Messe Hannover: Telekom builds 5G for the largest exhibition center in the world


The Hanover exhibition center is to be fully equipped with 5G and a hybrid approach consisting of a private campus network with its own frequencies and a public mobile network for visitors. The Lower Saxony Ministry of Digitization is supporting the 5G expansion with over 2.8 million euros.

The former home of Expo 2000 and CeBIT, which was discontinued in 2018 is to receive a 5G network covering the entire exhibition grounds including all halls and parking spaces with a hybrid structure of public and private areas this year. Deutsche Telekom and Deutsche Messe AG announced this on 16th Feb. The project aims to provide 5G coverage totaling more than 1.4 million square meters.

In the first step, Deutsche Telekom wants to equip five halls and the entire outdoor area including adjacent parking spaces with 5G. To this end, 14 5G antennas for the outdoor area and 70 indoor antennas for the first five halls will be put into operation. In the further course of the project, all 30 halls and buildings on the exhibition grounds are to be supplied with 5G. With a covered area of ​​around 500,000 m², it is the largest exhibition center in the world. One of the biggest events after CeBIT is gone is the Hannover-Messe industrial fair.

The public part of the 5G network uses the area acquired by Deutsche Telekom as part of the 5G frequency auction at 3.6 GHz, in which 90 MHz bandwidth is available for up to 1 Gbit / s in the downlink. Slower 5G over the former 3G band at 2,100 MHz and with DSS is not planned for the exhibition grounds. In addition, there will be a private frequency range as a so-called campus network, for which Deutsche Messe has acquired and allocated 100 MHz bandwidth in the 3.7 to 3.8 GHz range from the Federal Network Agency.

The frequency range between 3.7 and 3.8 GHz was left out of the 5G auction. This is available to companies, municipalities or institutions such as universities. The 5G fees for local applications have been fixed since autumn 2019.

With this hybrid approach, visitors are to be supplied with the public 5G network on the entire site, while the trade fair and exhibitors can use the campus network for their applications. The latter area also includes an independent project from Siemens that provides for a 5G campus network in one of the exhibition halls with a focus on use in industry. This network can be used by exhibitors during ongoing trade fairs and by companies for tests and field trials outside of trade fair times.
