Brazil Tests 5G Tech for IoT-Fueled Blockchain Integration


Blockchain technology is being integrated with the Internet-of-Things (IoT) across sectors of the economy. From the tracking of the supply chain to financial applications, several analysts agree that the blockchain’s capabilities should increasingly be integrated with the inter-connectivity between devices in a new digital economy in which machines will make payments to other machines.

One of the first presentations of a proof-of-concept in this field was made in June between the IOTA Foundation and global automaker Volkswagen during the Cebit 18 Expo. The application, which is dubbed “Update Over the Air,” will allow cars to receive software updates through IOTA’s DLT Tangle protocol safely and quickly.

However, for this digital revolution to really happen, experts have pointed out that telecommunications technology needs to move forward. To connect different objects interacting with each other, many point out that it is necessary to develop faster connection networks such as 5G, which has been tested in the city of São Paulo, Brazil.

Next-Gen Tech

As the organizers of Futurecom revealed, the city of São Paulo is receiving the first tests with the technology. The deadline for evaluations is stipulated to last a week and happens in a neighborhood of high population density. Initially, the signal is pointed to a commercial building to evaluate the performance of vertical coverage in an indoor environment. Then the horizontal coverage will be tested.

This new generation of telephony will operate at frequencies that allow more powerful connections, which multiplies the amount of information that each point sends and receives in every second. The use of standalone vehicles has been pointed out as one of the main advantages of 5G to the public. Companies like Ford, Qualcomm and Panasonic have performed well in their tests of communication between traffic lights, cars and other elements of traffic.

A technology called C-V2X (cell-vehicle-and everything else) that connects chips deployed at semaphores, cars, motorcycles and smartphones through the cellular network was tested in Germany. With the tool, drivers are warned of braking, red signals and a possible presence of people on the track, which allows them to be more prepared for unforeseen events.

During the tests, the chips communicate at a rate of 10 times per second, which ensures virtually instant notification. Expectations are that the connections can be extended to bridges, track works and other elements encompassing the entire transit experience. Tech experts say that it will be possible to know when drivers will change lanes or brakes, even if they are not in the field of vision.
