Mobile phone signal jammer is used in Chengdu Huawei Mobile Cup China Go League from dojammer's blog

Cell phone signal jammers are used more and more. In addition to the general test site, they are also used frequently in competition sites from all walks of life. The 2022 Huawei Mobile Cup China Go League One, which is currently being held in Chengdu, has adopted a number of anti-cheating measures, and installed a mobile phone signal jammer in the bathroom for the first time to cut off the possibility of AI cheating from the source.

According to the relevant regulations of the Go competition, players must take out their mobile phones before entering the arena and hand them over to the staff for safekeeping. This year's Siege League matches are played in the same hotel as the chess players' land, and chess players are required to leave their mobile phones in the room as required and are not allowed to bring them into the arena.

Like most Go tournaments, this year Siege installed a security gate at the entrance of the arena. Players must go through security checks before entering the arena. Once the alarm sounds, the staff will check it by hand, and the players can enter the arena only after confirming that it is correct.

In addition to conventional security measures such as security gates and surveillance cameras, there are also full-time referees on site to supervise and patrol the Siege League. During the game, all chess players are not allowed to leave the arena area, and are limited to activities in the arena and toilet area. Once a chess player is found to return to the room privately during the game, he will be sentenced to lose.

In addition to strict requirements for chess players, team leaders, coaches, media and other relevant personnel must leave the arena 30 minutes after the start of the game. Even for the rapid chess match that started at 13:00 that day, relevant personnel were no longer allowed to enter the arena.

Unlike most sports, a game of Go usually takes five or six hours to play. During this period, players will drink tea and coffee to refresh themselves, and it is inevitable to go to the bathroom several times. In the AI era, there have been chess players cheating in the bathroom. However, in view of the violation of personal freedom and the cost of installing signal jammers, few events have adopted relevant anti-AI cheating measures in the bathroom before.

For this year's Siege League, the organizer Chengdu Chess Academy installed mobile phone signal jammers in the bathroom of the arena. After entering the bathroom, the mobile phone signal disappears immediately, and you cannot access the Internet or make calls, cutting off the possibility of AI cheating from the source. According to relevant staff, mobile phone signal jammers will become one of the conventional means of preventing cheating in Go games in the future, so as to avoid cheating as much as possible.
