Comment Hanover Fair — Industry occupies 5G

Auf der Hannover Messe 2019 nimmt 5G erstmals breiten Raum ein.
5G is one of the hottest topics during Hanover Fair 2019.

The fifth generation of mobile phones has been talked about for far too long, but apparently there has been a lack of implementation so far. At this year's Hannover Messe, the 5G topic seems to have moved on. There it means »industry 4.0 needs 5G«.

The industry waits obviously not only longingly for 5G, but would also like to actively co-design the new fifth mobile communications generation. On the Hanover fair (HM) one does not see consumer and smartphone users in foremost place of the users contrary to the earlier mobile communications generations. They could also live with 4G or LTE for a while, they are convinced. Rather, 5G has the potential to meet completely new automation requirements. This high significance for industrial automation is reflected in the 5G arena at HM, where on five days there was nothing but the use of 5G away from smartphone users.

In addition, Deutsche Messe announced that it is probably the first and so far only trade fair company in the world to equip its grounds with a comprehensive 5G infrastructure. The 100-hectare exhibition site will thus gradually develop into an innovative multifunctional campus that will be available 365 days a year as a test field for 5G real-time applications. In addition, a new 5G trade fair is to be launched in autumn 2020: the 5G CMM Expo.

Gartner: IoT communication in first place

Last year, the market research company Gartner investigated the topic of »5G use cases and adaptation«, in which 185 companies were surveyed in a non-representative study. The result of the study was, that the Internet of Things would benefit first and foremost from the introduction of 5G. Two thirds of the surveyed companies want to develop IoT applications based on 5G by 2020. The most important applications are:

Communications with IoT devices (59%)

Video transmissions including AR and VR (53 %)

Remote control and automation

Stationary Wireless Broadband and

Calculation-intensive analyses via edge computing

Sylvain Fabre, author of the Gartner study, was surprised by the importance of IoT communication, as LTE-M and NB-IoT already offer alternatives at lower data rates.

5G -- high throughput, real-time capability, energy-efficient

However, 5G offers a number of features that clearly outperform previous technologies: With up to 20 Gbit/s, the possible data rates can be increased by two orders of magnitude. Latency times of up to 1 ms enable real-time applications via mobile radio for the first time. Thanks to reduced energy consumption, battery life of up to 10 years is possible. In 5G networks, up to one million end devices per square kilometer should also be able to send and receive data. Highest reliability of the transmission channel allows complex industrial applications, which were not possible so far. While a 4G/LTE antenna comprises only four transmitting and receiving units, a 5G antenna comprises sixty-four, which ensures a much more targeted and close-meshed signal supply. This provides for more stable connections that hardly break off and for drastically lower response times in data traffic.

So it's no wonder that the protagonists of Industry 4.0 are part of the closest 5G fan club, while traditional mobile phone users don't complain about 4G/LTE as long as it's available away from areas with limited service. But there is another glowing 5G enthusiast beyond industrial automation: the automotive industry. Because without 5G there will be no autonomous driving.
