Both mobile telephony and Wi-Fi internet access play growing roles in the nation's use of wireless communications.
However, if a central cyber attack were to succeed, much of the cordless network could be crippled, potentially leaving landlines and wired internet connections as the only means of electronic communication.
This week, prime minister David Cameron announced £500 million of investment into protecting against such threats.
He said: "This will significantly enhance our ability to detect and defend against cyber attacks and fix shortfalls in the critical cyber infrastructure on which the whole country now depends."
William Beer, director of OneSecurity at PricewaterhouseCoopers, responded by explaining that much of the nation's exposure to risk arises from a lack of talented individuals to protect its electronic systems.
Investment will help to build the "army of prize troops" he says is required in order to fight "the cyber war".
