In the business world, we expect one plus one to be greater than two for the simple reason that the whole will be greater than the sum of the parts. In the case of 5G and Edge computing, the outcome is exponential rather than being additive. These two technologies promise to deliver plenty, and hence a combination of the two is expected to yield tremendous results. As per Gartner, the 5G network infrastructure market would be at $8.1 billion in 2020 and IDC forecasts that the 5G connections worldwide will grow with a CAGR of 217% from now till 2023. In the same period, it is also expected that 60% of the infrastructure deployed will be in edge. These statistics are clear forward indications of the complimenting effect of 5G and Edge computing. The article examines, through 3 different angles, how this complementing effect will be playing out in the future. Edge as an enabler for 5G 5G, or the 5th generation wireless technology, can provide ten times higher speed and one-tenth of latency than its predecessor. 5G Core is a fully distributed cloud-native architecture (CUPS & Service Bus Architecture) and deployed on distributed environments.
The infrastructure on which the 5G functional software is deployed has a significant role to play in achieving high performance. Edge computing, on the other hand, through its acceleration components (NPU, GPU, ARM processor arrays and sometimes custom ASICs) and distributed deployment model, allows workloads to be hosted near the user and thereby facilitates high performance and low latency. Edge computing avoids vast volumes of data to be sent to the central cloud for processing, thereby reducing the backhaul traffic load. It is logical to think that Edge computing provides the best hosting method for 5G workloads. The distributed cloud-native nature of 5G allows it to be deployed by keeping only the right functions to lie near the user and others to be located elsewhere. In this way, Edge computing enables the performance of 5G. Fortunately, that both of these technologies are maturing together. Edge as the use case for computer engineer vs computer science The high speed, high bandwidth and low latency provided by 5G make it an exciting connectivity mechanism for those enterprises who work with a large volume of data and require quick feedback. Manufacturing is a good example of where 5G usage can value-add. Digital manufacturing and smart factory floors can use private 5G as a connectivity mechanism and Edge as the infrastructure for processing the data.
