The future is 5G
Explore the technology transforming how we work, play and learn.
5G is the fifth generation of cellular technology. It is a generational leap in technology where everything is new: new spectrum frequencies, new radio and new core network. While 4G’s speed and capacity have accelerated the app economy and mobile video, 5G is a platform for entirely new innovations.
Accenture research shows that companies that invest in advanced network capabilities such as 5G will grow revenue 2.5 times faster in the next three years.
5G and cloud
Previous network technologies were not built for today’s highly distributed world of cloud, edge devices and remote work. Cloud-enabled networks powered by 5G—along with other technologies such as edge, open radio access network (O-RAN), and software-defined wide area network/secure access service edge (SD-WAN/SASE)—seamlessly connect across the dynamic capabilities of the Cloud Continuum, from the public through the edge, and everything in between. As more and more companies are migrating to the cloud, we are only starting to see the business impact of 5G.
5G impact on industries
5G technology is already having a transformative impact on the economy, spurring economic growth by:
Here’s a snapshot of the impact on communications service providers (CSPs) and industries:
Investing in 5G and transforming enterprise networks is a must for companies seeking to unlock the full potential of the Cloud Continuum.
Communications service providers
CSPs will become the provider of 5G networks, devices and services, and a crucial partner across industries. Greater bandwidth, lower latency and the proliferation of post-smart phone era devices will enable enhanced services and higher revenues, as well as open the doors for telcos to expand their products and service offerings beyond pure connectivity.
5G will offer higher flexibility, visibility and security for configurable factories, mobile robots, time-sensitive networks and lower maintenance costs.
5G will provide improved safety of transportation, especially with automated vehicles. It will also offer higher bandwidth and edge computing power for vehicle-to-infrastructure (V2I), vehicle-to-network (V2N) services and machine-to-machine (M2M) feedback loops.
5G will provide reinvented shopping and brand experiences using technologies like virtual reality (VR) in the metaverse.
5G will offer rapid processing of high-quality and high-quantity medical data and richer mobile and home care, as well as greater reliability and lower latency in critical patient applications.
5G will provide enhanced worker productivity and safety and improved asset management through real-time data monitoring and risk mitigation. It will also provide a new foundation for grid modernization and grid resiliency, optimized operational costs and the ability to monetize assets.
5G will offer more interactive and connected classrooms through augmented reality (AR)-driven learning, as well as greater access to resources to enable stronger interactions and democratize education.
It all began with 1G, which was the network that unlocked mobile voice. Then came 2G, which added the ability to send text messages. 3G expanded on that with a network that could handle mobile voice, text and data. Eventually, 4G added mobile internet to the mix, connecting humans with devices.
With 5G, things get even more exciting because 5G will connect everything—humans, machines, objects and devices. 5G will converge the physical world with the digital while adding hyper-personalization for particular use cases. For example, 5G can be deployed as a private network or a network slice, both of which can further customize and enable the Cloud Continuum.
5G’s economic importance could be as revolutionary as electricity or the automobile, and it will play a massive role in transforming economies.
5G is fueling a massive digital shift, from product development to transportation, from entertainment to agriculture.
There are five areas that underpin 5G’s transformative power:
Enhanced mobile broadband (eMBB)
5G delivers high bandwidth and speeds of up to 10 gigabytes per second to enable ultra-high-definition video and data volumes. High-speed mobile broadband enables applications that require rich data transfer in both upstream and downstream directions, like virtual reality and extended reality (XR).
Massive Internet of Things (mIoT)
5G can provide simultaneous connectivity of up to 1 million connections per square kilometer. This dense connectivity is key to implementing advanced massive IoT applications.
Mission-critical services (MCS)
Mission-critical applications like remote intensive care units demand reliability and speed. 5G can carry network traffic with latencies as low as a millisecond when that time is the difference between life and death.
Private wireless networks offer an on-premise and purpose-built network solution that secures business-critical operations. A private 5G network supports indoor and outdoor operations without the impact of legacy and ad hoc wireless designs. Of the executives in our Accenture study, 84% plan to invest in a new campus network or modernize the existing one, and 67% are planning to set up a 5G campus network.
A network slice is a useful solution for wide area networks. It allows a connectivity provider (e.g. a carrier) to create a fit-for-purpose connectivity solution in which the customer (e.g. a utility company) gets a “slice” of the public network tailored to their goals.
5G technology creates new experiences, delivers cost and productivity benefits, unlocks new products, services and revenue streams, and helps harness the value of the Cloud Continuum. 5G networks also support sustainability thanks to the technological shift from legacy networks, driving significant energy demand reductions and reducing carbon emissions.
5G connectivity unlocks new high-speed, low latency applications where edge + artificial intelligence can be used to perform processes 10x or 100x better than humans.

What does 5G mean for IoT?
5G’s substantially-increased network capacity will ensure reliable connectivity for the surging number of simultaneously-connected devices and their diverse usage patterns. 5G can provide simultaneous connectivity to potentially one million connections per square kilometer. This massively dense connectivity is essential to the effective implementation of advanced IoT applications. One example of this is enabling large networks of sensors and machines to capture the rich datasets necessary to apply AI in smart power plants.
How is 5G related to edge computing?
While 5G and edge computing are each powerful technologies, when combined they offer so much more. 5G technology supports the high speed, low latency and device density that are essential for edge computing. With 5G connectivity, edge computing becomes easier to manage, deploy and use. 5G is a catalyst that amplifies edge computing. It makes the edge more mobile, enabling new use cases (e.g. self-driving vehicles, automated retail transactions, smart city projects and more). Together, 5G and edge keep computation and data storage closer to where data is generated, which means better data control, faster insights, continuous operations and increased security. The blend of 5G and edge results in lower operations costs and bandwidth consumption and increased network responsiveness.
What does 5G mean for Wi-Fi?
Wi-Fi is a best-effort technology that is not truly mobile. While Wi-Fi offers low-cost connectivity, ease of use and a large developer community, it can also be less secure than 5G. Compared to Wi-Fi, 5G is more reliable and secure. 5G can also support mobility and is more responsive with ultra-low latency (1ms).
Is 5G secure?
5G comes with security controls such as International Mobile Subscriber Identity (IMSI) encryption and the Security Edge Protection Proxy (SEPP) function. These features create new tools that a cybersecurity team can use to reduce risk and create a more secure network. However, the exponential increase in devices, services and zones would require a fundamental reimagining of security design.
What radio spectrum is 5G using?
Radiofrequency spectrum is the fuel of all wireless communications. Depending on geography, regulators allocate 5G spectrum into two to three broad ranges: high-band spectrum (e.g. millimeter-wave), which supports the fastest 5G speeds; mid-band spectrum or sub-6 gigahertz (e.g. 1-6 gigahertz), which offers a good mix of coverage and capacity; and low-band spectrum (e.g. below 1 gigahertz), which provides strong wide-area and in-building coverage.
