The final presentation and roadshow for the 2025 World "AI+Radio" Challenge is set to take place on Dec 1 on the 3rd floor of the Shanghai People's City Practice Exhibition Hall, located at No 630 Anpu Road in Yangpu district.

The competition calls for global researchers, technology enterprises, and science enthusiasts to jointly address key technological challenges such as low-altitude drone defense, promoting AI innovation, and international collaboration in spectrum management.

Centered on low-altitude drone scenarios, the contest covers problem design, dataset compilation, and technical challenges. These include topics such as "radio signal recognition for low-altitude drone targets and signal format analysis, representing some of the most cutting-edge applications in the "AI+Radio" field.

In addition to cash prizes, the event collaborates with local industries, leading enterprises, and financial institutions to provide implementation support for winning teams and promising solutions with strong practical application potential and advanced technological value.

Technically, the competition demonstrates diversity and maturity in model development. In the preliminary round, 15 large language model submissions were received. While one used a mainstream Transformer architecture, the other 14 were specialized models tailored for vertical applications in radio technology, showcasing the broad prospects of integrating AI with radio applications.

The final models show even greater professionalism, with participants focused on uncovering the intrinsic characteristics of radio signals while striking a balance between lightweight design and accuracy in their model architectures. Many teams adopted integrated model approaches for target-signal detection and recognition, with most aiming to ensure stable recognition capability in complex scenarios. These efforts not only improved precision but also validated engineering feasibility under constrained computational power, complex noise, and non-stationary backgrounds.

The competition solicited global proposals through online platforms and has attracted participants from over 20 countries, with 276 teams registering and submitting their entries.

After multiple rounds of expert review and solution evaluation, 61 teams advanced to the finals, with 24 university and enterprise teams proceeding to the final presentations and roadshow.

The university group includes 12 teams from institutions such as Tsinghua University, Beijing Institute of Technology, Fudan University, and Shanghai Jiao Tong University. The enterprise group comprises 12 teams from organizations including NetEase and the Institute of Software at the Chinese Academy of Sciences.

During the on-site finals, the teams will compete separately, and judges will award one first prize, two second prizes, and three third prizes in each category at the award ceremony.
