| Will 5G replace existing network technology? |
| 2021.07.20 |

The lightning speed and ultra-low latency of 5G are expected to replace current technologies such as Wi-Fi and broadband in the next few years, especially in IoT networks. 5G will promote the connectivity revolution. As CNET reported, “it can unleash the full capabilities of other hot technology trends to promote autonomous vehicles, drones, virtual reality, and the Internet of Things.”
The realization of this promise may be slower than many people expected, especially in areas with low population density, which will require substantial investment in infrastructure. 2019 is touted as "the year when 5G becomes a commercially viable technology." However, as providers such as Verizon have successively launched 5G networks in major U.S. cities, their ability to extend millimeter wave coverage to suburban and rural areas has been limited. Potential users of the 5G Internet of Things, such as municipalities, manufacturers, and healthcare providers, will need time to formulate reasonable implementation strategies.
Given the challenges of building adequate infrastructure and maintaining 5G network security, the question of whether or when 5G will completely replace current services is not easy to answer. This is also affected by the fact that most 5G networks in North America use the non-standalone (NSA) 5G version, which depends on the underlying LTE core network. Providers plan to switch to standalone (SA) 5G in the future, but this will take time. Currently, advanced 4G LTE, Wi-Fi and edge processing solution platforms support the rapid expansion of connected mobile and IoT devices. The consulting firm said that these technologies will continue to coexist with emerging 5G networks, and that 5G is not expected to be fully deployed until at least around 2025.
The role of current network standards in the 5G world
As predicted, although 5G may eventually replace current cellular standards in the development of the Internet of Things, other technologies such as Ethernet may continue to coexist with 5G networks. The opinion of most experts is that 5G networks will be a supplement, not a replacement for fixed broadband services.
During the gradual transition to 5G, other businesses will continue to move forward to meet the ever-expanding demand for the Internet of Things. The complementarity of 5G and existing technologies may also extend to Wi-Fi. Wi-Fi in particular remains a powerful wireless solution for various use cases. Despite the revolutionary potential of 5G and the heated discussion about its applications, the Wi-Fi market is expected to grow by 21.2% by 2022. The quality and performance of Wi-Fi will be improved, and 5G may not completely replace Wi-Fi for a period of time.
5G innovation in the Internet of Things
When it comes to many IoT application cases such as smart manufacturing, some companies have already begun to study what 5G can replace or start over. For example, Audi, BMW and Volkswagen have proposed 5G to replace their Wi-Fi and Ethernet networks. 5G will surpass these in some key aspects, making it a better choice for a variety of IoT applications, especially those that require fast mobility and ultra-low latency, such as manufacturing, self-driving cars, and healthcare. Those companies that are willing and able to invest in infrastructure will be ready to reap the transformative benefits of the 5G IoT ecosystem. The transition from NSA 5G to fully independent SA 5G will further release the full power of 5G functions.
Expansion of 5G infrastructure for the large-scale Internet of Things faces many challenges. They go beyond the nuanced standards adoption work done by 3GPP to ensure interoperability, including the development of short- and long-term growth plans, solutions to reduce power consumption, and the expansion of backhaul network and Internet capacity to handle data transmitted over 5G networks. Large amounts of data. Before 5G meets these challenges, we may continue to see the development of LTE, Wi-Fi, Ethernet and other network technologies. The overall transition will take some time. It seems that the deployment of the Internet of Things will develop to all 5G, while also taking advantage of the current advances in wireless and wired network technology.
