Why is the 2026 World Cup a technological step forward?
The sports industry, especially football, has always had a traditional link with classical rules and structures.
However, the need for more justice in refereeing, the necessity to maintain the physical health of the clubs’ expensive assets (players) and the growing demand of fans for a richer visual experience have changed the football management paradigm. The 2026 World Cup is the turning point of this paradigm shift. Expanding the competition to 48 teams and holding games in a wide geographical area with completely different climates made the traditional management ineffective. For this reason, FIFA has turned the infrastructure of the host stadiums into data processing centers with large investments; Centers that analyze millions of data every second and transfer them to the decision chain.
Semi-automatic offside detection system
Undoubtedly, the most controversial and sensitive decisions in football are related to the offside rule; Where centimeters and milliseconds determine the fate of a country’s championship. After initial tests in the Arab Cup and the initial version in the 2022 World Cup in Qatar, FIFA has unveiled an advanced version of the semi-automatic offside system for the 2026 tournament. This system is a perfectly coordinated network of hardware and software that relies on edge computing.
Ceiling cameras and in-ball sensors
The hardware core of this system includes two main parts. The first part is the installation of 16 dedicated tracking cameras in the roof structure of each stadium. Unlike TV broadcast cameras, these cameras are designed only to extract location and operate at a frequency of 50 frames per second (one frame every 20 milliseconds). The task of these cameras is to continuously monitor 29 separate data points of each player’s body. These points include organs such as toes, knees, shoulders, hands and head, which can be used to score goals according to international football rules. The second part is the smart ball of the tournament. In the geometric center of this ball, there is an inertial measurement sensor that transmits data with a stunning frequency of 500 Hz (500 times per second). This sensor measures the acceleration, speed and direction of the ball and records exactly the microsecond that the foot of the passing player hits the ball. The combination of ball sensor data and 29-point cameras eliminates any human error in recognizing the exact moment of the pass.
The great innovation of 2026
In previous eras, the AI would send its alerts to the video assistant referee (VAR) room, and the video referees would announce the result to the referee after manually reviewing the lines; A process that sometimes takes up to 2 minutes. In the 2026 World Cup, artificial intelligence is equipped with a fast audio processing algorithm. If the margin of error of the offside position is more than 10 cm, the system will automatically send a direct audio signal to the referee’s headset and assistant referee in a fraction of a second. This prevents the continuation of dead games and injuries caused by accidental starts.
Transforming data into intuitive images for fans
One of the challenges of VAR technology in previous years was the lack of transparency for fans inside the stadium and television viewers. Advanced SAOT system has solved this problem through 3D modeling. All the players in the tournament have undergone detailed physical scans before the matches. After the offside is confirmed by the system, the artificial intelligence converts the 29-point data into a highly realistic 3D animation (digital avatar) that shows the exact offside line and forward part of the attacker’s body. This animation is immediately displayed on giant stadium scoreboards and television receivers, which is a serious improvement in media literacy and acceptance of refereeing decisions.
Wearable technologies
As the competition calendar gets tighter, the biggest enemy of teams is fatigue and muscle injuries. In the 2026 World Cup, the use of electronic performance tracking systems has reached its peak maturity. Major companies have designed smart vests that players wear under their main uniforms. These vests are equipped with advanced locators, 3D accelerometers and heart rate monitors.
The extracted data includes indicators such as total dynamic load, start speed, distance traveled in high-pressure movement zones, and heart rate in recovery phases. By analyzing this data live on their tablets on the bench, the coaching staff of teams such as England and Scotland can replace a player before a muscle tear or hamstring injury occurs. Artificial intelligence connected to these systems by comparing the player’s live data with his historical database, predicts the threshold of dangerous fatigue and warns the coaches.
Evolution in television broadcasting
The experience of watching the 2026 matches has entered a new phase with the introduction of “Rafcam” technology. These lightweight miniature cameras are mounted on referees’ headsets or goggles. The main challenge of this technology in the past was severe image jitter and high data volume for live transmission. However, thanks to the implementation of 5G private networks in all 16 World Cup stadiums, bandwidth and latency are close to zero. The artificial intelligence algorithms located in the transmitter instantly remove the vibrations caused by the running of the referee and allow the viewer to watch the game exactly from the point of view of the referee, at the same speed and in the midst of the physical conflicts of the players.
