The COST Hata model is a
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 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 antenna height: 1–10 m
- Base station antenna height: 30–200 m
- Link distance: 1–20 km
Mathematical formulation
The COST Hata model is formulated as,
where,
Median path loss. Unit: decibel (dB) | |
Frequency of Transmission. Unit: megahertz (MHz)
| |
Base station antenna effective height. Unit: meter (m) | |
Link distance. Unit: Kilometer (km) | |
Mobile station antenna effective height. Unit: meter (m) | |
Hata model for urban areas .
For suburban or rural environments this factor is defined as,
and, for urban environments (i.e. large cities) as,
| |
Constant offset. Unit: decibel (dB). Defined as,
|
Limitations
This model requires that the base station antenna is higher than all adjacent rooftops.
