"Wireless world" seems to be a misnomer here, it seems they’re talking more about the Internet-connected world instead:

Canada’s spies risk going "deaf and blind" from the explosion of new wireless and other Internet advances that make it increasingly difficult to intercept terrorist communications, the country’s spymaster warned Friday.

The fast pace of technological advancement, particularly in telecommunications, is harming the ability of national security agents and police to conduct court-approved electronic eavesdropping on suspected terrorists, said Jim Judd, director of the Canadian Security Intelligence Service.

"We increasingly risk going deaf and blind in an environment where telecommunication providers regularly change their systems in the interests of improving service but in the process can literally leave us out of the loop on intercepts," he told a Canadian Association for Security and Intelligence Studies conference in Ottawa.

Judd said the situation will only worsen with the availability of more and more wireless Internet access and Internet-driven phone systems (Voice-over Internet Protocol or VoIP), which are increasingly popular with terrorists who believe those transmissions are more technically difficult to tap.
