As many as 20,000 wireless frequencies will need to be assigned to cope with demand created by the Olympic Games, says Ofcom.

According to the regulator, careful management of London's airwaves will be essential for the coverage and organisation of the event, which will take place this summer, as not only will timing and scoring system need wireless connections but they'll also be a demand from broadcasters for the likes of wireless cameras and wireless microphones. Furthermore, Ofcom said the figure is more than double the number usually assigned in a year.

However, Ofcom says it has developed a plan to secure additional capacity. This will include borrowing spectrum on a short-term basis from public sector bodies, such as the Ministry of Defence, utilising currently unused frequencies of the civil spectrum, along with the spectrum freed up by the digital switchover and those that can be used without the need for a licence.

Furthermore, interference will be kept to a minimum through a "state-of-the-art spectrum assignment system" that will be used to "manage access to spectrum, keeping it both free for those who need it and free of interference".

"The UK's airwaves are already among the most intensively used in the world. The London 2012 Games will significantly increase demand," said Ofcom's Chief Operating Officer, Jill Ainscough.

"Ready and prepared for this challenge, Ofcom recognises that there is no room for complacency. We are working behind the scenes to make this capacity available, to ensure that this demand is met."
