This discrepancy usually leads to inaccurate WTP values, which affect pricing strategies. Our quantitative online survey with German consumers (N = 215) examines the HB of WTP for different mobile phone plans as an example of a widespread consumer good. The aim is to focus on the correlation between hypothetical and actual WTP and the influence of socio-demographic factors on the HB. We used the Certainty Approach to correct hypothetical WTP data to reflect actual payment behavior. The findings show that hypothetical WTP values are generally higher than current expenditure, which demonstrates that HB significantly affects WTP measurements in the context of mobile communications products. The applied Certainty Approach successfully reduced this discrepancy. We found a moderate negative correlation between actual WTP and the extent of the HB, indicating that higher actual WTP is associated with lower bias. Moreover, socio-demographic factors such as age and income do not significantly influence the HB. This study suggests pricing strategies should consider HB-adjusted WTP values to avoid management decisions based on inflated hypothetical data.

However, assessing consumer trust is challenging, as contractual obligations or high switching costs can lead to misinterpretations. This study investigates consumer trust in mobile providers in Germany. Initially, we conducted 13 qualitative online interviews with industry experts in Germany (except one from Switzerland) to develop hypotheses, which we then tested through a quantitative online survey of German consumers (N = 502). Contrary to the experts’ critical assumptions, the findings showed that consumer trust exceeded expectations. We found no correlation between the duration of customer relationships and trust. These results are especially relevant for mobile providers. Moreover, marketing/product managers from other sectors with comparable consumer goods (e.g., subscription-based media products or information goods) can also gain insights into strategies to enhance consumer trust and manage customer relationships.

B2C Product and Price Policy of Mobile Providers – Insights from Qualitative Expert Interviews in the German and Swiss Market

We interviewed employees of mobile network operators, service providers, consultancies, a research institute, and a price comparison portal to gain insights into pricing strategies, willingness to pay (WTP), and other aspects of mobile markets (e.g., 5G technology). As a result, the experts in the B2C sector see the main challenges for 5G (and future technologies) in the lack of market-ready use cases, restrictive regulatory framework conditions, and parallel/hybrid technologies. The findings are particularly relevant for mobile providers to set competitive prices and increase profitability. Product managers from other industries and economic or marketing scientists can also benefit from the research results on pricing and WTP, including the hypothetical bias (HB).

Mobile Payment in Deutschland – Anbieter und Geschäftsmodelle

Dieser kann u. a. durch die Akzeptanz von kundenfreundlichen Zahlungsmethoden generiert werden (Breinich-Schilly, 2020). So kommen z. B. Geschäfte, in denen Bargeld als einzige Zahlungsmethode akzeptiert wird, für knapp jeden Fünften nicht mehr in Frage (Unzer, 2021). Mobile Payment (MP) ermöglicht, mit dem Smartphone am Point of Sale (POS) zu zahlen (Schmelter et al., 2022). Dieser Beitrag soll einen kurzen Überblick über die Anbieter(typen) im deutschen MP Markt geben, mit dem Fokus auf Proximity MP im stationären Handel am POS in Deutschland.
5G-Medienproduktion: Technologie, Anwendung und Fallstudie einer 5G-Liveproduktion

