Radio connectivity to villages

This pages lists information for connectivity to the National ICT Broadband Backbone Network of Tanzania. More info at http://www.nictbb.co.tz/map.php

Further links to the Rural Telecommunication Project of the government is available from the information page of the Universal Communications Service Access Fund (UCSAF) at http://www.ucsaf.go.tz, with the latest report (August 2016) available from http://www.ucsaf.go.tz/files/publications/attachments/9fc769060924bccfaa274df1ab782ea2.pdf

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
