5G is moving faster and the journey to 5G continues to live up to its name as India takes the lead in the development and implementation of 5G infrastructure with the Make in India initiative. Whi­le the next-gen networks are yet to en­chant mass audiences or sufficiently enthuse early adopters, 5G is on its way to meet the aspirations of consumers and enterprises. This trend will accelerate further as operators and enterprises explore ev­ery advantage. Also, communication ser­vice providers (CSPs), device makers and network equipment manufacturers are realising that they need to develop new processes, adopt new technologies and adapt to change. As CSPs and network eq­uipment manufacturers (NEMs) continue to find themselves traversing new terrain, they recognise that they must seek help in areas where they are not experts and dedicate important resour­ces in only those areas where they can confidently take the best-in-class app­roach. The key goal is to keep costs down and be­come as efficient as possible.

Private 5G networks to multiply

Operators see opportunity in providing 5G private networks to large enterprises for mission-critical applications. Enterpri­ses perceive 5G as desirable, and even hi­ghly important, but they are yet to be convinced if it is mature enough for business-critical functions. The trend driving private 5G networks is enterprise digitalisation strategies advanced by 5G and Wi-Fi 6 convergence, the need to capitalise on br­eakthrough technologies across internet of things (IoT), big data analytics and in­telligent automation.

Open RAN adoption to accelerate

As communication service providers chase spe­cific efficiencies, performance and ca­pa­bilities, open radio access network (RAN) will create an expanded ecosystem of interchangeable RAN vendors, lowering cost and barrier of integrating innovative product development while accelerating innovation. Test and assurance will be cri­tical for this open ecosystem.

New approach to service assurance

5G changes everything for service assurance. New multivendor networks are high volume and dynamic, where traffic is almost always encrypted and it is impossible to align with traditional tools and outdated strategies. With a new class of disaggregated and cloud-native infrastructure, the approach to service assurance must be as evolutionary as the network itself. CSPs require a simpler, guided solution that can deliver end-to-end visibility, give actionable insights and perform automated troubleshooting on any network infrastructure, while empowering operations teams with intuitive data and automated workflows.

Time-sensitive networking evolving fast

Artificial intelligence, advanced automation and augmented/virtual reality are hel­ping accelerate smart manufacturing, ma­king factories more agile and efficient. Ti­me-sensitive networking (TSN) is the te­chnology of the future for convergent in­dustrial communications and Industry 4.0. Interworking of the 5G system and the TSN system is key in making the 5G sy­stem a better fit for future industrial internet of things (IIoT) applications.

Automation will find broad adoption

Network equipment vendors, communication service providers, multiple system op­erators and enterprises are all focused on improving agility and operati­onal efficiency. Automation will enable use cases such as new service activation, continuous monitoring and automated troubleshooting seamlessly integrated with network management systems.

End-to-end testing is vital

Network operations teams are recognising that legacy visibility models are simply inadequate in cloud-native, highly disaggregated and fully virtualised network en­vironments. With new service delivery mo­dels becoming essential for successful 5G deployments, testing individual Open RAN infrastructure components is no lon­g­er feasible. There are also fundamental changes in how new services such as 5G, multi-access edge computing (MEC), software defined wide area network (SD-WAN), secure access service edge (SASE) and O-RAN are being developed, deploy­ed and optimised for market consumption. True end-to-end testing and assurance, fr­om a user device through to the core network across all layers (physical, transport, network, service), is highly imperative.

Benchmarking and field testing, cloud infrastructure validation, security tests and isolation of application and network issues represent the most pressing needs. The upcoming picture tells us that the 5G journey is multifaceted and multidimensional. It will require the right partnerships, pa­ti­ence and perseverance, and above all, it will demand persistence and commitment
