More About Dell'Oro Group
Dell'Oro Group focuses on quantitative market research for telecommunications, networking, and data center infrastructure, serving enterprise buyers, network operators, technology vendors, and financial institutions that require structured market data to support planning and investment decisions. Its research outputs are used by CTO organizations, product management teams, strategy leaders, and equity analysts to benchmark vendor positioning, evaluate addressable markets, and track technology adoption across multiple infrastructure domains.
The firm structures its coverage into technology-specific programs, each tracking market size, vendor share, and forecast metrics across defined product categories. These programs span carrier networks, including mobile radio access and core networks (telecom infrastructure), fixed broadband access (broadband networking), optical transport (optical networking), and service provider routing and switching (IP networking). In the enterprise domain, coverage includes campus and branch networking, wireless Local Area Network (LAN) (enterprise networking), data center switching (data center networking), and related physical and virtual network functions.
Dell'Oro Group’s research incorporates analysis of architectures and technologies commonly deployed in modern infrastructure environments, such as 5G and Long Term Evolution (LTE) (mobile networks), fiber-based access and Passive Optical Network (PON) technologies (broadband access), Ethernet and IP/MPLS (routing and switching), and virtualization approaches including Network Functions Virtualization (NFV) and Software Defined Networking (SDN) (network virtualization). The firm also examines interaction points with cloud architectures, including hyperscale data centers, cloud networking designs, and the role of white-box hardware and disaggregated software in network infrastructure deployments.
Enterprises and service providers use Dell'Oro Group’s reports and datasets to compare infrastructure vendors, evaluate technology roadmaps, and build business cases for network upgrades or new services. Financial institutions use the same data to assess market trajectories, competitive dynamics, and revenue exposure across telecom and networking segments. The firm’s analyst commentary and forecast models offer structured views on topics such as 5G deployment progress, migration from hardware-centric to software-based network functions, and adoption of high-speed Ethernet in data centers.
Within a directory or taxonomy, Dell'Oro Group aligns most directly with categories such as telecom and networking market intelligence (research and advisory), data center infrastructure market analysis (research services), and technology adoption forecasting (analytics). Its offerings do not constitute operational IT products; instead, they provide datasets, written research, and analyst access that support strategic planning, competitive analysis, and capital allocation across telecom, networking, and data center technology domains.
