Field workers are demonstrating how paper cups can be used for information networking. How does data transmission work? Is paper still useful? For people who are used to storing and sharing data through smartphones, tablets, computers, or USB drives, it might be hard to imagine that paper could also be part of a network. However, at this year’s MWC, some internet applications have surprised attendees, showcasing the potential of future technology. In Ericsson’s exhibition area, a "paper networking" demo caught the attention of many visitors. What exactly is this new innovation? Let’s take a closer look. Print becomes the "User" During the demo, a reporter held a “body connectivity†sensing device connected to a tablet, while the other hand was holding a paper cup. The contents of the cup appeared instantly on the screen. By tapping the screen, more details like calorie count, transportation methods, and distances were displayed. The current “body connectivity†device is quite bulky and not very user-friendly. “These are just concept products; in the future, they will be seamlessly integrated with smartphones,†said an Ericsson representative. According to them, any printed material—whether it’s a paper cup or plain paper—can act as a user once it's embedded with electronic components. This allows users to access information such as nutritional facts or health benefits after recognition. Mats Norin, Vice President at Ericsson, told reporters that besides paper, smartphones, tablets, smart cars, and even trash cans can all become part of the Internet. “Everything around us can have information functions and connect to the network,†he said. “The future is about making every object smart.†Paper networking has various applications, especially in media and advertising. Imagine touching a product ad in a newspaper with your phone and instantly getting full product details, or even purchasing it directly. A delivery company could then bring the item right to your doorstep. Similarly, touching an outdoor movie poster could allow you to watch a trailer or learn more about an upcoming film. Expected to Go Commercial in 3–5 Years The concept behind paper networking isn’t complicated. Using printed electronics, the paper itself contains identification data. When touched, it sends that information to a smartphone or tablet, where it can be converted into videos, text, or other multimedia formats. Currently, printed electronics can produce antennas, sensors, batteries, solar modules, and simple displays. However, the data transfer speed is still limited compared to traditional communication methods. Ericsson’s version includes printed antennas, chips, and batteries to enhance functionality. After nearly a decade of quiet development, the global printed electronics industry is expected to see rapid growth in the next 3 to 5 years. Ericsson’s demo showcased capacitive coupling technology and touch-based data transfer at speeds up to 10 Mbps. Through capacitive coupling, the human body can act as a data cable, allowing data to be transmitted or received by a mobile device.
