In today’s rapidly changing digital age, low-latency, high-bandwidth 5G will undoubtedly become a factor that will change the times. However, when planning and implementing this huge investment plan, service providers must be smart and effective.
NETSCOUT made the following predictions for the 5G trend of 2019 to help you quickly understand the development of the 5G era.
Prediction 1: 5G will promote the development of virtualization technology in 2019
People are increasingly calling for 5G, and many countries are actively deploying this strategy and launching commercial 5G networks. The world’s major markets are conducting 5G trials, and major mobile phone manufacturers are also gearing up to make 5G mobile phones a fist product.
China’s three major operators have also defined the 5G timetable, and plans to achieve commercial scale of 10,000 stations by 2020.
People have high expectations for 5G, seeing it as the next-generation mobile communication standard, and will determine key processes and innovations for tasks such as telemedicine, telesurgery and even autopilot.
However, before these become a reality, the construction of network infrastructure will require a lot of money, and mobile and fixed network operators are expected to pay for it.
In fact, many of the above 5G use cases have not yet been determined, so operators can only bet on uncertain futures.
So what is the future of 5G? What do I need to implement 5G?
One thing is certain – 5G will promote the development of network virtualization. In 2019, we will see more and more operators commit to deploying virtual network infrastructure to support 5G applications and services. Without virtualization, it is impossible to implement 5G. This is because 5G requires not only a virtual core network, but also a virtual edge network, and the latter is crucial. In addition, we have established a network that supports a single use case (such as mobile voice and data or home broadband). If 5G becomes a reality, in the future, we need to build an intelligent automation network that can switch between different functions. Support for a large number of use cases.
Prediction 2: 5G can’t “accommodate” itself
In order to support 5G, the virtualized network architecture was quickly applied in 2019, and we expect to see the container become the actual platform for running new applications and workloads.
As we hear more and more news about 5G network deployments, trials and mobile phones, our expectations for 5G are growing. However, there is still no answer to a 5G-related question. What is the form of 5G software and applications? At the same time, how to deploy these new services and applications to the network.
In addition, unlike the 4G mobile broadband network infrastructure, the architecture supporting 5G is virtualized and cloud-based. Therefore, to promote the development of 5G, the wise investment targets are application developers, mobile operators and equipment supply using microservices. Business, as well as the service provider of the container.
Using containers to support 5G makes sense because they provide operators with a flexible and easy-to-use platform to build, test, and deploy applications that are now also more secure.
The current 5G use case has not yet been determined, which is critical for developing 5G services. Operators will need to be prepared to launch services on demand to support different use cases, and the use of containers can provide customers with fast and efficient service.
Prediction 3: Operators must handle 5G security issues in 2019
The advantages of 5G are clear: the new communication standards will provide operators and their enterprise customers with faster network speeds and better performance, ultra-low latency and higher efficiency.
When operators conduct 5G trials and deploy 5G networks, they tend to focus on only 5G to achieve higher network speeds, and less attention to security issues. Everything will change in 2019, and 5G security will become an important issue facing the industry and will be widely discussed.
As of now, network development does not seem to pay much attention to 5G security, but as a problem that can be considered afterwards.
But behind this, operators are actually taking this issue very seriously. The situation of operators has completely changed, because the attack surface in the 5G field has increased significantly, and malicious attackers have more opportunities to exploit the vulnerability to launch attacks.
This is because the adoption of a virtual network infrastructure will allow operators to scale to meet 5G requirements. In addition, operators will deploy 5G networks to support a large number of industrial and commercial use cases, which is why the attack surface is increasing. This means that from now on, operators must not only handle large amounts of sensitive data, but also manage mission-critical systems and devices. In the 5G environment, the safety issues of smart factories, automated production lines and autonomous fleets will be widely recognized. The network security risk has suddenly increased a lot.
Prediction 4: Operators must expand to meet 5G requirements in 2019
5G will be faster, smarter, and more efficient than 4G, but to meet demand and support new architectures, the network must scale. While most of the expansion of the core network is based on cloud and software, the hardware and devices at the edge of the network still need to scale, and there will be more devices in the 5G environment.
In fact, in order to support higher frequency broadband for wireless transmission of 5G data, the number of core websites will increase significantly. At this point, the network management tool will highlight its importance. In 2019, we will see an automated network deployment driven by virtual machines and artificial intelligence.
Network automation and orchestration are “by-products” of virtualization that make problems more complex, but they are also an essential part of the generation and continued development of 5G networks, especially as network topologies will change to accommodate small and large cellular base stations. In particular, small cell base stations, which will form a large number of new RANs (wireless local area networks), are expected to triple the number of cellular networks.
If network engineers think that they have enough problems to deal with when maintaining 4G mobile broadband networks, they may be surprised by the increasing popularity of 5G networks. In fact, if these more complex and extensive networks are not fully understood, the RAN network in the 5G era will become extremely difficult to manage
