Performance evaluation of mobile fronthaul optical bandwidth reduction and wireless transmission in Split-PHY processing architecture

The RAN architecture splitting BS functions within PHY layer is prototyped and evaluated to confirm its validity. Experiments show that mobile fronthaul optical bandwidth is reduced by 90% compared to conventional C-RAN maintaining wireless performance.
