Campus networks on LTE or 5G basis
Business Pain Points

Cellular network: the facilitator of demanding radio links

LTE and 5G provide efficient radio links for private company networks as well.

  • High demands on radio links due to Industry 4.0
  • LTE convinces as IoT network with high performance
  • Smooth development to 5G
  • Quality of service in privately used cellular networks
  • Perfect supplement to WLAN

Business Development 5G

Companies link machines and devices quickly, reliably and securely via LTE or 5G

The Internet of Things (IoT) helps companies to gain access to new fields of business. This was confirmed by 60 percent of companies worldwide, according to a survey of the research institute Forbes Insight. In the vanguard is the industrial sector. To facilitate this, the network connection between the networked "things" and the backend server must correspond to the requirements of the use case – and these can vary. For example, Data for remotely controlled machines has to be transmitted extremely fast and reliably. A smart factory in addition needs a network that simultaneously supports a high number of terminals. And all of these requirements are also increasingly becoming mobile. As a result, radio connections instead of classic cables become more important. The current cellular network standard LTE Advanced (4G) meets these manifold demands: with data rates of up to 1 gigabit per second, latencies of about 20 ms and connectivity for up to 10,000 devices per square kilometer.

The development from 4G to 5G

The performance of the cellular network will increase further, since the standardization organization 3GPP is constantly publishing new cellular network standards. For example, the first specification for 5G New Radio, the cellular network protocol of the next generation, was published in December 2017. However, the term 5G also refers to new technologies for the core network. For example, the current LTE network is being transformed step-by-step into the 5G network of the future. IoT devices will also benefit from this: According to the Ericsson Mobility Report, 88 percent of the wide area connections in the Internet of Things are based on cellular networks.

Quality of service also on the radio link

The majority of networked "things" communicate in close proximity though. In almost half the cases, IoT developers decide in favor of WLAN as radio technology, according to a survey of the software development platform Eclipse. However, this could soon change, above all in the business sector. Thanks to higher transmission quality, cellular networks are also conquering corporate LANs and supplementing existing Ethernet LANs and enterprise WLANs. What is special about this: if a privately used cellular campus network is involved, radio links of a defined quality (QoS) can be realized. This is critical for the success of many applications – and usually not possible with WLAN.
Companies can book an LTE or 5G campus network as managed service and in this way benefit from the know-how and scale effects of an experienced partner. They achieve particularly low latencies – required, for example, for controlling self-driving transport systems – when they combine a cellular campus network with a local edge cloud. This processes all of the data directly on the campus and the data remains local.
Apart from the use of the private radio network, in specific countries it is also possible to transmit the signal of the public cellular network via the campus radio infrastructure. This "dual slice" approach provides much better supply with the public network, also inside buildings.
