Throughout the world, there are many developing countries that do not have the luxury of possessing telecommunication stations for cell phone use.

GE Corporation assigned engineering students to solve this problem for these communities and nations, by creating a No Grid Telecom Base Station

Team Five created a station that uses sustainable energy sources and optimizes green power for infrastructures without connections AC utility grid.

Introduction

Power Telecom station with sustainable energy. Solar Power Create constant 1.2-kW load, with additional load

created to power the hut equipment Integrate suitable “Hybrid” application to obtain

minimum operating costs

Mission Statement

707,400 people 295 sq. kilometers Economy

Mombasa, Kenya

In Mombasa, Kenya, there is already a large amount of cellular towers.

In this region, the GE Telecom Station will compete with local cellular companies, but will offer a station that runs off sustainable energy instead of utility grid power.

This cost efficient system will be able to use green technology to lower the maintenance cost of the station, making the cellular market more competitive.
