Abstract

In a world where ubiquitous connectivity became more of a necessity then luxury sparsely populated and rural areas remain the least connected areal around the globe. Considering conventional wired or wireless infrastructure will cost billions to implement and maintain. A very attractive solution that has proven improved performante in terms of signal quality, coverage area and connection speed consists of using an adaptive smart antenna system in conjunction with IEEE 802.16 WIMAX [1]. This paper presents the design and development of a testbed to analyze the feasibility of utillzing such novel solution. Though supported by the WaMAX standard, a smart antenna system utllizing this radio technology has not been implemented yet. This design serves as a common flexible platform for testing the system as a whole and in part. The different system's modules, namely, the Direction or Arrival (DOA) estimation module, the beamforming module and the computer interface have been tested and showed promising results.
