In Indonesia, terrorists were arrested and tried to fire bomb-backup triggers. The police made a request this week. Explosives were discovered during a raid earlier this month, including a switch mechanism. When the main trigger uses a SIM card and detonates a text message on a mobile phone, the explosive device can use a signal sent over Wi-Fi to detonate these explosives. Wait a second, it’s blocked by an RF jammer.
According to the Straits Times, Brigadier General Dedi Placeto said at a press conference: “He can put bombs in some of his backpacks, and later he will detonate them, for example, only 1 km away “” Yes, we know that Wi-Fi usually does not reach a range of 1 km. We will return soon.
Before the announcement of the presidential election results next week, Indonesia is on high alert. The election was closed in April, and in recent days, the current president ’s main opponent, Prabowo Subianto, held a rally and asked observers to investigate allegations of fraud he committed.
When the election results are announced on May 22, the current President Joko Widodo will be re-elected, and the police will encounter suspicious terrorists in advance: due to the results of the polls, people worry that extremists will be on the streets The protest caused explosives.
According to the police, one of the detainees was a professional bomb manufacturer working on the Wi-Fi trigger mechanism. It is not uncommon for bombs to use Wi-Fi signals-there have been several cases in the Middle East-but this is believed to be the first case outside the region.
More details of the bomb were released by Didi in Jakarta on Thursday. Although the Indonesian police now routinely use signal gps jammer at large public gatherings, in recent years, due to the proliferation of bombs, they have only interfered with mobile phone communications and have not affected radio frequencies.
According to the police, even if Wi-Fi does not transmit certain mobile phone signals, the range can be increased to one kilometer by carefully designing routers and amplifiers. Although this may be news for people dealing with dead ends in their own homes, it is shocking for security forces trying to ensure large areas of overcrowding.
Dedi also complained that it is more difficult to interfere with WLAN signals than mobile radio, which is very undesirable using WLAN activated bombs, although the spokesperson did not elaborate. Indonesian police officers may not have equipment that effectively overflows all different wireless network channels, and the noise is sufficient to disrupt communication. Standard WLANs use the normal number of frequency bands, such as B.900 MHz, 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, 5.9 GHz, and 60 GHz.
The police may turn off the telephone pole to prevent the transmission of messages, which is not possible for the wrong Wi-Fi base station and repeater. The extended Wi-Fi signal may be highly directional or use non-standard radio frequencies, thereby bypassing interference from Southeast Asian countries. Welcome Reg readers to join. If a bomb activated by WiFi becomes a regular threat, we can imagine that people will step up their efforts to develop and use more effective WiFi jammers.
