Jul 01,  · COST Hata Model Extends the validity region of Okumura-Hata Model to - MHz range which encompass the MHz frequency which is used for 2G and 3G cellular systems. COST Hata Model defined by: C is 0 in small and medium-sized cities “Urban Areas”, and Suburban Areas. C is 3 in Metropolitan Areas. COST 1. Description. The COST model [] is a semi-empirical path loss model, resulting from the combination of Walfisch-Bertoni [3] and Ikegami [4] models. It is recommended for macro-cells in urban and suburban scenarios, showing very good results for path loss calculations for base station antennas located above the average roof height. Cost Hata Model First generation GSM systems operate at MHz band. As the demand on the service increased, allocation of new channels to the service has been provided by assigning MHz band to the system. Hence, first system can use Hata Model for prediction since Hata Model covers frequency range of to MHz.

COST 1. Description. The COST model [] is a semi-empirical path loss model, resulting from the combination of Walfisch-Bertoni [3] and Ikegami [4] models. It is recommended for macro-cells in urban and suburban scenarios, showing very good results for path loss calculations for base station antennas located above the average roof height. Okumura Hata Model formula | COST extension of Hata Model. This page describes Okumura Hata Model basics, Hata model formula and COST extension of Okumura Hata Model. The hata model is empirical formulation of graphical path loss (PL) data. It is valid in the range from MHz to MHz. It is provided by Okumura and hence the name. simulations, the adjusted COST Hata model gave better predictions with minimum MSE and SD that are within the acceptable values. The adjusted COST Hata can accurately be used for predicting the radio characteristic of Rivers State. Keywords: Path loss prediction, cellular transmission, COST Hata model, Mean Square Error, Standard. The COST Hata model is a radio propagation model (i.e. path loss) that extends the urban Hata model (which in turn is based on the Okumura model) to cover a more elaborated range of frequencies (up to 2 GHz).It is the most often cited of the COST models (EU funded research project ca. April – April ), also called the Hata Model PCS Extension. Cost Hata Model First generation GSM systems operate at MHz band. As the demand on the service increased, allocation of new channels to the service has been provided by assigning MHz band to the system. Hence, first system can use Hata Model for prediction since Hata Model covers frequency range of to MHz. These include Hata model, Okumura model, COST Hata model. On the other hand, deterministic models are very accurate. Some of the examples include Ray Tracing and Ikegami model. As mentioned earlier, semi-empirical models are based on both empirical data and deterministic aspects. Cost Walfisch-Ikegami model is. Path Loss Calculator Hata Model, COST Model and SUI Model. All these models have certain limitations such as the frequency of operation over which these models are applicable, distance Subcategory: Science Software. Since some of the working frequencies of the LTE networks are GHz and GHz have exceeded the band range of the standard Cost Hata model, that is, MHz to MHz. Therefore, in the actual LTE system design, the standard CostHata model must be corrected based on the CW test result. Jul 01,  · COST Hata Model Extends the validity region of Okumura-Hata Model to - MHz range which encompass the MHz frequency which is used for 2G and 3G cellular systems. COST Hata Model defined by: C is 0 in small and medium-sized cities “Urban Areas”, and Suburban Areas. C is 3 in Metropolitan Areas. This Okumura-Hata model, valid from MHz to GHz, was later extended to PCS frequencies, GHz to 2 GHz, by the COST project (, ch. 4), and is referred to as the COST Hata model; it is still widely used by cellular operators. The model provides good path loss estimates for large urban cells (1 to 20 km), and a wide range of.Hata's model has been derived from curves plotted by Okumura. The model 10 meters. Cost - Hata extends Hata's model to 2 GHz. Path Loss Calculator. The COST model [] is a semi-empirical path loss model, resulting from the Compared to previous models such as Okumura-Hata, the calculation. Based on the Okumura-Hata method, the model makes a correction for COST Deterministic calculation method valid in the frequency range from The COST Hata model is a radio propagation model (i.e. path loss) that extends the urban Hata It is the most often cited of the COST models (EU funded research project ca.
