The Internet of Things (IoT) – and what it will enable – has been a discussion point for well over a decade, but the speed, low latency and reliability of 5G promise to bring the concept to life. Network slicing will allow a wide range of product types, with distinct reliability and throughput requirements, to be run out of the same architecture, and edge computing will allow nodes to communicate directly with one another, bypassing the network’s core and enhancing speed and reliability. These characteristics underpin some the most interesting projects currently making use of 5G, and have made a plethora of 5G use cases possible. Here are ten of the best.
1. Untethered industrial robots
Robots are already widely used in factories, particularly in the automotive industry. However, 5G’s speed and low latency will ‘untether’ them, meaning they are physically free. Ericsson is currently collaborating with robot manufacturer Comau to develop fully automated untethered robots for use in an industrial setting. These robots will move in response to input from sensors rather than direct human control. Ultimately, they will make use of artificial intelligence and be multipurpose and intelligent enough to adapt, communicate and interact with each other. They will also be able to ‘personalise’ products, leading to more flexible production lines. The robots will work from a 3D image of a customised product (called a digital shadow), allowing them to optimise the manufacturing process by detecting quality issues and making continuous improvements.
2. Robots on farms
Untethered robots will be able to wander through fields determining, via interaction with sensors, which crops need more fertilizer or water, or which are suffering from disease. They might also be able to sift through images of fruit or vegetables using image processing software to determine whether produce is saleable or damaged. A company called FFRobotics has developed a ‘fresh fruit harvester’ that does exactly this. The company’s website states that these robots pick fruit ten times faster than a human harvester.
3. Robots in surgery
Untethered robots would help medical staff lift patients, or move beds and other equipment around the hospital, but perhaps more interestingly, they will also help with surgery. Surgeons located in a hospital will be able to conduct operations remotely. Telecoms company Ericsson is currently working with King’s College, London to develop haptic gloves enabling surgeons to do this. These gloves will be connected to a robotic intermediary located with the patient (perhaps inside a drone). The surgeon would view the operation via a virtual reality (VR) headset, as well as feel pressure transmitted from the robot to the gloves using vibrating motors. The technology relies on ‘edge computing’ systems (computation handled and stored locally) within the surgical device and the robot at either end of the 5G stream.
4. Virtual patient operations (telesurgery)
VR is one of several technologies that lends itself to medicine in interesting ways. Earlier this year, virtual reality software specialist, EchoPixel, launched a 3D viewer for use in diagnostics and surgical planning. This software converts 2D medical imaging data such as MRI and CT scans into VR images that float above an ordinary desktop. Doctors will be able to manipulate and dissect body parts from within the image. In time, haptic technology is likely to be used to make the different parts of the clone – skin, bone and tendon - feel differently to the surgeon, thereby guiding him in his work.
5. VR and palliative care
The low latency afforded by 5G provides far more potential for artificial and virtual reality applications than any previous iteration of the mobile network. AT&T and Vitas Healthcare are working together to combine on a VR product that aims to reduce anxiety and pain for the chronically ill. Patients will wear headsets and interact with scenes that aim to improve their mental health, this might include a walk through their home town or a visit to Machu Picchu in Peru.
6. AI in diagnosis
Artificial Intelligence (AI) is already being used for diagnosis of ailments. For example, in 2017 Stanford computer scientists used a computer vision tool to successfully diagnose early instances of skin cancer. The computers are provided with many thousands of images as well as mathematical functions and algorithms allowing them to extract meaningful patterns. 5G will increase take up of this technology, since it allows for real time rapid learning and calculations when assessing a patient’s symptoms. The government’s ‘industrial strategy’, has seen it open five new AI research centres in the UK (Leeds, Oxford, Coventry, Glasgow and London) focused on image analysis.
7. Self-driving vehicles
Ultimately, self-driving cars are another form of robot, and more than 40 manufacturers are working on robocars. Google’s is particularly interesting. It features a rotating roof top camera containing an array of 64 laser beams with a 200m range, these create images of hazards and other cars. A camera on the windscreen helps it see nearer-range obstacles such as pedestrians. Radars on the front and rear bumpers mean it is able to see cars in front and behind, and it will maintain a distance of 2-4 seconds at all times. An aerial at the rear receives information about the location of the car from GPS satellites. Mapping technology analysing road services, markers, signs and more, is recorded using an ordinary car and fed into the self-driving vehicle’s software. It also recognises signals and gestures, such as those used by cyclists for example. It will interpret these and slow down accordingly.
5G drones are already ubiquitous, but they will come into their own once they are 5G enabled. Although the regulation around air traffic safety is still to be agreed upon, sophisticated autonomous drones, designed for industrial, government and enterprise use, are already in production by manufacturers such as Percepto. These in-the-box-solutions can be programmed to carry out remote surgery, precision agriculture, defence activities, disaster recovery (following forest fires or other natural disasters), and inspection of difficult to reach infrastructure such as oil rigs, electrical systems or derelict buildings. They are likely to be rented ‘as a service’ by different sectors.
