Sample Projects

Some of the projects that were dear to me

Extending Internet to new life camp houses

Adding Internet coverage to one side of Baissour

School Management System

Connecting Jungle site with Head Office

Extending Internet to new life camp houses

Location: Life camp, Port Harcourt, Nigeria.
Situation: Additional staff necessitated the addition of two new houses, but unfortunately far from the existing group of company houses. New staff were not getting the company provided Internet connection in their houses.

Solution: Installation of 5 GHz Ubiquity devices to extend our Internet line to the other side of the life camp, then properly wiring it to routers inside their houses.

Adding Internet coverage to one side of Baissour

Location: Northern side of Baissour mountain.
Situation: Due to the mountainous terrain of the town of Baissour, and lack of infrastructure from the government, one side of the mountain was not receiving coverage, as local ISPs decided to cover the more populous side only.

Solution: 5 GHz radios were installed in key locations of the town to receive Internet from the town of Keyfoun on the facing mountain. New customers registering for the service were then equipped with 2.4 GHz stations if near the main radios, and 5 GHz stations if far, connected to proper routers inside their houses.
Monitoring for malicious radio interference was a daily job in a hostile environment of competing ISPs, and prevention methods were always available.

School Management System

A school management system, based on C++/Qt, with a server/client architecture.
The system is capable of storing and calculating student grades, grade charts, timesheets.
It can generate timetables based on teacher availability and class requirements.
Simple to use program, highly efficient, modern, and very customizable.

Connecting Jungle site with Head Office

Location: Machinery yard, Ukana jungles, Akwa Ibom, Nigeria. 3 buildings, only one with an internal network.
Situation: Communication isolation except for mobile phone networks. Local server with a custom software solution, MySQL based, and several workstations for data entry.

Solution: The yard received a complete network overhaul, and a wireless stations to connect the 3 buildings. workstations were installed in the other buildings to improve data entry speed at their respective locations. Created a solution to merge yard data with the head office server, and keeping both sites synchronized. Satellite Internet was installed, and properly secured over the new network, for the synchronization process, and limited to personnel with emailing needs. Few months later, a proper procedure for giving access to new personnel and devices was established and the yard manager received a detailed training course on how to use it, and to better understand the costs incurred on the company from improper usage of satellite Internet.
