Calculation of radio propagation

There are several tools available to calculate the distance from a given "point of presence (POP)" (star in the map) to a village. You just select a town, and assume a mast height of 6 m, and then connect to a village.

The following tools are suggested

Example of Selela

Step 1: Find the GPS coordinates of the Village

  • -3.204469,35.943328 (for Selela)

Step 2:

  • who are the operators in the region
  • which neighbour villages are connected

Step 3:

  • identify potential fibre termination points (in which villages in the surrounding to I find fibre?)
  • alternatively, identify the towers of the mobile operators in the neighbour villages

Step 4:

  • use the tool for finding the line of sight communications, or minimum relay posts

Example:

  • link from Mto wa Mbu to Selela
