Abstract

The objective of this project is to design, test, install, and finally transfer over a wireless communication system to the Smallholders Foundation, a non-government organization (NGO) with the goal of boosting small-scale agricultural production, self-sustaining growth, and employment in rural areas of Nigeria. This system will have the capability to have more than 4 simultaneous voice channels, use off-the-shelf hardware and software components, and create a private branch exchange (PBX) with the use of the open source Asterisk software (at customer request, an asterisk for windows OS was used). Note that we will configure and install 4 Wi-Fi handsets in order to extend the reach of communications into rural communities in the Imo State in Nigeria. This joint effort between The Smallholders Foundation and The University of Colorado additionally wishes that this system, the process, and plans be well documented to permit the duplication of the same system in other developing communities throughout the world.

The project initiative was developed based on past experiences with interactive radio systems in rural developing communities in Africa. The system developed by this project will permits farmers in rural communities to communicate with the radio station through a soft PBX setup by using Wi-Fi phones, Voice Over IP (VOIP) protocol, and the Asterisk server. This operates much in the same way as an existing data wireless system (a.k.a. a Wi-Fi network), except that the access point for all users is installed on and broadcast from the local radio station.

The System components will use IEEE 802.11a/g and Session Initiation Protocol (SIP) compatible materials. The system will be designed to meet all applicable local codes, standards, regulations and permitting requirements in Nigeria. The Smallholders Foundation will provide a reliable source of electricity to power the system. Training and maintenance plans will be developed for the end-users and the server operator to ensure the safe operation of the new system.
