This technology has generated strong interest in the mobile wireless industry, since IAB is expected to provide a cost-efficient and fast time-to-market backhaul solution.This paper addresses the technology aspects of IAB that are part of the standard, its use cases and deployment considerations, and an overview of IAB-related future evolution research and studies ongoing in the industry.Chris Pearson, President of 5G Americas said, "5G network operators are today faced with an increasing array of choices in designing, architecting, and managing their networks. Since high level coordination of multiple radio elements is not necessary, placing more functionality at the RU location can reduce the bandwidth and latency burden placed on the fronthaul, thereby allowing the CU to be positioned dozens of kilometers from the radio head.Transport Technologies and Testing Strategies for 5G DeploymentFor O-RAN fronthaul, open, virtualized architecture using generic hardware and software will facilitate interoperability among combinations including open distributed units (O-DU) and open radio units (O-RU) from different vendors.

SDN, NFV,MEC and mmWave, find their use too in defining the next generation transport network • The fronthaul is moving from complex and rigid CPRI to more relaxed (backhaul-lean) eCPRI/NGFI. To understand what 5G fronthaul, midhaul and backhaul are, we first need to understand the logical architecture diagram of 5G mobile communication: Mobile Phone-Access Network-Bearer Network-Core Network-Bearer Network-Access Network-Mobile Phone. Heavy Lifting Analyst Notes Sterling Perrin, Principal Analyst, Heavy Reading 5/2/2018. When you bring together fronthaul and backhaul architecture (as well as midhaul), it …
Operators can now select from a variety of wireless and wireline transport options to address the specific topologies and use cases envisioned for their mobile wireless network." with new functional splits • Fronthauland Backhaul are.
All Rights Reserved.The fifth generation of wireless cellular (“5G”) is driving increasing demands on mobile operator networks, which are faced with the need to improve operational efficiency and reduce the time required to deliver new high-throughput, low-latency network architectures to support emerging use cases. Fronthaul became a necessary addition when the ante for bandwidth and efficiency was raised with LTE and a new link connected centralized baseband units to individual radio heads. 25G BiDi optical transceivers, 50G PAM4 optical transceivers, and low-cost coherent 100G optical transceivers are typical representatives of 5G fronthaul/midhaul/backhaul networks for optical transceivers.
