Some 40,000 golf fans are expected to attend each day of the 36th Ryder Cup tournament between Europe and the United States at the K Club near Dublin on Sept. 22-24, amid tight competition restrictions and even tighter security.

"Mobile phones are banned for all six days of the tournament (three practice days and three tournament days)," a spokesman for the European Tour said.

"This decision was taken to ensure that the matches take place without the risk of disturbance to the players."

He said cameras would be permitted on practice days -- Sept. 19-21 -- but not on match days.

Roads within a five-mile radius of the course will be closed off for the entire week, with spectators having to use two special park-and-ride facilities.

Fans will also be subject to security checks on entry, with a passport required for identification.

The spokesman said tickets -- which cost from 35 euros ($44.92) for practice days to 130 euros for the final Sunday -- were non-transferable and non-refundable.

Security at the event will be undertaken by the Irish police.

Irish media reports have said a no-fly zone will be in operation above the course given the number of helicopter trips expected to be taken by wealthy fans during the week but the European Tour was unable to give details.

The event is expected to generate more than 130 million euros for the local economy.