9. AR smart glasses and safety
Augmented reality (AR) smart glasses will overlay the real world with useful information. Developers in this field argue that they make the entire world a desktop. There are many interesting examples of glasses of this sort, particularly those for use in an industrial setting. The ODG R-7 are AR smart glasses fitted with stereoscopic displays of 720p each, these are untethered and come with a variety of sensors. Off-site experts in an industrial setting will be able to see what an on-site person is seeing and AI can be used to retrieve step by step instructions around how to fix faults. One can easily see how this might be used by trainee mechanics or someone with a broken boiler in contact with a remote engineer. Miners or people working in dangerous environments might be warned of potential gas leaks by sensors communicating with their glasses. In a standard business context, these glasses will provide useful face recognition and travel guidance.
10. 5G on the underground
The Department for Media Culture and Sport is currently collaborating with various Korean institutions on a project called 5G RailNext to develop 5G infotainment services for public transport. The project will initially test the live deployment of infotainment mobile services using AR and mixed-reality content. The beta test will take place in a subway environment in Seoul and deliver travel information, video streaming and gaming through wearable devices such as headsets.
11. Robots fighting Covid-19
In recent weeks China has managed to ‘flatten the curve’ of its coronavirus outbreaks, reporting only a handful of new cases each day, and 5G technology is playing an integral part in the country’s battle against Covid-19.
One use of 5G tech, which has drawn particular attention is patrol robots, which are being used in busy areas such as airports to monitor citizens, and ensure that people are wearing face masks in public spaces.
The robots were developed by Guangzhou Gosuncn Robot Company, with additional support from IoT hardware and software specialist Advantech. And the robots have already been deployed in airports and shopping malls in cities such as Guangzhou, Shanghai, Xi’an and Guiyang.
12. 5G drone taxis
Getting to and from the airport to the city is time-consuming. So why not fly? A new generation of eco-friendly electric vertical takeoff and landing (eVTOL) aircraft – effectively ‘drones’ you can sit in – are now in advanced prototype stage. Developed by the likes of Airbus, Ehang, Volocopter, Kitty Hawk, Uber Elevate, Terrafugia and PAL-V, they’re pilot-less, autonomous, and have a range of about 50 miles. Potentially perfect for transferring quickly from airport to city, or from airport to airport – such as between Heathrow and Gatwick in London, or JFK and Newark in New York – these so-called ‘drone taxis’ require 5G-powered autonomous airspace identification, crash-avoidance and geofencing so they can’t enter sensitive areas. Expect 5G-enabled air taxis to go mainstream by 2030.
13. Attend the Oscars
Visitors to Times Square had the opportunity to “walk the red carpet” at the Oscars earlier this year, using a 5G-enabled smartphone. Verizon created this world-first Oscars experience using the power of its Ultra-Wideband 5G network, which projected the red carpet experience to fans 2,500 miles away, in New York City.
The Verizon 5G portal transported fans from Times Square to the famous Dolby Theatre in Hollywood, where they were then able to see all of the live celebrity action unfold right before their eyes, as if they were standing on the red carpet themselves.
This was done by placing a Verizon 4K 360-degree camera on the Red Carpet. Using a 5G smartphone connected to Verizon’s 5G Ultra-Wideband network, which operates on a higher mmWave frequency with a wider spectrum bandwidth, fans stepped into a virtual portal that transported them to the real-time Red Carpet.
Once “on” the red carpet, viewers could control what they looked at thanks to a 360-degree camera. They could see the celebrities walk right past them in real-time, providing an innovative, new way to watch the Oscars.
14. Enhancing fashion with 5G
At the 2020 Bafta Awards MTV and Channel 4 presenter Maya Jama made a futuristic fashion statement, by wearing the world’s first 5G-powered augmented reality (AR) dress
The dress itself – a fashion first for 5G use cases – took British designer Richard Malone 250 hours to complete, and the final piece uses an array of technology to collect movement and positional data, which is then fed into an augmented reality app.
The 5G-enabled dress was able to digitally transform itself when viewed through an augmented reality app on a tablet device. And Richard Malone, designer of the 5G-powered AR dress, is already well-known for his unique pieces, which are renowned for pushing the boundaries of what can be achieved with fabric, and with this dress he went one step further.
The dress contained more than 12 full body-length wires and 18 sensor bulbs. To keep all of the technology hidden, it was hand sewn with more than 100,00 stitches. The sensors were tracked using the EE 5G network, allowing Jama and others to interact with the design using a smartphone.
