base station surve well. How ever the result was not effective on the sel with radius 0,5 Km and 2 Km. On the assume condition (frequency 2 GHz and power 1 Watt) peer-to-peer relaying gives maximum result if it was applied on the sel with radius 1 Km. That is improve the coverage 50%.
