Reliable Data Transmission over Simple Wireless Channels: A Case Study

We discuss the issue of reliable transmission of bounded streams of data samples over simple wireless channels offered by low-end RF modules. Traditional solutions, i.e., window-based ARQ schemes, applied to such channels tend to waste bandwidth, because of the need to maintain duplex communication. Our case study shows how one can overcome the inherent limitations of low-bandwidth unstructured wireless channels and claim most of their capacity for transmitting useful data.
