ABSTRAKSI: Enhanced Data rates for GSM Evolution (EDGE) merupakan salah satu standar untuk komunikasi data wireless yang diimplementasikan pada jaringan selular GSM dan merupakan tahapan lanjutan dalam evolusi menuju mobile multimedia communication. EDGE merupakan evolusi terakhir teknologi sistem seluler GSM menuju UMTS/UTRAN (UMTS Terestrial Radio Access Network) dengan kecepatan paket data 473,6 kbps.
Tugas akhir ini akan menghadirkan analisa performansi kanal sharing untuk mendukung transmisi suara dan data secara circuit switched dan packet switched dalam jaringan GSM/EDGE. Penelitian akan dilakukan pada tiga jenis kanal sharing pada arah uplink dan downlink : Partial Sharing Schemes, Complete Partitioning serta Complete Sharing Schemes.
Perbandingan kanal sharing menunjukkan perbedaan performansi jaringan yang dilihat dari delay paket rata – rata, probabilitas blocking paket dan suara, serta pengaruh voice call load pada jaringan. Hasil penelitian memberikan rekomendasi batas maximum offered traffic yang bisa dilayani 1,2673 Erlang untuk jaringan dengan N = 8 dan beban suara 80%. Namun dengan nilai probabilitas blocking suara yang besar, perlu dilakukan penyesuaian dengan potensi trafik dan performansi optimum per kanal.
Kata Kunci : ABSTRACT: Enhanced Data rates For GSM Evolution ( EDGE) is one of standards for wireless data communication which is implemented to GSM cellular network and as further step in the evolution to mobile multimedia communication. EDGE is the last evolution of the GSM cellular system technology to UMTS/UTRAN ( UMTS Terrestrial Radio Access Network) with the rate of data packet 473,6 kbps.
This final assignment will present an analytical model to compare the performance of channel sharing in supporting voice and data transmition by circuit switched and packet switched in GSM/EDGE network. Assignment will research three kinds of channel sharing on uplink and downlink direction, they are : Partial Sharing Schemes, Complete Partitioning serta Complete Sharing Schemes.
The comparison of channel Sharing shows the differences network performance which is looked from the average packet delay, blocking probability of packet data and voice, and also the effect of voice call load in the network.
The result of research gives recommendation of offered traffic maximum that can be served 1,2673 Erlang for network with total channel (N) = 8 and the voice call load 80%. But, because of voice blocking probability is high in the network, an adjustment upon traffic potential and optimum performance per channel is recommended.
