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 30 m, and then connect to a village.

Using the Witelcom Radio Link calculator

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


 * Radio parameters
