While 5G use cases are emerging and many are in trials, the big winners are years away from being determined. When they do emerge – without warning and on a large scale, as we saw with Pokémon Go – the network will need to be ready. Effective IP anyhaul solutions can help operators take on anything the 5G future brings.
Operators must start preparing their mobile transport networks now, while 5G radio standards and architectures are still being hammered out. Mobile transport technologies – including fiber, microwave, and GPON – cost-effectively address different geographical constraints. On top of these, IP/MPLS routing is essential to support future 4G and 5G applications.
5 key considerations to get your IP network 5G-ready
1. Support a wide variety of network architectures
Various RAN architectures are currently being explored as the industry tries to find the optimal balance between processing at cell sites and centralized hubs. At the same time, solutions are being developed to push content and some elements of core processing closer to users.
Operators will ultimately use a variety of architectures for 5G. IP routing provides the interconnectivity, scale, timing, and security required for dynamic, any-to-any networking. High-throughput IP routers with a variety of 1/10/100 GE, TDM, and SONET/SDH interfaces will enable operators to get the best fit in any situation.
2. Accommodate traffic growth
When 5G arrives, user data rates will be up to 100 times higher than they are today. Peak data rates will be up to 50 times higher. There will be up to 100 times more connections and 1,000 times more traffic volume per square kilometer. Operators need 10 Gb/s cell site and 100 Gb/s network links, multi-terabit throughput capacity, and high port densities to support this growth.
3. Provide low-latency transport for delay-sensitive applications, while efficiently handling internet traffic
Low latency is essential for centralized and cloud-optimized RAN architectures – where next-generation fronthaul interfaces (NGFI) will be used – as well as a broad array of mission-critical and industrial applications. On the other hand, bursty traffic from traditional internet applications demands deep buffers for optimal performance and network efficiency. To accommodate diverse service requirements, IP anyhaul networks must gracefully address the full scope of applications, delivering low latency where required and buffering where appropriate.
4. End-to-end service management across any topology
Operators’ 5G networks will include more access points, any-to-any network topologies, or virtual and cloud-based network functions. To provide flawless user experiences, operators need end-to-end service management capabilities that minimize OPEX, while making it easier to design and deploy new services.
5. Protect investment
Operators need to minimize CAPEX, while ensuring that they have enough capacity to meet future demands. 5G IP network upgrades must also interwork with existing systems to maximize their useful life.
To satisfy customer needs in a 5G world, operators must deploy a flexible, high-capacity IP anyhaul solution before evolving the RAN or upgrading the core network. Those who choose to deploy Nokia IP Anyhaul solutions can rest assured that their investment will safely accommodate future growth and fulfill all 5 considerations.
