Characterization of Outdoor to Indoor Propagation in Urban Area by Using A Combination of COST231 Walfisch-Ikegami and COST231 Multiwall Models in 1800 Mhz and 2100 Mhz

Abstract: Increasing numbers of the mobile communication users in urban city; especially indoor users cause the radio coverage prediction of outdoor to indoor becoming important. Obstacles are the main problems for outdoor to indoor propagation that weaken signal level and worsen information detection. This paper proposes a combination of COST231 Walfisch-Ikegami and COST231 Multiwall to predict the received signal. By comparing the predicted and the measured signal level in the Antara building, Medan city for both 1800… Show more

“…Based on the test results of each sensor on the prototype, data were obtained by comparing measurement results using sensors to measurement results using measuring instruments, as in Table 1. In ( 1) is used to determine the percentage of error in the reading of each sensor against the measuring instrument used [47]- [49].…”

“…Antena tersebut sederhana (low profile) dan cocok untuk komunikasi pita HF dan VHF pada sistem aeronautika. Namun, antena tersebut tidak dicetak dan tidak memiliki polarisasi vertical (vertical polarization) yang mana diperlukan untuk propagasi gelombanag radio komunikasi pada aplikasi VHF A/G (Annex 10 2001; Balanis 1997; Garg et al 2001;Pinem et al 2018Pinem et al , 2022Sihombing, Pinem, and Rezkika 2021; . Dalam Penelitian (Chang et al 2014), sebuah antena dimana frekuensinya dapat dikonfigurasi ulang untuk aplikasi radio dua arah pada pita frekuensi VHF telah dirancang.…”

“…Oleh karena itu, diperlukan sebuah model rugi-rugi lintasan untuk memprediksi rugi-rugi lintasan dari luar ke dalam gedung. Sehingga, model tersebut dapat digunakan sebagai referensi untuk meningkatkan kinerja antena pemancar yang ditempatkan di luar gedung untuk mendukung komunikasi nirkabel di dalam gedung [1], [2].…”
