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.phpFurther 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:
- identify potential fibre termination points (in which villages in the surrounding to I find fibre?)
Step 3:
- use the tool for finding the line of sight communications, or minimum relay posts
Example:
- link from Mto wa Mbu to Selela
- Radio parameters
