The research process for this study involved the systematic gathering, recording, and analysis of data on customers and companies operating in the private 5G market. This process involved the extensive use of secondary sources, directories, and databases (Factiva and OANDA) to identify and collect valuable information for the comprehensive, technical, market-oriented, and commercial study of the private 5G market. In-depth interviews were conducted with primary respondents, including experts from core and related industries, as well as preferred manufacturers, to obtain and verify critical qualitative and quantitative information and assess growth prospects. Key players in the private 5G market were identified through secondary research, and their market rankings were determined through a combination of primary and secondary research. This research involved studying the annual reports of top players and conducting interviews with key industry experts, including CEOs, directors, and marketing executives.

Secondary Research

Various sources were utilized in the secondary research process to identify and collect information relevant to this study. These include company annual reports, press releases, investor presentations, white papers, technology journals, certified publications, articles by recognized authors, directories, and databases.

Secondary research was primarily used to gather key information on the industry’s value chain, the total pool of market players, market classification by industry trends at the most detailed level, regional markets, and key developments from both market- and technology-oriented perspectives.

Primary Research

Primary research was also conducted to identify the segmentation types, key players, competitive landscape, and key market dynamics, including drivers, restraints, opportunities, challenges, and industry trends, as well as the key strategies adopted by players operating in the private 5G market. Extensive qualitative and quantitative analyses were conducted across the complete market engineering process to present key information and insights throughout the report.

Extensive primary research has been conducted following the acquisition of knowledge about the private 5G market scenarios through secondary research. Several primary interviews were conducted with experts from the demand side (vertical and region) and the supply side (network type, frequency band, cloud model, offering, spectrum allocation, organization size, and vertical) across four major geographic regions: North America, Europe, Asia Pacific, and RoW. Approximately 60% and 40% of the primary interviews were conducted from the supply and demand sides, respectively. These primary data have been collected through questionnaires, emails, and telephonic interviews.

Notes: The three tiers of companies have been defined based on their total/segmental revenue as of 2025: Tier 1 = > USD 1 billion, Tier 2 = USD 1 billion–USD 500 million, and Tier 3 = < USD 500 million.
Other designations include sales, marketing, and product managers.
