It must also support the various needs of parallel network architectures and technologies, and seamlessly support the coordination between many more cell sites, including those that will coexist with 4G technology for many years to come. This demands a new approach to radio access network RAN architecture and the underlying transport network. Traditional 2G, 3G and 4G network architectures need to evolve and the radio-near transport network needs to support this evolution.
The sheer number and variety of new 5G-enabled use cases mean transport architectures must also evolve end to end, from access to core. Serving these successfully needs a transport network that can handle not only a huge increase in traffic, but also the wide variety of network characteristics for each specific use case. For example, critical IoT uses cases will demand ultra-low latency connections, while others have more relaxed requirements on latency.
Radio network performance will depend heavily on the ability of the transport network to meet differing needs for capacity, latency and quality of service in a highly flexible, responsive, automated, integrated and cost-efficient way. Operators will need to be able to manage and orchestrate their networks end-to-end — all the way from radio access, through fronthaul and backhaul, to the aggregation and core networks. End-to-end security has never been as high on the agenda as it is in 5G.
Transport networks play a key role in this: secured end-to-end transmission is crucial for many of the new services 5G will cater for. The transport network will also need to support a range of new radio capabilities, including larger spectrum, coordination services and new radio functionality, such as Massive MIMO.
Higher capacities will be required for most 5G fronthaul and backhaul networks, as well as edge and core networks, while coordination services and some radio functionality will demand improved latency. Transport networks designed with a 5G vision will need to evolve in harmony with advanced LTE needs, and enable a smooth transition for network operators from 4G into 5G even as traffic levels rise.
As the part of the network that carries traffic between radio base stations and the core network and data centers, the transport network plays a crucial role in delivering the benefits of LTE Advanced and 5G radio networks: — It must be able to handle ever-more capable user devices and the huge increase in traffic enabled by 5G.
Operators need to address five key transport challenges as they roll out 5G: capacity, connectivity, capability, complexity and cost. Capacity Higher traffic demands from subscribers in the radio access network translate into higher traffic demand in the transport network — overall throughput increases and throughput per site increases.
High backhaul demand drives the need for access to more fiber or new spectrum and more efficient techniques for microwave transmission. As peak user connection speeds rise above gigabit-per-second levels, Ericsson predicts a global average five-fold increase in traffic volume by , with even faster growth in video traffic, which will constitute 73 per cent of traffic volume by The challenge will be how to right-size the initial deployment and cost-effectively grow to meet added demand.
Connectivity The increasing number of radio sites will drive the number of termination and access points for transport. Densification resulting from the increased bandwidth demands and the deployment of smaller cells using higher-frequency spectrum , will mean a three- to four-fold increase in cell sites in new locations. This will, in turn, demand a high density of high-capacity interfaces. In addition, 5G will introduce a multitude of new interfaces supporting new radio functions.
Furthermore, cloud distribution in the 5G core will mean even more connection points. The shift from LTE to 5G is a game- changer for transport: the increasing traffic volume and the significantly higher capacity demands in radio cells supporting enhanced radio functions, the growing range of services and new business models all require operators to rethink their mobile transport stategies.
Coordinated multi-point transmission will drive the need for inter-site communication with low latency. Since 5G is expected to support a multitude of new use cases, with varying transmission characteristics, virtualization in both the 5G core and 5G transport is key to efficient and dynamic resource utilization.
All these factors imply increased connections, scalability and flexibility in the complete 5G transport network. Capability New capabilities are needed in the 5G transport network to serve new use cases and radio functions such as coordination and MIMO with beamforming. These include low latency and improved synchronization, especially in the fronthaul network. Ever-increasing threat volumes and attack sophistication — including zero-day attacks, advanced, persistent, targeted attacks, and adaptive malware — are driving the need for more robust mobile network security.
With the increases in connectivity, virtualization and disaggregation in 5G, there will be a greater number of connection points and a greater need to adapt to the dynamic nature of service handling. The transport network will require new capabilities that increase agility and flexibility and serve a more distributed mobile network architecture.
Complexity The overall complexity of the transport network will be increased by the number and variety of new use cases, the increased number of connection points, and the co-existence of different radio technologies and architectures. The shift from MBB to multiple services drives the need to support different quality of service requirements.
