The COST Hata model is a radio propagation model that extends the urban Hata model (which in turn is based on the Okumura model) to cover a more elaborated range of frequencies. It is the most often cited of the COST 231 models (EU funded research project ca. April 1986 – April 1996),〔http://www.cost.eu/domains_actions/ict/Actions/231 COST (European Cooperation in Science and Technology) website〕 also called the ''Hata Model PCS Extension''.〔 (Final report for COST Action 231, Chapter 4 ) 〕 COST (COopération européenne 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. ==Applicable to / under conditions== This model is applicable to urban areas. To further evaluate Path Loss in Suburban or Rural Quasi-open/Open Areas, this path loss has to be substituted into Urban to Rural/Urban to Suburban Conversions.
