Alibaba recently announced that its self-developed NFC technology breaks through the limits of the communications industry, expanding the traditional near-field communication perception distance in any direction from 20 cm to 3 meters, the longest in the world.
Most mobile phone NFC applications have a very short contactless communication distance.
On the one hand, this is due to its operating frequency of 13.56MHz and a communication distance of 0-20cm (in reality, most products are within 10cm).
On the other hand, the shorter distance also makes NFC technology more secure and more suitable for some financial applications. However, the application scope of NFC technology is limited and the expansion of the scene becomes an obstacle.
Dr. Liu Hongqiang, head of Alibaba Cloud's network research team, introduced that the NFC technology has broken through the key bottlenecks in achieving automated logistics, and can be widely used in scenarios requiring long-distance, large-scale, full-category identification of goods information in the future.
For example, in traditional logistics centers, goods in and out of the warehouse are usually manually picked up by workers, take the parcel under the machine scanning completed, workers need to repeat this complex action every day for a long time.
With the application of the latest NFC technology, the machine can be separated by a distance of 3 meters at the same time to complete hundreds of parcels of high-accuracy sensor scanning.
This achievement was accepted by SIGCOMM 2020, the global summit of network communication. Five Alibaba papers were selected, ranking first among all participating Chinese organizations and setting a new Chinese record.
