dc.description.abstractIn recent years there has been an escalation in energy consumption in cellular telecommunication systems and wireless communications in general. It has been elaborated in this work that the energy bill amounts to 18% of the total expenditure of operation in matured European markets. The figure is even higher (above 30%) in Tanzania and other developing countries where there are many off-grid base stations or unstable commercial power necessitating the use of diesel generators for power generation at the base station sites. Besides more efficient network designs such as feeder-less solutions, infrastructure sharing, locating base stations close to mobile stations, the use of outdoor base stations, the use of renewable energy and cooperative device to device communication; energy consumption reduction at base stations yield more associated advantages such as reduction in the OPEX and improving life of network equipments. For this rationale, a low traffic shutdown scheme has been developed in this research work taking advantage of extremely low traffic during night periods from 00:00 hrs to 06:00 hrs to shut down some resources at the base station in order to save energy. It has been demonstrated that an energy saving of up to 16.3% on dense metropolitan areas can be achieved. This translated to about 328,936.61 TZS of cost saved per day when this scheme was applied on one cluster of 105 sites in the city of Dar es Salaam, Tanzania.en_US
