5G backhaul, initially where operators are focused on to deliver new eMBB services, is essentially the same as in 4G, albeit carrying much more traffic due to higher performance, higher bandwidth 5G New Radios (NRs). Well, video will represent 76% of all mobile traffic by 2025, and guess where most video content is located? Mobile fronthaul involves the movement of data and voice from a cell site Remote Radio Head (RRH) to a centralized Baseband Unit (BBU), which then connects to the Mobile Telephone Switching Office (MTSO). To be able to converge 4G fronthaul and backhaul traffic alongside 5G fronthaul, midhaul, and backhaul traffic onto a network means supporting multiple 4G and 5G interfaces, such as the 4G CPRI, 4G Radio-over-Ethernet (RoE) encapsulation, 5G evolved CPRI (eCPRI), O-RAN Fronthaul, and O-RAN Open F1 interface profile.

Ciena recently announced major additions and enhancements to our 5G Network Solutions, including three new routers optimized for the xHaul transport network, Network Slicing and Dynamic Planning enhancements to our Blue Planet Automation Software, and professional Services to help operators along their unique 4G to 5G journey. With 5G – this can and will change. Ciena is committed to ensuring digital accessibility for people with disabilities. All of this – along with many other factors – drives the need for reliable, scalable and cost effective fronthaul and backhaul. All rights reserved. With help from organizations such as the operator-led O-RAN Alliance, 5G fronthaul and midhaul network interface specifications are open and defined in a structured format. 2.) Do you need support on an existing product? Comments are limited to 1500 characters. There’s a momentous shift happening in the industry with a move to break open 4G fronthaul networks. Check out the other two blogs in this series on the midhaul and backhaul parts of the wireline network that are also critical to 5G supporting the guaranteed end-to-end network slices that will unleash a new wave of exciting new eMBB, mMTC, and urLLC applications and use-cases. Filipinos believe that the most critical use cases for 5G will be virtual business collaboration... Decision makers see 5G having biggest impact on corporate applications and virtual collaboration. Brian Lavallée explains in part 1 of a 3-part series on xHaul networks. September 16, 2020 . Ciena proactively believes in openness and that’s why we introduced our new, multi-vendor interoperable 5164, 5166, and 5168 Routers – to help MNOs break free from vendor lock-in once and for all. 5G looms over the network strategies of mobile operators, as does the ongoing move toward CRAN, SDN and NFV. Ciena is playing a key role in India’s 5G ecosystem. Mobile Fronthaul is the movement of data and voice from a cell site to a baseband unit. Let’s focus on the fronthaul capabilities of the 5168 router and its numerous fronthaul interfaces, which make it different from the 5164 and 5166 routers. The optical links that connect the BBU to multiple RRHs is referred to as Mobile Fronthaul. #CienaLife: A place where you can belong. I agree to subscribe to Ciena's communications. Just as service providers seek to leverage best-in-breed technologies to design and build the highest performance networks for their users, at Ciena we’re always looking for opportunities to offer value added programmability to further increase the capabilities and performance of our solutions. Chris Page. The time is now to open the RAN As an industry, the time is now to ensure that the emerging midhaul network will be open and standards-based, lest we fall back into a similar closed and propriety era that is the case with CPRI-based fronthaul. The Case for Using PON for 5G Fronthaul. Our 5G connectivity portfolio comprises packet and optical solutions targeted at converged 4G/5G fronthaul/midhaul for digital radio transport over standards-based new L3 IP support for intercell connectivity. Designed for high performance, the solution addresses stringent 4G/5G fronthaul requirements by supporting high capacity, ultra-low latency transport while delivering highly accurate synchronization distribution to ensure optimal RAN performance. 1000Base-SX/LX Ethernet (IEEE 802.3-2002, clause 38), 10GBase-LX4 Ethernet (IEEE 802.3-2005, clause 53), Fibre Channel (FC-PI-4, INCITS revision 8), Infiniband (volume 2, release 1.1, November 2002), 10GBase-S/L/E 10G Ethernet (IEEE 802.3-2008, clause 52). Why multi-vendor interoperable xHaul networks? 3.) With a mobile fronthaul network in place, providers can take advantage of Optical Transport Network (OTN) technology to move data from the cell sites to the BBUs. Intel’s Field Programmable Gate Array (FPGA) technology provides the required performance, flexibility, and programmability we need to implement multiple fronthaul specifications today. Dazu gehören drei neue, für das xHaul-Transportnetz optimierte Router, Verbesserungen im Bereich Network Slicing und Dynamic Planning der Blue Planet Automatisierungssoftware sowie professionelle Services zur Unterstützung der Betreiber bei ihrem … You have subscribed successfully. Do you want to learn more about Ciena's products? MNOs were forced to buy RRHs and BBUs from the same vendor and to transport fronthaul traffic over costly, and often unavailable, dark fiber due to CPRI’s very high (and inefficient) capacity and stringent latency requirements. This technology has a number of key advantages, including: Reduction in transport costs: Transporting multiple clients on a single wavelength, while preserving their specific requirements, reduces the overall cost of transport … All rights reserved. In the next five years, driven by a need to get data and applications closer to end-users, both humans and machines, tens of thousands of additional scaled-down data centers will sprout up at the edge of the network to form the Edge Cloud. 2Q20 Transport Customer Markets Report. It defines a footprint-optimized solution for transporting 400Gb Ethernet over DCI links targeting a minimum of 80 km. Figure 1: High-level 4G C-RAN vs. 5G C-RAN architecture. Ciena is committed to ensuring digital accessibility for people with disabilities. Ciena’s 5G Network Solutions are built upon proven professional services and an open, automated and flexible architecture, enabling Ciena to partner … LightCounting has published a Research Note titled “Mobile Fronthaul in the 5G Era” 4G fronthaul has converged on 10Gbps optics. The best way to cost-effectively do so, is through an open, interoperable, and converged transport network that unifies fronthaul, midhaul, and backhaul over a common transport network infrastructure. Let me explain. 5G Mobile. Ciena’s services team works with operators from initial strategy consultation through to implementation and ongoing maintenance to ensure success along all stages of the 4G to 5G journey. This allows MNOs to purchase RUs, DUs, CUs, and the associated transport networks between them, from anyone, as long as the equipment complies with the O-RAN specifications. How is Ciena contributing to the Indian 5G ecosystem? Unlike its predecessors, 5G includes upgrades to the wired infrastructure. Ciena’s three new routers support the open 5G fronthaul and midhaul network interface specifications being developed by organizations such as the operator-led O-RAN Alliance.
