‌The Communication and Computing Systems Lab (CCSL) at KAUST is led by Professor Ahmed Eltawil. The research focus of the group lies in the area of efficient architectures for mobile computing and communications systems.  Our philosophy is to employ a multidisciplinary approach to the design and development of  mobile systems spanning algorithm, architecture and implementation. The goal is to simultaneously address two seemingly diverging trends. The first trend is concerned with efficient, high data rate broadband wireless systems driven by continuously expanding networking applications. The second trend, is related to lower bit rate, ultra low power applications, which are finding numerous applications in the context of the internet of things (IoT) such as remote wireless sensing, wearable electronics, sensors etc.  At CCSL, our program is architected to identify and research technologies that provide the foundation on which ground breaking innovations capable of serving this wide spectrum of challenges can be conceived, designed and tested.
