Providing critical links for fronthaul, midhaul, and backhaul connectivity

XHaul includes:

Backhaul: This is the connection between the CU (or DU, depending on architecture) and the core network, typically leading to data centres or central offices. Backhaul has been a core component of mobile networks for a long time, traditionally using fibre, microwave, or millimetre-wave technologies.

Fronthaul: This segment connects the Radio Unit (RU) (such as antennas) to the Baseband Unit (BBU). Fronthaul is used in distributed and centralised Radio Access Network (RAN) architectures, especially in 5G and 4G LTE networks. In traditional networks, this communication was typically handled through dedicated fibre connections. However, newer, more flexible solutions like eCPRI and NGFI are emerging for lower latency and higher capacity.

Midhaul: This refers to the connection between the BBU and the Distributed Unit (DU) or Centralised Unit (CU) in a virtualised or disaggregated RAN architecture. Midhaul is increasingly important in 5G due to network function virtualisation and centralisation, offering flexibility in deployment while ensuring low latency and high performance.t will reshape how we interact with the world around us. However, it’s expected that 6G will likely become mainstream around 2030.

Filtronic’s fronthaul, midhaul and backhaul solutions:

As a leading designer and manufacturer of RF (Radio Frequency), microwave, and millimetre-wave products, Filtronic’s solutions for wireless network infrastructure, include fronthaul, midhaul, and backhaul components for 5G and other advanced networks. Our product portfolio supports high-capacity, low-latency data transport across all segments of the XHaul network. 

Fronthaul solutions

Filtronic offers a range of high-frequency, high-performance transceivers and components for fronthaul, particularly focusing on millimetre-wave (mmWave) technologies like E-band (71-86 GHz). These are critical for 5G deployments that require higher throughput and lower latency.

• E-band transceivers: Filtronic specialises in E-band transceivers which offer ultra-high capacity (multi-gigabit per second) wireless links with reduced latency and improved spectrum efficiency. Our products enable reliable fronthaul communication for 5G base stations in dense urban environments where fibre deployment is impractical.
• Low-latency performance: Filtronic’s fronthaul solutions are designed to support low-latency and high-bandwidth requirements necessary for applications like massive MIMO and advanced 5G services.

Midhaul solutions

Midhaul often bridges the gap between fronthaul and backhaul, requiring flexible, scalable, and reliable transport solutions. Filtronic’s midhaul solutions focus on offering scalable, high-performance wireless links for midhaul applications.

• Point-to-Point microwave and millimetre-wave links: Filtronic offers mmWave and microwave products that are suitable for midhaul networks where high data throughput is necessary but fibre infrastructure is limited. The use of high-frequency bands (like E-band) supports these high-throughput requirements.
• Modular and scalable design: Filtronic provides modular solutions that can be tailored to specific network needs, ensuring scalability for operators as our midhaul networks expand alongside 5G deployments.

Backhaul solutions

Backhaul forms a crucial part of any wireless network infrastructure, providing the necessary link between the radio access network and the core network. Filtronic’s backhaul solutions focus on delivering ultra-high capacity wireless backhaul over long distances with minimal latency.

• Millimeter-wave backhaul: Filtronic’s expertise in millimetre-wave technology, especially in E-band and V-band (57-71 GHz), allows us to deliver ultra-high capacity backhaul solutions. These are especially useful for dense urban deployments where small cells are utilised, and demand for data is very high.
• Licensed and unlicensed bands: Filtronic supports both licensed and unlicensed frequency bands, giving operators flexibility in managing spectrum and deployment costs.
• Carrier-grade reliability: Filtronic’s backhaul products are designed to meet carrier-grade performance standards, ensuring high availability and reliability, even in challenging environmental conditions.

Key features of Filtronic’s XHaul solutions:

• Millimetre-wave expertise: Filtronic is a leader in mmWave technology, providing solutions that deliver multi-gigabit data rates required by 5G networks.
• High capacity, low latency: The emphasis on high-frequency bands like E-band and V-band ensures high-capacity links with the low-latency performance required for modern mobile networks.
• Compact and efficient designs: Our transceivers are designed to be compact, lightweight, and power-efficient, which is critical for small cell deployments and dense urban networks.
• Scalability and flexibility: Our modular products can be adapted to various deployment scenarios, from small-cell backhaul to large-scale macro cell backhaul.
