Terrorists have been caught strapping Wi-Fi-activated backup triggers to bombs in Indonesia, police claimed this week.
The explosives were discovered in a raid earlier this month, and included a switching mechanism that enabled them to be detonated using a signal sent via Wi-Fi if the main trigger, which uses a SIM card and waits for a mobile phone message to detonate, was blocked by radio-frequency jammers.
"With that, he can put [the bombs] in some backpacks, and later he would just detonate them from a distance of 1km, for example," said Brigadier-General Dedi Prasetyo at a press conference, according to The Strait Times.

Even though Wi-Fi will not travel as far as some cellphone signals, the police said that a careful construction of routers and amplifiers can extend the range as far as one kilometer. Which, while it may be news to people that deal with dead spots in their own house, is alarming to security forces trying to secure large areas full of people.
It might be fun to try infrasound, too.

Why don't they set it up whenever they get a signal on the police frequency? That way nobody has to wait around to set it off.
I know! Mines are banned by international agreement.

Did you have to remind me that the US is once again in great company, on the list of countries refusing to sign the ban ?
