Explain the significance of Walfisch and Bertoni Model.
Answers
Hiiiii mate here your answer ✔️ ✔️ ____________________________ Walfisch –Bertoni model, called also as diffracting screens model [1], is a semi -deterministic model valid for situations uniform building heights and spacing. The model approach the buildings as absorbing diffracting edges and finds the field strength at low grazing angles at what field is settled to a value. Further simplification is made by assuming an elevated fixed antenna achieved by using the local plane wave approximation to calculate the influence of buildings on field strength on the spherical wave radiation by elevated antenna. (1) The model firstly finds the amplitude Q(a) of the field at roof tops due to a plane wave of unit amplitude incident at the glancing angle a on a number of buildings. It is found that for large number of buildings, Q(a) settles to a constant value. Then, this value is multiplied by following factor (1) to find the field amplitude at the mobile. _____________________________ ❤️⭐I hope you mark as brainlist answer⭐❤️✨✨✨
