With 5G, Mobile network operators can offer new high-value services and enter new markets, but they need a next generation transport network
With the introduction of 5G, Mobile Network Operators have an opportunity to become Universal Service Providers, offering a complete range of telecom services. This requires a serious re-think into the way mobile networks are designed, architecture, managed, and optimized.
Today’s 5G rollout is focused on providing broadband services; with enhanced mobile broadband (eMBB) provided to mobile devices and fixed wireless access (FWA) to homes with poor fixed access connectivity. As mobile networks operators move from initial deployments to mass country-wide coverage, with new services, they will need to invest heavily on new 5G infrastructure. But where are they with the business case?
With 5G, for the first time, the connectivity fabric has the potential to create differentiation for network operators. Enabling them for the first time to transform from CSPs to DSPs (Digital Service Providers). Achieving this differentiation will require many changes in network architecture.

While the term “network slicing” typically brings up an association with 5G technology and services, they are not directly related. Network slicing simply is the ability for to carve out multiple virtual networks, with significantly different performance characteristics, from a common physical infrastructure. Here’s what you need to know about network slicing technologies:
5G networks require a new breed of transport technologies, providing high transport capacity, and adhering to stringent timing, latency and synchronization criteria. Compared to legacy technologies, 5G transport is also more diverse and flexible
Wholesale and open-access business models for fiber and network-infrastructure providers are not new. However, up till now there has been very limited emphasis on delivering newer and more innovative models for wholesale backhaul. 5G is set to disrupt the historical status quo. In other words 5G will open up a whole new world of opportunities for wholesale backhaul.
However, achieving fiber connectivity is just the first step. The next, more complicated, step is deciding how to best monetize the investment in this fiber infrastructure.
There are many challenges that must be solved in creating a transport network for 5G. These involve new transport and architectures and new technologies like network slicing and FlexE
AI use cases apply to both legacy and 5G networks. It is a key element in 5G network service delivery, enabling 5G networks to support technologies such as network slicing, edge computing, and network virtualization at scale.