Für die Medienbranche bieten 5G-Mobilfunknetze verschiedene Vorteile, die von einer flexibleren Produktion über qualitativ hochwertigere Übertragungsformate und garantierte Bandbreiten bis hin zu niedrigen Latenzzeiten reichen. Medienproduktionen stellen aber häufig besonders hohe Anforderungen an Dienstemerkmale oder Netzkonfiguration, die in der Praxis nicht oder nur eingeschränkt über öffentliche 5G-Standarddienste abzubilden sind. Umfassendere Konfigurationsmöglichkeiten bieten 5G-Campusnetze, bei denen es ich um lokal abgegrenzte 5G-Netzinfrastrukturen für geschlossene bzw. private Nutzergruppen handelt. Diese können als virtuelles 5G-Campusnetz über Netzwerkressourcen bzw. sogenannte „Network Slices“ über öffentlicher 5G-Netzbetreiber bereitgestellt werden. Neben der Nutzung öffentlicher 5G-Netze ist es in Deutschland möglich, über eine Beantragung bei der Bundesnetzagentur ein eigenes, privates 5G-Netz zu installieren. Die Einsatzmöglichkeiten derartiger privatgeführter Netze sind vielseitig und branchenübergreifend. Sie bieten den Betreibern die umfassendste Möglichkeit, die Bereitstellung von 5G-Mobilfunkdiensten auf ihre lokalen Anforderungen am Standort abzustimmen. Im Medienbereich können 5G-Campusnetze insbesondere flexiblere Möglichkeiten für hochwertige Medienproduktionen an Veranstaltungsorten oder Produktionen im Film- und Fernsehbereich bieten. Nachfolgend werden zunächst Medienproduktionen als Anwendungsfeld von 5G-Technologie im Allgemeinen betrachtet. Darauf folgt die Fallstudie einer 5G-Liveproduktion, die im Rahmen des „5G Media & Production Hackathons“ im Mai 2022 von der Hochschule RheinMain in Zusammenarbeit mit der netorium AG in Wiesbaden durchgeführt wurde.
5G-MEDIENPRODUKTION - TECHNOLOGISCHE GRUNDLAGEN, INFRASTRUKTUR UND PRAKTISCHE GESTALTUNG

Ein potentieller Anwendungsbereich ist die Medienproduktion. Durch die Implementierung der 5G-Technologie wird die gesamte Wertschöpfungskette einer Medienproduktion beeinflusst. Dieser Beitrag beschreibt die Realisierung einer 5G-Medienproduktion über das öffentliche Mobilfunknetz anhand einer Fallstudie. Hierbei liegt der Fokus auf der technischen Infrastruktur und deren Umsetzung. Die Ergebnisse des Projektes zeigen, dass das öffentliche Mobilfunknetz noch nicht hinreichend belastbar ist, um eine 5G-Medienproduktion zuverlässig und stabil durchzuführen.
5G as an Innovation Driver for Media Productions: Application Scenarios, Case Studies, and Perspectives

Users have a growing range of entertainment [5G Virtuosa (Virtuosa: Exploring 5G and virtualization in broadcast production. 5G Virtuosa, n.d.)]. Media producers must adapt to consumer needs in this fierce competition by pushing live formats and implementing live audience feedback. This is challenging because the infrastructure is mainly based on 30-year-old SDI technology [5G Virtuosa (Virtuosa: Exploring 5G and virtualization in broadcast production. 5G Virtuosa, n.d.)]. One solution is fifth-generation (5G) mobile communications, which “forms the basis for the development towards a networked society” [Deutsche Messe 5G smart venue (from idea to reality. 5G smart venue, n.d.)]. This paper examines which use cases suit private 5G campus networks, focusing on media productions in the German market. In Germany, companies and institutions can apply for licenses to operate private 5G private networks that are referred to as 5G campus networks (“Campus-Netze”). These networks offer a range of benefits to the media industry, from more flexible production to higher-quality transmission formats, guaranteed bandwidths, and low latency. In the German market, 5G technology deployment around media productions already exists but is not widespread. Only 4% of campus licenses primarily relate to media production [according to Bundesnetzagentur (Übersicht der Zuteilungsinhaber für Frequenzzuteilungen für lokale Frequenznutzungen im Frequenzbereich 3700–3800 MHz/Overview of frequency assignment in the frequency range 3700–3800 MHz. Bundesnetzagentur, 2022, February 16)]. This paper aims to investigate the status quo and potential of 5G media production in Germany in more depth. We present the findings of a case study analysis and interviews with various stakeholders in the German media industry. Finally, we give practical insights on the technical readiness for live streaming from a 5G media production hackathon at the RheinMain University of Applied Sciences.

The results show that more than half already own a 5G smartphone and these customers are less price sensitive. The accepted price range for the monthly 5G surcharge ranges between 10.00 and 15.40 Euros. Two thirds want more transparency in 5G pricing, while price is the most crucial factor (4.2/5.0), followed by data volume (4.1/5.0) and network operator/coverage (4.0/5.0). The results are particularly interesting for providers as the target group for 5G is quite diverse.
