Qatar: FIFA’s testbed for match tech and replay systems, 2021-2025

Qatar became the proving ground for many of the match technologies now underpinning the 2026 FIFA World Cup, with trials running from the FIFA Arab Cup 2021 through experiments in 2024 and 2025. Systems tested on Qatari pitches ranged from optical player tracking and a connected ball to referee bodycams and real-time 3D re-creation.

What did Qatar trial and when?

Qatar hosted staged rollouts and full-scale trials beginning with the FIFA Arab Cup 2021 and continuing through multiple events up to 2025. The sequence in the source text: the Arab Cup 2021 saw several systems tested together at scale; the Al Rihla connected ball and semiautomated offside were visible at the 2022 World Cup after earlier trials; a headset-mounted referee bodycam appeared at the 2024 FIFA Intercontinental Cup; out-of-bounds detection and real-time 3D re-creation debuted at the 2025 Intercontinental Cup; and a simplified Video Support System was tested at the 2025 FIFA U-17 World Cup in Qatar.

The country’s planning apparatus dates back further: Qatar’s Supreme Committee for Delivery and Legacy was formed in 2011 to oversee infrastructure for the 2022 World Cup, and its executive director Thani Al Zarraa said, “Since the FIFA Arab Cup 2021, we have done more than host football’s biggest matches; we have helped shape how the game is played, officiated and experienced.”

How do the key systems work?

Optical player tracking uses high-precision stadium cameras that capture every player’s movement dozens of times per second with centimeter accuracy, forming the foundation for faster officiating and richer performance data. A connected ball carries a sensor suspended at its center; Adidas first trialed connected-ball technology during the FIFA Arab Cup before introducing the Al Rihla at the 2022 World Cup, and the ball’s inertial sensor has been used to verify touches and the precise moment a pass was played.

Semiautomated offside systems combined those feeds to cut decision times from minutes to near-instant calls at the 2022 tournament. Coaches and analysts received live feeds via dedicated analyst workspaces and replay tablets, giving staff immediate tactical and performance information during matches. The FIFA Player App, rolled out early in 2022 and built in partnership with FIFPRO, delivered players their own positional heat maps and physical-output data often within minutes of the final whistle.

Referee-facing innovations moved in parallel. A headset-mounted camera trialed in 2024 offered spectators the referee’s perspective. In 2025, out-of-bounds detection used the same tracking infrastructure to decide whether the ball had fully left play, while real-time 3D re-creation converted incidents into virtual models for referees and broadcast audiences to inspect.

Why it matters

Qatar’s role reduced the gap between lab prototypes and stadium deployment by exposing systems to real-match complexity: packed stands, broadcast demands, and split-second decisions. That exposure forced integration between tracking, ball sensors, VAR feeds and broadcast tools, producing tools — such as semiautomated offside and real-time 3D re-creation — that operate at broadcast pace and can scale to major tournaments. The visible effect is faster, more verifiable officiating and broader access to performance data for players and coaches.

What to watch

Watch whether FIFA expands video support and simplified review systems beyond elite events, following the 2025 U-17 World Cup trial in Qatar. Also watch how federations cope with the infrastructure demands of optical tracking and the data streams those systems produce, and note that FIFA staff tested goal-line technology at SoFi Stadium on June 9, 2026, indicating continued rollout and refinement outside Qatar.
