Detailed Description

The COST-Hata-Model is the most often cited of the COST 231 models.

Also called the Hata Model PCS Extension, it is a radio propagation model that extends the Hata Model (which in turn is based on the Okumura Model) to cover a more elaborated range of frequencies. COST (COperation europ�enne dans le domaine de la recherche Scientifique et Technique) is a European Union Forum for cooperative scientific research which has developed this model accordingly to various experiments and researches. This model is applicable to urban areas. To further evaluate Path Loss in Suburban or Rural Quasi-open/Open Areas. Frequency: 1500 MHz to 2000 MHz Mobile Station Antenna Height: 1 up to 10m Base station Antenna Height: 30m to 200m Link Distance:up to 20 km
