The development of Internet of things devices is one of the most exciting trends in recent years. However, with so many new wireless devices entering the network, people have expressed great concern about how to manage them effectively. Thanks to 5g and edge computing technology, enterprises will soon transform their networks to release the real potential of Internet of things devices and expand their coverage to previously underserved areas.
What is 5g?
As the latest generation of cellular technology, 5g provides more than just speed improvement (although it can do that). 5g technology is different from the previous technology in that it can transmit data using medium and high frequency signals through radio waves. The existing cellular technology only operates in the low frequency band, can send signals in a wide area, can spread over a long distance and overcome obstacles such as buildings. Unfortunately, low-frequency transmission takes up a lot of bandwidth, which means that radio waves will soon become crowded.
High frequency signals occupy less bandwidth and can transmit more data at the same time. Unfortunately, they lack the coverage of low-frequency signals, which means that they are difficult to penetrate buildings and cannot travel over long distances. The innovation of 5g technology is that it can transmit signals across multiple frequency bands. Cellular mobile signals can be transmitted on lower frequency bands to cover long distances, and then relayed through higher frequency bands to transmit more data and send it to end users faster. By opening the medium and high frequency spectrum, more wireless devices and services can be added without affecting performance or blocking radio waves.
What is edge computing?
The traditional cloud network forms a centralized system for collecting and processing data. The data is collected by the networking device at the network edge and transmitted back to the central cloud server. Then, the server’s computing resources process the data, classify and store it for future use. In some cases, the server sends instructions to devices at the edge of the network. The problem with this arrangement is that it introduces significant delays when data is transmitted back and forth.
Edge computing subverts the traditional architecture and transfers key processing functions from the center of the network to the edge of users. By combining edge data centers with IOT devices that can process data on their own, edge computing can greatly improve network performance and significantly reduce latency. Although the main advantage comes from repositioning processing functions closer to actual needs, the network will also benefit from the perspective of bandwidth because it reduces the total data traffic to and from the center of the network. Because devices can still process data locally or through nearby edge data centers, edge computing networks are more resilient because of their flexibility to collect and process data at multiple locations in the event of a failure in any part of the network.
How does 5g and edge computing work together?
In many ways, 5g and edge computing seem to be designed to complement each other. Although 5g technology can still transmit data over a long distance like the existing cellular technology, its ability to transmit a large amount of data locally makes it a perfect match for the edge computing network. (from IOT home network) in order to make IOT devices more effective, they need a high-level connection at the edge of the network. Although they can store and process data locally, their ability to communicate quickly with other devices in the region makes them truly revolutionary.
In order to maximize the potential of IOT devices, they need sufficient connectivity to quickly transmit and process large amounts of data. For example, an automatic driving vehicle needs not only to acquire data from its own sensors, but also to share data with other vehicles on the road. Edge computing architecture can keep data closely connected, but 5g technology will be necessary to help it reach the required location as soon as possible.
As 5g infrastructure becomes more and more common, edge data centers and IOT devices will be able to form localized processing areas to generate, collect and analyze data locally with minimal delay. In this way, the network edge will no longer be the edge in the traditional sense, but a closed loop composed of interconnected 5g networks, which will make it easier to manage data and determine which data needs to be transmitted back to the centralized server.
Promote digital transformation with 5g and edge computing architecture
5g technology and the one-stop service of edge computing framework will help companies fundamentally change the way they design and deliver network services. Shift the focus to the customer’s edge, rather than designing their infrastructure from the inside out. Smaller, more versatile edge data centers will be a key factor for organizations that want to create dynamic networks that respond to their needs to enhance their IOT strategy.
With the continuous improvement of the processing capacity of Internet of things devices and the increasing demand of customers for data intensive services such as augmented / virtual reality and high fidelity digital media, enterprises will need to find ways to take advantage of the speed and bandwidth potential of 5g connection to provide these services. By combining with edge computing, these services can overcome the delay problems associated with the existing network infrastructure.
