The Hata Model for Suburban Areas, also known as the Okumura-Hata model for being a developed version of the Okumura Model

Okumura Model

The Okumura model for Urban Areas is a Radio propagation model that was built using the data collected in the city of Tokyo, Japan. The model is ideal for using in cities with many urban structures but not many tall blocking structures. The model served as a base for the Hata Model.Okumura model...

, is the most widely used model in radio frequency propagation for predicting the behavior of cellular transmissions in city outskirts and other rural areas. This model incorporates the graphical information from Okumura model and develops it further to better suite the need. This model also has two more varieties for transmission in Urban Areas

Hata Model predicts the total path loss

Path loss

Path loss is the reduction in power density of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system....

Microwave

Microwaves, a subset of radio waves, have wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz and 300 GHz. This broad definition includes both UHF and EHF , and various sources use different boundaries...

 or other type of cellular communications. And is a function of transmission frequency and the average path loss in urban areas.

Applicable to/under conditions

This particular version of Hata model is applicable to the transmissions just out of the cities and on rural areas where man-made structures are there but not so high and dense as in the cities. To be more precise, this model is suitable where buildings exist, but the mobile station does not have a significant variation of its height.

This model is suited for both point-to-point and broadcast

Mathematical Formulation

Hata Model for Suburban Areas is formulated as,



Where,

L_SU = Path loss in suburban areas. Unit: decibel

Decibel

The decibel is a logarithmic unit that indicates the ratio of a physical quantity relative to a specified or implied reference level. A ratio in decibels is ten times the logarithm to base 10 of the ratio of two power quantities...

f = Frequency of Transmission. Unit: megahertz (MHz).

Points to note

This model is based on Hata Model for Urban Areas and uses the median path loss from urban areas.
