This paper presents a cost-effective high-speed multimedia- content download system using a hybrid wireless link consisting of a 60-GHz (mmWave) link and a conventional wireless link, such as IEEE 802.11. The capability gap between the components of existing systems and a mmWave link caps system-level performance and degrades resource utilization. We developed an FPGA-based prototype system to investigate system-level performance for well balanced systems. Our performance evaluation involved changing the PHY parameters, data acknowledgement (ACK) methods and link quality. Under the point-to-point network, our results confirmed that a hybrid system with a unidirectional mmWave link using software burst ACK and well optimized packet and burst sizes can achieve competitive performance.
