(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 231 models (EU funded research project ca. April 1986 – April 1996), also called the ''Hata Model PCS Extension''. This model is the combination of empirical and deterministic models for estimating path loss in an urban area over frequency range of 800 MHz to 2000 MHz.Final report for COST Action 231, Chapter 4
COST In Production (economics), production, research, retail, and accounting, a cost is the value of money that has been used up to produce something or deliver a service, and hence is not available for use anymore. In business, the cost may be one o ...
(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 based on experimental measurements in multiple cities across Europe.


Applicable to / under conditions

This model is applicable to macro cells in urban areas. To further evaluate Path Loss in suburban or rural (quasi-)open areas, this path loss has to be substituted into ''Urban to Rural'' / ''Urban to Suburban'' Conversions. (Ray GAO, 09 Sep 2007)


Coverage

*Frequency: 1500–2000 MHz *
Mobile station A mobile station (MS) comprises all user equipment and software needed for communication with a mobile network. The term refers to the global system connected to the mobile network, i.e. a mobile phone or mobile computer connected using a mobile ...
antenna height: 1–10 m *
Base station Base station (or base radio station) is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a " land station in the land mobile service." The term is used in the context of mobile telephony, wireless c ...
antenna height: 30–200 m *Link distance: 1–20 km


Mathematical formulation

The COST Hata model is formulated as, L_b = 46.3 + 33.9 \log_ \frac\text - 13.82 \log_ \frac\text - a(h_R, f) + \left( 44.9 - 6.55 \log_ \frac\text \right) \log_ \frac\text + C_m where,


Limitations

This model requires that the base station antenna is higher than all adjacent rooftops.
