Juniper Research forecasts that active 5G connections will reach 240 million by 2025, with associated revenues surpassing $65 billion (£42.3 billion) in that year. This implies a compound annual growth rate (CAGR) of 266% between 2020 and 2025, reflecting rapid commercial uptake as networks expand and services mature.
5G is expected to command a premium over current average revenue per user (ARPU) because of its advanced capabilities and new service opportunities, similar to the value uplift observed when 4G was introduced. However, Juniper cautions that even with this strong growth, 240 million connections will represent only about 3% of global mobile connections by 2025, underscoring that full-scale penetration will take longer.
The International Telecommunication Union (ITU) has targeted initial commercialisation of 5G technologies around 2020 and set out comprehensive technical performance requirements for radio systems to support next-generation services. These requirements are being developed to address a broad range of future scenarios and use cases, and the ITU will define evaluation criteria to assess candidate radio interface technologies before wider deployment.
Technically, 5G aims to deliver peak network speeds of at least 10 Gbps and is expected to operate primarily in frequency bands ranging from roughly 6 GHz up to 100 GHz. Key performance goals include much higher spectral efficiency, significantly reduced latency, and a large increase in system capacity. Work is also under way to improve propagation characteristics and minimise penetration losses at higher frequencies so the technology performs reliably in diverse environments. While initial commercial launches began around 2020, the ITU and industry stakeholders anticipate broad consumer and enterprise adoption occurring closer to 2025.
A major impact of 5G will be enabling massive numbers of simple, low-power devices to connect to networks, accelerating the emergence of the “Internet of Everything” (IoE). In smart homes, cities, transportation systems and critical infrastructure, sensors and connected components will proliferate—appliances, vehicles and public systems will exchange data more continuously and intelligently. Juniper Research notes that deploying these wide-ranging services will likely require access to new spectrum bands to meet capacity and coverage needs, and operators and regulators will need to coordinate spectrum availability to support the IoE vision.
