Comparison of Okumura, Hata and COST-231 Models on the Basis of Path Loss and Signal Strength

Abstract: Radio propagation is essential for emerging technologies with appropriate design, deployment and management strategies for any wireless network. It is heavily site specific and can vary significantly depending on terrain, frequency of operation, velocity of mobile terminal, interface sources and other dynamic factor. Accurate characterization of radio channel through key parameters and a mathematical model is important for predicting signal coverage, achievable data rates, BER and Antenna gain.Large scale path… Show more

“…However, the signal coverage area can be increased with a suitable power amplifier. Specifically, based on the COST 231 radio propagation model [48], we calculated that by mounting a USRP at a height of 10m (e.g., on a street lamp) and amplifying the power by 10 dB, it is possible to deny LTE and non-LTE services for every subscriber in a cell. For a reference, OpenBTS projects [49], [50] use USRPs to provide GSM coverage in rural areas with >2 km coverage with an external power amplifier and antenna.…”

“…Model ini telah divalidasi secara luas untuk jaringan mobile. Selain itu sebagian besar model tersebut didasarkan pada interpretasi sistematis terhadap data pengukuran yang diperoleh di area layanan tertentu [3]. Oleh karena itu pada penelitian ini mengambil perbandingan dari dua kategori pemodelan yaitu dari kategori empiris adalan model pathloss COST-231 Hata sedangkan dari kategori deterministik adalah model pathloss Walfisch Ikegami.…”

“…Menghitung sensitifitas penerima (sensitivity receiver) Sensitifitas penerima (Pmin), seperti ditunjukkan pada formula (1), adalah daya minimum yang diterima dimana persyaratan throughput masih terpenuhi (Abdulkafi et al, 2012) atau rata-rata kuat sinyal minimum yang ditangkap antena dengan SINR yang cukup untuk skema modulasi yang digunakan untuk memenuhi persyaratan throughput minimum sebesar 95% dari nilai throughput maksimum yang mungkin (Belhouchet & Ebdelli, 2010 Dengan mengasumsikan model propagasi tertentu maka akan diperoleh radius cakupan dari sebuah BS berdasarkan rugi-rugi lintasan maksimum yang diperoleh dari perhitungan sebelumnya. Model propagasi dapat diklasifikasikan menjadi model empiris dan model deterministik (Singh, 2012 …”

“…Dari maksimum path loss yang diperoleh, selanjutnya dapat dicari jarak terjauh pemancar ke penerima dengan menggunakan model propagasi Okumura-Hatta. Model propagasi Okumura-Hatta dapat digunakan pada frekuensi pembawa hingga 1500 MHz (Singh, 2012). Asumsi ketinggian antenna yang digunakan yaitu 30 m untuk antena pemancar dan 1.5 m untuk antena penerima (ECC, 2013).…”
