In this paper we study the application of Diversity Coding to enable near-instantaneous recovery from link failures in 5G wireless Cloud Radio Access Network (C-RAN) networks. We focus on networks where remote radio heads in a C-RAN are connected to the baseband unit in two hierarchical tiers with optical and wireless fronthaul links. In order to avoid retransmissions and re-routing delays due to link failures in wireless links, we investigate the use Diversity Coding where a feed-forward network design uses forward error control across spatially diverse paths to enable reliable networking with minimal delay.
