Universitas Islam Negeri Sunan Gunung Djati Bandung merupakan salah satu instansi pendidikan yang memanfaatkan wireless LAN sebagai media pembelajaran dan informasi, namun banyaknya penggunaan frekuensi dan channel pada wireless LAN dapat menyebabkan overlap hingga terjadi interferensi sinyal. Agar mendapatkan coverage jaringan yang baik pada perangkat outdoor wireless LAN, diperlukan suatu perencanaan dalam penempatan posisi antena dan perhitungan Link Budget yang terdiri dari free space loss, effective isotropically radiated power, received signal level dan system operating margin. Selain itu perhitungan dilakukan secara simulasi dengan menggunakan software Radio Mobile untuk melihat hasil coverage area secara visual. Pengukuran jaringan yang dilakukan terdiri dari 1 antena Server dan 3 access point yang ditempatkan pada posisi yang telah ditentukan berdasarkan kondisi eksisting. Hasil rancangan jaringan yang dianalisis menggunakan perhitungan Link Budget secara teori maupun simulasi  dengan nilai parameter System Operating Margin (SOM) terbesar pada server sebesar 47,26 dB, sedangkan pada access point#1 46,26 dB, access point#2 45,76 dB dan access point#3 39,5 dB dimana telah memenuhi batas perancangan sinyal yang baik.

Calculation Results

The main changes in the telecommunication during these present days come mainly from wired technology to wireless technology. The Wireless LAN (WLAN) configuration consists of an access point, connected to users using air medium. The postgraduate building of Universitas Udayana has been equipped with a wireless network, supporting the study activities within the building. This research explains regarding the signal level quality and the Quality of Service (QoS) by analyzing the Wi-Fi coverage. The measurements were divided into two models, with and without barriers. The highest result comes to -42 dBm, conversely, the lowest is -82 dBm. Thus, the results show that the throughput value is 3.97 Mbps. Within the maximum bandwidth of 10 Mbps, the average packet-loss is not more than 3%. The delay measurement provides a result of not more than 100 ms, and the jitter obtained is 0.04. According to the digital floor plan, the calculation results of the coverage area match the signal level measurement.

Salah satu perubahan yang sangat pesat di dalam jaringan komputer adalah penggunaan wireless LAN (WLAN) untuk mengakses jaringan baik lokal maupun internet. Salah satu cara penambahan Access Point (AP) yang tidak mengubah konfigurasi software yang telah di gunakan yaitu menggunakan jaringan Wireless Distribution System Mesh (WDS). Penggunaan WDS mesh di Universitas Muhammmadiyah Jember memungkinkan konfigurasi wireless yang sedikit berbeda agar dapat mengurangi terputusnya koneksi pada pengguna karena jangkauan area jaringan wireless. Salah satu langkah adalah dengan menggunakan beberapa perangkat Acesss Point menjadi satu kesatuan untuk menangani kasus terputusnya koneksi dengan memanfaatkan service jaringan yaitu WDS Mesh. Wireless Distribution System atau (WDS) Mesh mampu meng- coverage area wifi di Universitas Muhammadiyah Jember dan hasil ujicoba serta analisa device client terhadap AP yang sudah di WDS Mesh dengan parameter Signal Strength, CCQ, Signal to Noise, Throughput adalah Excellent (Bagus)

The problem that often occurs in malls or supermarkets is the use of EDC as a non-cash payment tool for alternative customers. However, the use of EDC machines sometimes experiences problems, namely when customers enter data so that transactions take longer, so this study aims to analyze the optimization of EDC placement in shopping center buildings. This research method is to measure the parameters, namely the RSCP and the closest antenna coverage from the EDC. In this study, three samples were taken, namely Cassa 1, 2 and 3 at Matahari Department Store Malang Town Square. The results of this study were obtained that the Drive Test in the Matahari room showed that Cassa-1, Cassa-2 and Cassa-3 received RSCP with green color which means good. Two of the three tools, namely Drive Test and Mobile can display RSCP with a value that is not too much difference. Especially for EDC is only able to visually display the RSCP and the results of previous calculations, the value of ten antennas which is in the Matahari room has a coverage area below 10 m. And the UG-12 antenna, which is the closest antenna to Cassa-3,  that is outside the antenna coverage, while the UG-08 antenna can still reach the Cassa-3 area. This shows that the placement of EDC has met the requirements to get adequate signal quality and the position of the Cassa table can be moved according to the antenna coverage calculation on the Link budget and Path Loss calculations
