Pathloss

Instructions

To understand the effect of various parameters on pathloss, please follow the following steps:


  1. Enter the Antenna gain G, Carrier frequency fc, Height of the transmitter Ht, Height of the receiver Hr.
  2. Start adjusting the position of the receiver by moving the slider.
  3. Click on register to plot the pathloss at the given distance.
  4. You can register pathloss for different distances and heights of antenna and observe the graph to understand the pathloss trends.

Instructions

To understand the effect of obstacles on the signal power, follow the following steps:


  1. Assume that the transmitter is located in the centre.
  2. Click on any location in the simulation area to generate an obstacle.
  3. Observe that the area behind the obstacle becomes reddish. This is due to the fact that the signal strength decreases.
  4. Note that blue areas indicate good signal and red once indicate bad signal.As you start placing more obstacles, it starts to become darker.
