Key Differences between Fronthaul, Backhaul, and Midhaul in 5G Networks

Fronthaul connects the Radio Unit to the Baseband Unit, requiring high-speed, low-latency links to support real-time data processing and advanced 5G features. This connection is typically established using high-speed, low-latency fiber optic cables, ensuring that the large amounts of data generated by the RU are transmitted efficiently to the BBU for processing

Backhaul connects the Baseband Unit to the core network, ensuring reliable and efficient data transfer across the broader network infrastructure. This connection can be established using various technologies, including fiber optics, microwave, and millimeter-wave links. The backhaul network is responsible for carrying aggregated data traffic from multiple cell sites to the core network.

Midhaul connects the Centralized Unit to the Distributed Unit using cost-effective commercial hardware, providing a flexible and scalable approach to network deployment. Midhaul is a relatively new concept introduced with the advent of 5G networks, bridging the gap between the Centralized Unit (CU) and the Distributed Unit (DU).

✔ Understanding the distinctions between fronthaul, backhaul, and midhaul is essential for the design and optimization of 5G networks, as each segment plays a critical role in ensuring the overall performance, efficiency, and reliability of the network.
