What is 5G?

5G is the next generation of mobile networks that will provide much faster data rates, dramatically reduce latency inherent in 4G, and implement network slicing to virtualize a single network, supporting a wide range of new services that are not possible today even on the best mobile networks.
Supports billions of IoT objects such as sensors
Self-driving car support
The strong potential of 5G has spurred the market as carriers are ramping up their investments in test infrastructure and chipmakers are pushing to bring new technologies to consumers.

Although 5G is already undergoing trials today, the obstacle to the development of technological solutions is the lack of ready-made standards. The original standards will be transferred to key industry actors, then field tested, after which the standard will be finalized for further testing.

Significant changes take time. Almost a decade has passed since the initial concept of 4G was introduced to widespread availability in the US market. While some carriers have said that 5G may hit the market as early as 2018, it is likely that the standard will be widely available between 2020 and 2025.

Such changes require complex regulation. Technologies in mobile infrastructure (including wireless networks connecting towers and mobile devices) will have to be completely reconfigured or reworked to meet 5G requirements. For ordinary users to take advantage of the new technology, new chips and devices will be required.

Ensuring the efficiency of 5G networks will require the same high efficiency of wired networks, which is arguably one of the most important challenges in the lead-up to transformation phase.


is here to help, with our vast experience in wired networking from radio towers to data centers. We know everything connected with them. Mobile infrastructure is already migrating from traditional TDM-based MBH to carrier-grade MBH packet-based Ethernet – in a timely manner, as carrier-grade Ethernet is an ideal carrier for placing 5G traffic across multiple parts of the network as a whole.

In addition, the transition to 5G will be accompanied by the introduction of network function virtualization (NFV) and software-defined networking (SDN). These technologies and services are now being deployed in infrastructure around the world to help adapt and improve wired networks in line with 5G developments.

Cena’s portfolio of products offers a flexible set of carrier-grade Ethernet delivery and aggregation platforms designed to predict the demand for 5G operations. The portfolio includes solutions large and small that help reduce costs and enable rapid deployment with the best OAM tools for proactive service management.

These compatible platforms are MEF certified. They increase the efficiency of deploying, delivering and administering cost-effective 5G services that deliver scalability, reliability, Qu’s, and service management. Together, these service functions significantly speed up and automate the creation and activation of scalable optical and ethernet services.

Cena solutions offer the following benefits.

Scalability. Cena offers wired network operators highly accurate scalability to extremely high capacity. The Cena portfolio of products provides the flexibility and reliability of optical and ethernet networks, and a variety of security mechanisms to simplify preparation and maintenance, while reducing operating costs.
High quality service. Highly efficient Qu’s and traffic management tools, built-in OAM tools ensure predictable and highly reliable service delivery.

Taking into account the feasibility of these scenarios in megalopolises, small towns and villages, it is possible to draw up a generalized network coverage scheme, approximately as in Fig. 34. As you know, the world has either already abandoned 3G networks, or announced plans to turn them off. Therefore, in Figure 3G it is shown with a dashed line. According to the plans of European operators, instead of slow 3G, fast LTE will come to the villages (scenario # 5 in Fig. 29) while maintaining 2G for voice traffic. Suburban coverage will enjoy faster speeds and lower latencies, while metropolitan areas will boast more connections and ultra-fast internet in FR2 coverage locations. As you can see, in the coming years, 5G networks will not replace 4G networks, but are gradually integrating with them, significantly improving the overall state of affairs.

Usually wired and fiber-optic Internet providers come to such places. But 5G FWA will pose a serious threat to this business sector. Indeed, with 5G at FWA, the quality of broadband Internet will not be inferior to fiber optic, and the cost of connection will be beyond competition, since fiber / cable connection, installation work and configuration for each subscriber are excluded. Installing a CPE is as easy as installing a Wi-Fi router and requires almost no maintenance.

Perhaps, as a result, the market for fiber-optic / wired Internet will change greatly, find its specific application, but it will never be as massive as it is today. And on the contrary, according to the forecast of SNS Telecom experts, by 2030 345 million subscribers will be connected via the FWA service via 5G (Fig. 37), and over 90 million subscriber CPE devices will be sold.
