Abstract
Availability and sustainability of the internet is required for the deployment of technical, vocational education and training (TVET). GSM and Wifi are the popular technologies deployed for internet provision. These technologies transmit radio frequency (RF) signals. RF signals passing through a non-transparent medium to a free zone experiences penetration loss, which weakens the strength of the signal. A renowned type of this penetration loss is the building material penetration loss. In this paper, a system that enhances RF signal reception is presented. Two types of dipole antennae, for transmission and reception, were designed. The receiving antenna picks up the transmitted RF signal from source. It also incorporates an amplifying circuit built on a LM386 IC. The transmitting antenna radiates the enhanced RF signal to the users. The system output was tested with a RF Signal Speed Detector Application Software. The signal strength of the enhanced RF signal was improved when compared with the non-enhanced signal, improvements over the four identified locations are 37.5%, 65.6%, 78.78% and 164.7% respectively.
