Hi mates,
Sorry to disturb you, My name is Joush Cadwell, I’m the beginner in RF planning and Optimiztion
When using Atoll and others planning tool, I have a question about defining GSM propagation model, hope your help in this
As you know, in theory, we can define loss through some models such as Hata, Cost-Hata…In this case, we using k factors to define it, and each terrain ( such as Dense urban, urban, suburban, rural, highway…) will have different k factors ( as attached file)
But, in another voice, we can define loss by clutter, such as loss of sea, island water, forest, urban, villages, airport, industrial zone, building…And all of them have the same k factors ( as attached file)
So, pls give me your advice in this. What’s the right way to define propagation model? And the exact number of loss or k factors we should use to put in planning tool ?
My band is 1800 MHz
Hope to get your support. Wish health and success for you
