Exercise 1
- Function (frequency , distance)
- Pathloss equation - f(distance, wavelength)
- Wavelength - f(frequency, speed of radio wave)
- Main Program
- Define frequencies, distances, initialise pathloss matrix
- For each frequency -> calculate pathloss
- Plot the results

3. Exercise 2
 Function (Ptx, Prx, Frequency)
– Initialise distance
– Calculate the desired path loss using the simplified link budget
– While loop
 Calculate pathloss using the function from Exercise 1
 Analyze value depending off desired pathloss

Desired
pathloss

4. Exercise 3
 Function (d, ht,hr,terrain,frequency)
– For each terrain type define a,b,c parameters
– You need: ∆PLf, ∆PLht, , d0, d0’,ɤ λ, A
– Calculate the pathloss
 Main Program
– Define frequency, height of tranismitter
and receiver, terrain type, distance, matrix
– For the whole distance calculate
pathloss
– Plot the pathloss vs. distance.
