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

Analisis perhitungan dan pengukuran untuk membandingkan Model Okumura-Hatta, Cost231-Hatta dan Walfisch Ikegami sebagai formula link budget pada lintas komunikasi down link base station, perhitungan menggunakan data dari salah satu operator di Indonesia wilayah Malang. Hasil penelitian dapat digunakan sebagai suatu masukan atau rekomendasi bagi operator seluler/vendor sebagai bahan pertimbangan bagi operator menggunakan formula link budget untuk memprediksi rugi-rugi propagasi yang tepat dengan teknologi yang digunakan dan disesuaikan dengan morfologi. Parameter yang dianalisis adalah radius sel sebagai jarak maksimal yang dapat dijangkau oleh base station. Perbandingan nilai radius sel hasil perhitungan dan pengukuran dianalisis untuk mengetahui hasil yang mendekati dengan nilai yang sebenarnya. Perhitungan link budget coverage area menggunakan 3 model, yaitul Okumura-Hatta untuk menghitung coverage area sistem GSM, Cost-231 Hatta untuk sistem DCS, dan Walfisch Ikegami untuk sistem UMTS 2100. Pengukuran menggunakan drive test untuk mengukur level daya sinyal yang dipancarkan oleh base station. Hasil drive test diperoleh nilai radius sel terjauh adalah 980 m dan nilai level daya sebesar -91 dBm, sedangkan hasil perhitungan nilai radius sel nilai yang mendekati dengan nilai pengukuran adalah model Walfisch Ikegami nilai radius sel sebesar 1,06 km dan 1,05 km dan nilai level daya sebesar - 90 dBm.

In WCDMA system, signal service coverage determines quality service of telecommunication network . To give maximum network service at Jl. Tengah I Kerobokan area, thus requiring the study of the arrangement of the cell coverage on BTS Protpeliatan Sector ? and BTS AnyarKaja Sektor ?. The method used is calculation the distance of base station with proper propagation model which suits the condition of both base stations, also antenna azimuth and tilting were given, and simuation using Atoll software to see the predicted coverage area of BTS. As the result, suitable propagation for BTS Protpeliatan Sector ? is Okumurra Hatta model and BTS AnyarKaja Sektor ? is Cost 231 Hatta model, maximum coverage signal service of BTS Protpeliatan Sector ? is 1,17 km and for BTS AnyarKaja Sektor ? is 1,11 km. Requirement of antenna tilt change from 0º to 0,95º for BTS Protpeliatan Sektor ? and for pada BTS AnyarKaja Sektor ?, antenna tilt change from 0º to 1º and change of 30º antenna sector direction from 180º to 210º. From simulation using Atoll software with above parameters, acknowledge that area of Jl. Tengah I Kerobokan already get maximum service with received signal level pass the KPI (Key Performance Indicator) standard.  Dalam sistem WCDMA, cakupan layanan sinyal merupakan penentu kualitas layanan jaringan telekomunikasi. Untuk memberikan layanan jaringan yang  maksimal di area Jl. Tengah I Kerobokan maka dilakukan analisis penataan cakupan layanan sel pada BTS Protpeliatan Sektor ? dan BTS AnyarKaja Sektor ?. Metode yang digunakan yaitu perhitungan jarak cakupan BTS dengan model propagasi yang paling sesuai dengan kondisi kedua BTS, penentuan arah azimuth dan tilting antena, serta simulasi menggunakan Atoll untuk melihat prediksi cakupan layanan BTS. Didapatkan bahwa model propagasi yang sesuai dengan BTS Protpeliatan Sektor ? adalah  model Okumurra Hatta dan BTS AnyarKaja Sektor ? adalah model Cost 231 Hatta, jarak cakupan layanan maksimum BTS Protpeliatan Sektor ? adalah sejauh 1,17 km dan pada BTS AnyarKaja Sektor ? sejauh 1, 11 km. Diperlukan perubahan tilt antena dari 0º menjadi 0,95º  pada BTS Protpeliatan Sektor ? dan perubahan sudut tilt dari 0º menjadi 1º serta perubahan arah sekorisasi antena sebesar 30º dari 180º menjadi 210 º pada BTS AnyarKaja Sektor ?. Dari hasil simulasi yang dilakukan menggunakan software Atoll dengan parameter tersebut, diketahui bahwa area Jl.

Coverage is needed to determine the amount of signal coverage that can be reached by the antenna at the base station. Therefore, in order to know the coverage area of ??a base station, a link budget coverage area application is needed. The purpose of making a link budget coverage area calculation application system at a base station is to assist in calculating the link budget to determine the coverage area of ??a base station and is also used as a learning module for mobile communication systems at State Polytechnic of Malang. The method of determining the coverage area is done in 2 ways, namely the calculation using the application and the drive test. The method of calculating the link budget coverage area used is 3 models, the Okumura-Hatta model is used to calculate the GSM system coverage area, the Cost-231 Hatta model for the DCS system, and the Walfisch Ikegami model for the UMTS 2100 system. measurement of the signal level around the base station area. The comparison of the coverage area between the measurement and calculation results is almost close to the difference in coverage of less than 100 m. Wherefrom the results of the drive test, the farthest range is 980 m with a signal level value of -91 dBm. Meanwhile, from the calculation side, the results obtained coverage of 1.06 km and 1.05 km with a signal level of -90 dBm

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.
