ABSTRACT
Wi-Fi signals are susceptible to signal loss as they travel hence Wi-Fi users are rarely completely satisfied with the signal strength offered by the off-the-shelf Wi-Fi cards, routers and access points. This project research intends to introduce a device which can provide Wi-Fi users with high signal strength and at a lower cost in order to enable them have a seamless, uninterrupted and reliable communication. This project includes the steps for Biquad antenna construction, steps for the construction of a Wi-Fi booster circuit and the working of the Wi-Fi booster system as a whole. This project includes in its beginning chapter an introduction into what an antenna booster is and its applications. Also the aims and objectives of the project and the scope of the project are discussed in this chapter. The succeeding chapter looks at the history of Wi-Fi antenna boosters and their various types. Chapter three of this project describes the equipments and software used for the construction process of both the biquad and the booster circuit. Chapter four of this project describes the testing and operation of the system as a whole. The last chapter of this project gives a conclusion of the research carried out, problems encountered and recommendation.
