The use of commercial MIMO APs in RoF-DAS results in substantial throughput reduction. Efficient use of multi-antenna scheme algorithms allows for significant physical separation between the radio units, which results in decreased error rates and increased capacity. MIMO wireless communications in a DAS, which utilizes RoF to increase the overall wireless coverage and capacity have been the focus of this thesis. The main goal is to explore the factors that contribute to throughput declines in an RFDAS when commercial MIMO APs are utilized. Practical challenges are considered to examine the RoF-DAS. Single and multiple-use experience is taken for finding the experimental setup. The investigation revealed that the amount of data the system can transmit correlates with the imbalance in the received power, and the imbalance in the received power correlates with the amount of data the system can transmit.
