Abstract

Jaringan komputer didesain berdasarkan fungsi yang disesuaikan dengan desain bangunan yang harus dianalisis untuk mempertimbangkan intensitas penggunaan dan pemeliharaannya. Studi kasus kali ini berada pada Gedung Universitas di Bandung yang menggunakan kombinasi fiber optic dan jaringan nirkabel menggunakan frekuensi 2,4GHz & 5GHz. Kondisi existing diuji dalam tahapan survei lapangan dan ditemukan beberapa permasalahan yaitu tingginya interferensi frekuensi sinyal nirkabel, penggunaan channel band tidak terkonfigurasi dengan baik yang menyebabkan terganggunya koneksi ketika berada pada dua area akses poin terdekatnya, serta terdapat blank spot membuat perangkat pengguna tidak dapat terkoneksi. Optimasi jaringan nirkabel perlu dilakukan untuk menyelesaikan masalah yang ditemukan. Metode yang digunakan untuk proses optimasi jaringan adalah Network Development Life Cycle (NDLC) yang terdiri dari tahap Analisis, Desain dan Simulation Prototyping, serta pengukuran menggunakan parameter Quality of Service (QoS). Hasil pengujian menunjukkan tingginya interference area karena konfigurasi pada akses poin dapat menggunakan channel band yang sama, serta akses poin yang bertipe wall-mount namun digunakan pada plafon sehingga bisa menginterferensi jaringan atas maupun bawahnya. Pengujian QoS dilakukan sesuai standar TIPHON yaitu parameter throughput>1kbps, packet loss <3%, dan delay<150ms. Rekomendasi untuk mengoptimasi jaringan adalah dengan mengubah penggunaan channel band dengan format channel 1-6-11 bagi ruangan yang berdekatan agar meminimalisir interferensi antar channel band yang sama. Dan juga dilakukan simulasi perubahan perangkat bertipe ceiling-mount sesungguhnya, menunjukkan interference yang menurun baik ke lantai atas maupun bawahnya.

Abstract

Computer network designed according to its functions and building design which must be analyzed toconsider usage intensity and maintenance. This paper’s study case is in one of the buildings in University atBandung which uses fiber optic and wireless network for both 2,4GHz and 5GHz frequencies. Existingconditions were tested in site surveys which are high frequency interference of wireless signals,misconfigured channel bands caused frequent disconnections close to two different access points, and thereare blank spots causing user’s devices cannot properly connect to network. Wireless network optimizationneeds to be done to solve its problems. Method used is the Network Development Life Cycle (NDLC) whichconsists of Analysis, Design, and Simulation Prototyping phases, and performance measurements usingQuality of Service (QoS) parameters. Site survey results showed many high interference areas caused bychannel misconfiguration in each access point that the same channel can be used for adjacent access points,misplacing wall-mounted access points on ceiling which can interfering both upper floor and lower floornetworks. QoS performance measurements to match TIPHON Standardization for throughput is higher than1kbps, packet loss lower than 3%, and delay lower than 150ms. Recommendation for optimizing network isproperly configuring channel band using non-overlapping channel configuration (1-6-11) for all adjacentaccess points, and there is simulation for replacing wall-mounted access points that placed on the ceiling toa ceiling-mounted type access point. It showed a decreasing interference in the entire network, whether itson the same floor or between upper and lower floor.
