What is Phase Two?

Field tests. These will take place in a football stadium chosen by the technology system provider. Testers will conduct a greater volume of shots on an empty goal, shots against an impact wall, shots on a goalkeeper, and the sled test, also used on Phase 1 testing, where a ball is placed on a sledge and moved along the goal-line. Training sessions . A series of simulated scenarios on the field using players will assess the systems with an increased number of players in and around the goalmouth. Laboratory tests. Both systems will be tested against a variety of conditions. This will include simulating different climatic conditions (including rain, smoke/fog and heat/humidity), testing against the impact of proximity to mobile phone transmitters or other magnetic field distortions (eg TV cameras, LED advertising boards) and tests on the watches which would be worn by the match officials. Real 'live' matches . To ensure that every eventuality has been considered in the two testing phases, each company is also required to have its system tested in two separate 'live' matches.
