A complete autonomous system consisting of a beam steerable Hemispherical Square Loop Antenna (HSLA) controlled by a Raspberry Pi is presented for optimizing the throughput in a scattered and a poor Signal to Noise Ratio (SNR) environment. A total of four different indoor communication configurations at various distances were analyzed in presence of interferences. In three configurations HSLA performance was also compared to that of a standard monopole antenna link. It was found HSLA can offer up to 1450 % higher throughput and can withstand much higher interference levels before the system breaks. In terms of quality this means sustaining compressed HD communications. In effect, it improves the system throughput for the test 2.4 GHz (802.11b/g/n) WiFi band. The uniqueness about the system is that it only uses single antenna for both sensing and communication. The algorithm works at application layer that controls the RF switch and antenna patterns at physical layer. Thus, the entire middle protocol layers are untouched. The system can easily be retrofitted to existing non-adaptive communication systems.
The PI made a substantial contribution to the conception and design, led the work and helped to draft / to redraft the output for important intellectual content.
