Connect anything, anyone, anywhere with anyhaul mobile transport
How can Nokia mobile backhaul and fronthaul networks help you to keep up with demand?
Mobile data growth and the increasing need for connectivity are compelling operators to further densify, centralize and cloudify their networks to keep up with capacity demand from high-resolution video, immersive communications, cloud services and connectivity for IoT/M2M devices.
Our Optical Anyhaul solution helps you cope with data growth. It allows your transport network to cost-effectively scale and reach more endpoints, so you can densify your network with more cells for greater capacity and coverage. Supporting a flexible mix of distributed and centralized radio access network (C-RAN) architectures, Optical Anyhaul delivers the capacity, ultra-low latency, and highly accurate synchronization distribution needed to boost RAN performance and take advantage of virtualized network resources.
Why are mobile backhaul and fronthaul key ingredients to getting the most out of your RAN?
To better address mobile broadband traffic growth, 5G RANs use new spectrum bands to increase RF capacity, rely on new functional splits that allow for the disaggregation of base station components, and leverage new packet-based interfaces that increase transport efficiency and help to lower cost. And with 5G, the agility of cloud architectures leverages network slices to deliver flexible and efficient broadband services to consumers and vertical industries.
To take advantage of these mobile innovations, Nokia optical transport networks offer highly scalable bandwidth growth through a resilient, programmable network with switching at the packet and photonic layers to optimize resources and improve service assurance. They deliver low-latency connectivity via a deterministic, time-sensitive network (TSN) and support a flexible mix of protocols enabling traffic convergence. This includes the packetization of CPRI/OBSAI flows, which improves bandwidth efficiency while avoiding the need to retrofit existing radios.

Mobile transport for all deployment scenarios
Our proven, TSN packet-optical and WDM mobile transport solutions get you up and running fast. They are purpose-built for indoor and outdoor deployment environments and for sites constrained by space and power — with the ability to easily connect any RAN generation and any protocol at any location (indoor and outdoor) to help you maximize your network investments.
Fronthaul for C-RAN
Our purpose-built Optical Anyhaul solution provides you with cost-effective connectivity by optimizing fiber efficiency through a mix of packet and WDM aggregation capabilities. It transports any mix of protocols (CPRI/OBSAI/eCPRI/Ethernet), allowing you to maximize your investments across multiple RAN generations.
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. It uses our proven Nokia 1830 product family, including our IEEE 802.1CM-compliant TSN switches to create a highly flexible, scalable, and power-efficient solution that you can easily and quickly deploy in diverse environments.
Addressing the installed base of CPRI/OBSAI radios
Our TSN switches won’t leave your existing CPRI/OBSAI radios stranded. They enable a smooth transition to 5G while improving interworking and bandwidth efficiency without the need to retrofit existing CPRI/OBSAI radios. By mapping CPRI radio streams to packet, they can be aggregated with other packetized traffic to improve bandwidth efficiency.
Importance of Radio over Ethernet for 5G
Multiservice aggregation for mobile anyhaul
As part of the Optical Anyhaul solution, our Nokia 1830 product family leverages integrated Layer 2 packet transport and switching capabilities, enabling the aggregation of different traffic streams and improving traffic efficiency. These streams include mobile backhaul, enterprise and residential broadband flows. They leverage the power and value of the Nokia Service Router Operating System (SR OS) to enable a fully managed packet solution with a common service, operations and management model across the Nokia optical and IP/MPLS/Ethernet portfolio, resulting in a more comprehensive and efficient solution.
High-precision timing and synchronization distribution
Synchronization is the lifeblood of your RAN, since without it your network cannot function. With 5G networks requiring frequency, phase and time synchronization and as clock specifications become more stringent, particularly in fronthaul connected sites, there is a growing need to back up Global Navigation Satellite System (GNSS) synchronization with a network-based synchronization source to ensure uninterrupted operations.
Nokia packet-optical transport networks can distribute highly accurate synchronization data to cell sites either in-band (synchronization provided together with traffic) or out-of-band using a dedicated optical timing channel — enabling hard isolation of the synchronization plane and eliminating the effects of dynamic packet delay variation caused by link- or switching-related asymmetries.
The 1830 Time-sensitive Packet Switch (TPS) and 1830 Photonic Service Switch (PSS) portfolios provide enhanced Synchronization Ethernet-based frequency synchronization and IEEE 1588 PTP-based phase/time synchronization, meeting and exceeding the synchronization performance requirements of ITU-T G.8273.2 telecom boundary clocks and IEEE 802.1CM TSN for fronthaul standards. In addition, the optical portfolio supports new capabilities that aid you in the Sync OAM tasks required to manage the distribution of synchronization in the network.
Transport network slicing
5G brings new revenue opportunities by enabling a plethora of new services, with each service having a unique class of service requirements. Your transport network must address this service diversity by cost-effectively delivering the required performance for each application.
Our packet-optical switches provide transport slices connecting the RAN and core slices as part of the end-to-end network slices. These slices maximize transport resources using logical network instances over a shared network.
Traffic flows are mapped into transport slices supporting performance objectives including capacity, latency, reliability, security, etc. A combination of hard and soft traffic isolation allows you to ensure proper traffic separation with the ability to maximize resources by enabling multi-tier, dynamic elastic bandwidth adjustment.
Fronthaul as a service for wholesale operators
As MNOs move forward with their C-RAN deployments, new opportunities will be created for many competitive fiber providers, colocation providers, tower and other utility providers that offer transport services. While operators can offer dark or lit fiber services, the packet-based eCPRI interface and radio over Ethernet (RoE) traffic allow transport providers to offer more granular packet fronthaul services.
Our packet fronthaul solution based on the 1830 TPS enables the delivery of Fronthaul-as-a-Service (FHaaS), which relieves MNOs from building dedicated transport networks. Instead, transport providers can provide deterministic packet transport, leveraging TSN fronthaul networks to meet the stringent requirements of eCPRI/CPRI transport.
Case study: Operator reduces transport costs with TSN fronthaul
A major North American MNO wanted to unlock the benefits of C-RAN by building high-capacity and low-latency fronthaul links to connect its 5G radios and baseband equipment. The MNO chose a Nokia packet TSN fronthaul solution that enabled it to better scale its network and deliver leading-edge business and consumer services while keeping transport costs in check.
