For the 2012 Olympics, London, which already had a large number of security cameras, did everything from install surface-to-air missiles to surveillance systems for infectious diseases. One of the most important innovations for the Olympic Games, however, is probably the introduction of the Apollo network. For the first time in Olympic history, Private Mobile Services Radio provider is a sponsorship category. Airwave, the company that built the Airwave Network, in use by London emergency services since the emergency communications debacle of the 2005 bombings of the London Underground, is the official sponsor in that category. For the London Olympic Games, Airwave built a completely new communications network, called the Apollo Network, that was separate from the existing emergency services Airwave network. This network ensures communication across London with no interference from other radio systems. Airwave also improved the existing emergency services radio network, increasing its capacity, especially in the areas where security would be of bigger concern.

Radio communication was first proposed in London after the mobile phone network, which had been the primary emergency communications system, was overloaded during the aftermath of the bombing of the London Underground. Since then, the Airwave radio network, implemented in 2006 as the Connect Project, has proven to be exceptional, especially underground, and secure and efficient. The Airwave network was tested by a real emergency situation in during the 2011 riots. This made the network ideal for the increased security measures taken for the Olympic Games, although a separate network was required in order to retain the same levels of efficiency and resilience.
