Who can give me a neutral opinion on 5G campus networks?

Bayerische Funknetz GmbH (BAYFU) operates as an independent and neutral consulting and service company. Their many years of experience paired with in-depth specialist knowledge form the basis for being able to advise companies as required.

Why does my company need a 5G campus network?

The industry is facing demanding challenges in terms of digitisation and automation. In contrast to established technologies such as LTE, WiFi, WLAN, LAN, LORAN, Bluetooth etc., 5G technology offers advantages in many areas. Real-time applications, the management of a large number of IoT sensors, the massive data throughput, network security and availability as well as virtualisation offer massive advantages in terms of flexibility, dynamics and individuality. As an infrastructure solution, 5G contributes to the fact that your applications can be processed in a highly agile and customised manner on the basis of technical standards.

When is the right time for 5G?

5G has been officially launched, but is still under development and is expected to be fully available in 2023. This requires that the relevant three releases 15, 16 and 17 have been described and introduced as standard by the 3GPP standardisation body or will be introduced as standard in the near future. The further development from 5G NSA (non stand alone) to 5G SA (stand alone) is also decisive, as a significantly wider range of hardware and software will then be available at reasonable conditions. In the course of 2020 to mid 2021 most manufacturers will have 5G SA components in their portfolio. 5G campus networks can thus be planned and built immediately and adapted step by step to the new requirements and developments.

What are the main advantages of 5G?

- Network access: a wide range of technologies (wireless, wired and optical) work
functionally together.
- Elasticity: 5G is IT. This means that the networks are dynamically configurable. The addition of new sites or the introduction of new processes should be highly automated. Virtualisation means that resources are dynamically provided where they are needed.
- Performance: The so-called network slicing function provides controllable connections with a pre-defined quality for all supported applications.
- Availability: Production-critical applications can be specially protected against production-relevant applications. Availabilities of 99.999 % are possible.
- Security: 5G as part of the IT environment should at least meet the same security standards. Due to the SIM-based authentication mechanisms, the profile management of all users based on them and the network architecture itself, 5G contributes significantly to minimising security risks.
- Scalability: The possibilities of the network architecture and its virtualisation provide the basis for the agile and future-proof integration of new extensions. 5G is the optimal basis for organic growth

Who offers 5G?

There are public 5G networks provided by the incumbent mobile operators. In addition, since 2019 there is the possibility in Germany that companies can build and operate their own mobile networks, completely detached from the mobile operators. These are then the so-called private campus networks. A large number of manufacturers, suppliers and service providers offer products and solutions for implementing private campus networks. It therefore depends on how you want to implement 5G in your company. As TurnKey solutions based on a public 5G mobile network or where you want to become a mobile operator yourself within your private 5G campus network.

How does a 5G campus network work?

A campus network is understood as a geographically limited, local mobile radio network adapted for special requirements such as industrial communication. Both 4G (LTE) and 5G technology can be used here. This flexibility allows the highest quality of service requirements in terms of latency, reliability and availability of the communication networks to be met.

Private LTE / 5G campus networks are also characterised by the fact that they can be operated separately from the public network and thus completely isolated. Highly secure interfaces offer the possibility to create a connection to public networks in order to grant your suppliers controlled access to their applications.

This is made possible through the procurement of dedicated and exclusive radio frequencies from the relevant regulatory authority (e.g. BNetzA). Campus networks can be designed and developed on the basis of technological standards to meet your individual needs. This makes campus networks attractive for applications in various industrial sectors and thus provides the basis for the digital transformation.

What is the difference between WiFi (WLAN), 4G (LTE) and 5G?

 

In which countries can private campus networks be operated?

Many countries around the world offer the possibility of operating private campus networks in addition to public mobile phone networks. These are, for example, Germany, Great Britain, USA etc.

What are the requirements for operating a private campus network?

As a rule, frequencies are allocated by the regulatory authority (e.g. Federal Network Agency) on the basis of an application procedure. Furthermore, the legal provisions regarding the operation of fixed radio installations must be complied with.

What is the difference between a public 5G network and a private campus network?

There are public 5G networks provided by the incumbent mobile operators. In addition, since 2019, companies in Germany have had the possibility to build and operate their own mobile networks completely detached from the mobile operators. These are then the so-called private campus networks.