Deployment of V-RAN, network slicing and distributed cloud will lead to more dynamic traffic patterns and more complex connectivity demands. Cost Complexity always comes with a cost penalty, and this needs to be resolved to make 5G business profitable. In summary, the advances enabled by 5G technology cannot be handled cost- effectively simply by adding more capacity to the existing infrastructure.
The old model of having separate layers of functionality, with physically separate equipment, connected by multiple rigid interfaces, is not sustainable in the 5G world. The transport network needs to become more integrated with the radio access and core parts, and TCO-optimized solutions are needed to manage costs. A fundamental shift in thinking is required: one that breaks the traditional linear relationship between network performance and cost.
Ericsson has thought through the transport challenges operators face as they roll out 1Gbps-plus LTE Advanced and 5G, and has developed a 5G transport portfolio that addresses these transport-specific challenges, in a way that is fully aligned with our radio portfolio. Although transport must evolve end to end to meet the needs of new 5G use cases and efficient resource handling, the transport domain that will the most be affected by the 5G challenges is the radio- near fronthaul and backhaul networks.
Here, the new radio interfaces and functions, as well as increased capacities, will have the biggest impact. New end-to-end demands, which also affect the edge and core parts of the transport network, include capacity, latency, security, scale and slicing.
Network slicing, in particular, is an important technology for future 5G services and it places additional demands on the 5G transport network to enable the hundreds of anticipated 5G use cases. To build an efficient 5G transport network, a complete transport toolbox is needed to meet new RAN requirements and handle the different deployment options in the most scalable, economical and flexible way.
This will contain an extensive fiber and microwave product portfolio which enables operators to deploy the right combination of technologies to serve changing needs most cost-effectively. To ensure flexibility, operators can deploy a combination of fiber and microwave transport technologies: fiber where multiplexing of different services offers cost-efficient and low-latency transmission for fronthaul; microwave where fast, flexible deployment is needed, but still with 5G-ready capacity with low latency over the air.
For network slicing, the transport network needs to be able to offer end-to- end capabilities, including extensive quality of service support, segment routing, Layer 3 VPN services and security. Building a network with best-in-class components does not necessarily deliver a best-in-class result, especially with the added demands on 5G transport. It is especially important to consider how the building blocks are managed to work together most efficiently end to end.
Cross- domain orchestration is needed to deliver network slice awareness and assurance, which ultimately dictates the end-user experience and performance. Our end-to-end 5G transport solution is built to address these challenges, supporting operators in the transformation of their transport networks.
Managing capacity growth Transport capacity needs have grown continuously over time, and will continue to grow with the roll-out of 5G.
In particular, increased spectrum needs, Massive MIMO and increased spectrum efficiency are driving the need for higher backhaul capacity. There is a clear inflection point approaching in capacity growth beyond which current transport architecture will not be able to manage the new load, and transport modernization will become a necessity. For example, 10 Gbps baseband interfaces and cell peak capacities beyond 1 Gbps are placing new requirements on transport equipment. New 10 Gbps interfaces are needed on cell site devices with higher switching capacities, while Gbps speeds and beyond are required higher up in the backhaul and in the aggregation network.
The high-capacity sites serve the majority of consumers in urban and dense urban areas, meaning they will have the most urgent need for transport capacity. By , the expected D-RAN backhaul capacity at these sites will be around 3—5 Gbps, while the coverage-optimized sites are expected to require around Mbps. Fulfilling these requirements in the most flexible and efficient way will likely demand a combination of fiber and microwave transmission in the backhaul domain.
For microwave, E-Band will become more widely used as a stand-alone solution for 10 Gbps, as will mulitband solutions together with the traditional frequency bands. In densely populated and high-traffic locations, moving from the traditional distributed D-RAN to centralized C-RAN radio architecture will help operators achieve the best balance of radio performance and coverage, service quality cost-efficiency.
Baseband centralization requires fronthauling, meaning this interface will also be affected by capacity growth in radio. Massive MIMO is driving a shift from CPRI to packet-based eCPRI, which can reduce traffic volume on fronthaul connections by as much as 75 percent, helping to manage the growth in data traffic as the number of antenna elements increases.
Capacity demands in 5G core networks will follow those in backhaul networks. In the near- or mid-term, however, such capacity demands are expected to be moderate where 5G is deployed in co-existence with established 4G networks. Building an efficient 5G transport requires a broad set of equipment in terms of a complete toolbox: purpose- built products for 5G radio, offering flexibility in transmission technologies and a set of capabilities to support best-in-class radio performance.
