N2 - We consider an ultra-dense wireless network with multiple sources and multiple relays which forward quantized signals via some fronthaul network to some destination point. We discuss the loss of information at the relays due to the quantization process, and the trade-off between this loss and the load on the fronthaul network. We consider the application of a modulo operation to reduce the cardinality of the quantized signals, and point out the relationship of this approach to Wyner-Ziv coding and compute-and-forward.
