Vodafone's Private 5G Network Revolutionises Ford's Manufacturing Processes

Vodafone’s 5G is completely transforming production at Ford’s E:PrimE (Electrified Powertrain in Manufacturing Engineering) facility in Dunton, Essex, UK.

GSMA produced a case study to explain the details. The following is from GSMA's case study

The Ford Motor Company is using a mobile private network to enable an electric vehicle plant in the UK to enhance production quality in real-time. A combination of 4G and 5G connectivity provided by Vodafone UK enables Ford to analyse and control the new laser welding machines used to manufacture batteries and electric motors for vehicles.

Although automotive plants are highly standardised with repetitive processes for assembling parts to tight tolerances, Ford still sees variations that can impact the efficiency of the plant and the quality of finished products. These can be as subtle as changes in temperature, or even sunlight affecting the cameras used to detect issues on the production line. Low latency connectivity is required to enable the factory to react quickly: if conditions change the factory needs to be able to change the settings on the machines within milliseconds to continuously optimise production quality.

The new private mobile network is enabling Ford to capture a continuous flow of data from sensors installed throughout its electric vehicle factory in Essex. As a result, it can monitor the end-to-end production process and make rapid adjustments automatically in response to changes in the environment, input materials and other factors. These quick configuration changes are designed to maximise the quality of the finished products

The reliable, high-speed wireless connectivity provided by 5G enables Ford to capture the vast amounts of data generated by its new laser welding machines. As manufacturing the motor and battery of an electric vehicle requires around 1,000 welds, the welding process can generate up to 500,000 pieces of data per minute.

The welding machines generate very “high amounts of heat to fuse pieces of copper together and therefore make a perfect circuit,” explains Chris White, Ford’s 5GEM project lead. “As we do that, we collect data to make sure that we know your car is perfect and won’t have any issues. That data is incredibly important to us and that’s why 5G is critical going forward.”

Ford also uses the new 5G private network to optimise maintenance, replacing parts before they fail, thereby eliminating unnecessary downtime of the production line. At the same time, the connectivity enables Ford’s equipment suppliers to use augmented reality and virtual reality headsets to provide the automaker with remote support and/or test new configurations. 

To help it harness the expertise of partners and suppliers, Ford uses the 5G connectivity to create ‘digital twins’ of its processes that experts can use to develop optimal welding solutions, without stopping the factory. 

For example, the 5G network is enabling collaborative working with experts at The Welding Institute (TWI) based in Cambridge. Via 5G, these experts can help Ford’s on-site engineers master the new welding technology. To do that, TWI needs access to “many gigabytes of information,” notes Chris Allen, Senior Laser Welding Engineer, TWI. “5G enables those kinds of large volumes of data to be moved around with greater ease.”

The connectivity solution provided by Vodafone, which uses its mid-range 1GHz – 6GHz spectrum, gives Ford control over provisioning and administration processes, such as activating/deactivating SIM cards. 

“Connecting today’s shop floor requires significant time and investment,” concludes Chris White of Ford. “Present technology can be the limiting factor in reconfiguring and deploying next-gen manufacturing systems. 5G presents the opportunity to transform the speed of launch and flexibility of present manufacturing facilities, moving us towards tomorrow’s plants connected to remote expert support and artificial intelligence.”

IEEE 802.11be Extremely High Throughput (EHT), a.k.a. Wi-Fi 7

We have been writing about Wi-Fi for a long time, weather it's to do with indoor connectivity , competition with 5G or just a name change to something simpler. When we last wrote about WiFi 6, a.k.a. 802.11ax, we were expecting a quick adoption of the technology in the industry. We are still not there yet.  You know what's strange? None of the new @madebygoogle gadgets from yesterday support Wi-Fi 6. Not the Pixel 5, not the Pixel 4a 5G, not the Nest Audio, and not the new Chromecast. pic.twitter.com/QtJ8iB9FeO — Ry Crist (@rycrist) October 1, 2020 Take for instance the new iPhone 12 supports Wi-Fi 6 in all their models as one would expect but none of the new Google Pixel phones (4a, 4a 5G and 5) support it. In fact none of the new Google devices support it. Which is rather bizarre. While we are still looking forward to Wi-Fi 6 becoming widespread, IEEE has already started working on the successor of 802.11ax, 802.11be - Standard for Information technology--Telecommunicati

CSI-RS vs SRS Beamforming

In an issue of Signals Flash by Signals Research Group (SRG), they talked about 2 different types of MIMO. Quoting from their journal, "CSI-RS versus SRS. Those operators that have tested or made token use of MU-MIMO leverage a flavor of MU-MIMO that is based on CSI-RS. The MU-MIMO network we tested was based on SRS, which makes it far more likely to observe sixteen spatial layers (versus eight)." I reached out to Emil Björnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Linköping University to see if he has explained this in any of his videos. Here is what he said: " I'm not talking about 3GPP terminology in any of my videos. But you can listen to the slides that starts around 12:40 in this video (embedded below) . If you are looking for CSI-RS vs SRS based MU-MIMO, then jump to around 12:40 in this video where you can see CSI-RS being referred to as "grid of beams" and SRS is similar to the other option, which is t