Is a 5G network more expensive than a WiFi network?

It all depends. A general statement is not possible. Based on the respective application, a comparison at eye level is necessary. It is important here that the same decision parameters are used in each case. As a rule, it can be seen that the TCO is better at 5G in classic applications in an industrial environment.

Who can give me a neutral opinion on 5G Campus Networks?

The Bayerische Funknetz GmbH (BAYFU) acts as an independent and neutral consulting and service company. Its many years of experience combined with a profound expertise form the basis for being able to advise companies according to their needs.

Do you need specific expertise to operate a 5G network?

5G is IT! No in-depth telecommunication knowledge is required to operate a 5G network. Whoever controls his IT, directly himself or indirectly through service providers, is able to operate his own private 5G network.

What does URLLC mean?

With Ultra-Reliable and Low-Latency Communication (uRLLC), highly reliable connections with low latency are established between sender and receiver. The high reliability (Ultra Reliable) and the low latency (Low Latency) are the prerequisites for applications that place high demands on the availability of the signal and the signal transit times, keyword real-time communication. URLLC will be described in the 3GPP standard of Release 16.

What does eMBB mean?

Enhanced Mobile Broadband (eMBB) is a service category according to 3GPP Release 15 that provides an extremely high data rate and supports applications with high data throughput requirements. In this context, 4K, 8K video technology, Virtual Reality (VR) and Augmented Reality (AR) are to be seen as priorities.

What does mMTC mean?

Massive Machine-Type Communication (mMTC) involves services that require a high connection density. This can be as high as one million MTC components per square kilometre. In industry, this typically includes the management of IoT devices (e.g. sensors). In addition, this category of services will also see a dramatic improvement in energy management according to 3GPP Release 17, which can lead to battery lifetimes of up to ten years.

Does 4G (LTE) meet my requirements?

5G is the successor technology to 4G or LTE. Private mobile networks or campus networks can be implemented in both 4G and 5G. Depending on the requirements to be met, it is often sufficient to start with an upgradeable 4G campus network. Should the need for 5G specific parameters develop over the years, upgradeable 4G networks can be partially upgraded to 5G without the need for substitution of all equipment. This makes it possible to use hybrid 4G / 5G networks to operate the digital ecosystem cost-efficiently and with high performance. It depends very much on the individual requirements of the respective company which technology makes the most sense. 4G has the advantage that considerably more devices and solutions are available on the market at more favourable conditions than 5G (status 2020 / 2021).

How can I identify suppliers for the necessary mobile phone components?

There are a large number of established and new suppliers for all components of a mobile network on the market. According to your specifications or driven by the specific requirements, the suitable suppliers can be selected. In this case it makes sense to work with consultants who have access to these suppliers.

Which manufacturers offer 5G technology?

There are a large number of established and new suppliers for all components of a 5G network on the market. According to your specifications or driven by the specific requirements the suitable suppliers can be selected. In this case it makes sense to cooperate with consultants who have access to these suppliers.

Who operates my private campus network?

5G is IT! No in-depth telecommunications knowledge is required to operate a 5G network. Whoever controls his IT, directly himself or indirectly through service providers, is able to operate his own private 5G network.

Is 5G harmful to health?

On the basis of science and technology, laws, ordinances and regulations apply in the respective countries. In Germany, for example, the following applies: "The personal protection limits to be applied to radio installations are laid down in the 26th Ordinance to the Federal Immission Control Act (26th BImSchV). These limit values are in line with the international limit value recommendations of ICNIRP and thus also with the recommendation of the EU Council of 12 July 1999 on the limitation of exposure of the general public to electromagnetic fields (0 Hz - 300 GHz) (1999/519/EC).

What is the right operator model for my campus network?

A well-founded consultation deals primarily and at an early stage with the issue of the operator model. In principle, four models have been identified. From the "as-a-service" TurnKey solution where the entire chain including the operation of the mobile network is placed in the hands of a service provider to the "in-house solution" where the company takes care of all matters itself. In between, there are variations. It depends on which goals and business models your company pursues and which digitisation strategy is pursued.
