The object of this project is to design a telecom cell phone base station system in a developing region that uses an alternative

energy source to run the base station Needs

◦ Reliable and sustainable energy source◦ Diesel generator◦ Sodium metal halide battery◦ Area with no or unreliable energy grid◦ Able to be implemented with minimal resources and reusable across developing

nations Requirements

◦ Country in a no grid application◦ Constant 1.2 kW work load◦ BTS DC equipment at -48 VDC◦ Diesel driven DC generator set◦ Alternative energy source◦ Sodium metal halide battery◦ Appropriate hut equipment

Selecting a Country to Implement Telecom Base Station (cont.)

Weighted Selection Matrix for Choosing a Country for Telecom Base StationRankings based on a value from 1 to 5 with 5 being the highest and are multiplied by weighted selection.

After having selected our country using these key factors, we then reviewed if the social impact the telecom base

station would have on Kenya. Through research we determined that the telecom base station would be well

received by the people Kenya and would prove to be useful in their growing economy. It would not be a

difficulty for the people to adjust to the new technology as similar technology already exists in Kenya. The technology would be beneficial to their economy especially because

tourism is a large business and it would provide the people of Kenya a way to communicate and contact each other.
