The total number of 5G connections is predicted toreach 1.5 billion globally by 2025, rising from only 5 million in 2019, according to Juniper Research. 5G connectivity is a gamechanger with the potential of creating a ubiquitously connected world, further powering the hottest tech trends today such as Internet of Things, Artificial Intelligence, Augmented Reality, and many more. It is all due to its revolutionary specification requirements, namely:
More efficient capabilities mean that users will enjoy also better speed performance than ever before. 5G speed tops out at 10 gigabits per second, that is a hundred times faster than the current 4G technology.
But what is it exactly that makes 5G much faster? According to communication principles, the shorter the frequency, the larger the bandwidth. The use of shorter frequencies for 5G networks, namely millimeter waves between 30GHz and 300GHz, is the reason behind a spectacular 5G speed performance. Moreover, this high band 5G spectrum provides the expected boost not only in speed but also in capacity and low latency.
Beyond speed improvement, 5G technology offers an extremely low latency rate, reducing drastically the delay between the sending and receiving of information from 200 milliseconds for 4G to 1 millisecond with 5G.
For example, it takes on average 250 milliseconds or 1/4 of a second for humans to react to a visual stimulus. With 5G connectivity, a car could react 250 times faster than a human. Imagine it could also respond to a multitude of incoming information and communicate with other vehicles or infrastructure within milliseconds. 5G is expected to create new-generation IoT ecosystems where networks can serve communication needs for billions of connected devices, with the optimised trade-offs between speed, latency and cost.
The main evolution compared with today’s traditional networks is that, beyond data speed improvements, new IoT and critical communication use cases require a new level of performance specifications. Unlike most current IoT services that make performance trade-offs to get the best from traditional wireless technologies, 5G networks are designed to bring the improved performance needed for massive IoT.
5G has greater bandwidth, meaning it can support many more connected devices than previous networks. Compared to 4G, 5G means at least 100 times more connected devices, meaning that 5G is able to handle 1 million devices for 1 square kilometer.
Low latency is what provides real-time interactivity for cloud services, which is crucial for numerous services such as self-driving cars, for example. Furthermore, low power consumption is what could allow some connected objects to function for months or years without the need for human assistance.
5G also allows network slicing tailored to each use case to support all communication needs. This new approach is designed to allow simple virtual network configurations to align network costs with applications needs better.
As often happens to new, previously unknown technologies, there were some erroneous health concerns raised in media about 5G safety. After numerous studies, there is no concrete evidence that radiation from 5G phones poses any more risk than a standard cell phone making it completely safe to use.
Each generation of wireless network brought a brand-new set of opportunities and use cases. The current newcomer, 5G, makes no exception and will be focused on Internet of Things and critical communications applications. The use cases span across the Fixed wireless access, Massive M2M and Ultra low-latency IoT critical communications domains.
Some examples of use cases leveraging low latency are Vehicle-to-Everything (V2X) communication, immersive virtual reality gaming, remote surgical interventions or simultaneous translation.
The 5G technology is tailored to serve multiple needs depending on the context. Some key applications like self-driving cars require extremely low latency rather than fast data rates. Conversely, for enterprise cloud-based services with sophisticated analytics speed improvement is a priority over fast response.
