Korea&#8217;s new &#8220;spectrum analyzer&#8221; may be a surveillance tool"},"content":{"rendered":"<p><span style=\"font-weight: 400;\">North Korea has allegedly developed its own version of what is called a \u201cspectrum analyzer.\u201d Daily NK sources suspect that the device, which was presented as a \u201cTop 10 tech product\u201d at the \u201c2019 National Information Technology Advancement Exposition,\u201d could be used to spy on North Korean citizens.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On Monday, Daily NK spoke to an expert in the field of radio waves, who asked to remain anonymous. \u201cIt\u2019s essentially possible to detect and track wireless signals &#8211; frequencies &#8211; with a spectrum analyzer,\u201d he said.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Simply explained, a spectrum analyzer is a piece of electronic equipment which measures the magnitude of known and unknown input signal set against the full frequency range of the instrument.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The specialist was not able to determine how advanced North Korea\u2019s latest development really is. Nevertheless, he thought it\u2019s possible the device \u201cmight even be used to wiretap calls on mobile phones.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Other experts also agreed that the analyzer could be capable of detecting data transmission signals, which most North Koreans send out during a wireless communication.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s no secret that the state has long been intercepting the wireless communications devices of its citizens. Most surveillance equipment was previously imported from abroad. Now, however, North Korea has apparently managed to develop and manufacture similar instruments of its own.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The country\u2019s citizens thus might have to adjust to an even tighter surveillance system soon. North Korea has furthermore deepened this suspicion by announcing the launch of a new artificial intelligence-based video surveillance system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A MILESTONE FOR THE KIM JONG UN REGIME?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Spectrum analyzers can, moreover, play a role in the research, design and production of other electronic devices. \u201cThe analyzer has a powerful corrective ability,\u201d the North Korean propaganda service \u201cMaeari\u201d stated on Nov. 22. \u201cIt guarantees reliance and precision in the detection of signals, regardless of the kind of frequencies and surrounding conditions.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Maeari further claimed the state\u2019s new device was primarily intended to \u201cdemodulate even modulated sonic signals and play the original audio in real time.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The technological breakthrough could thus be a milestone for the Kim Jong Un regime, which has long been trying to advance the information technology and high-tech equipment industry in North Korea.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">North Korea might be looking to develop their spectrum analyzers without any support from foreign suppliers to circumvent the trade sanctions imposed by the international community, which also affect the import of electronic products to North Korea.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">TOO SOON TO TELL<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sources further interpreted the efforts of the regime as a way to substantially reduce its expenditures. As Daily NK reported last year, North Korea spent approximately RMB 15 million (KRW 2.45 billion) on state-of-the-art jammers as well as bugging devices for mobile phones.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cOther countries develop spectrum analyzers, too, but are unable to make full use of their potential due to the immense production costs,\u201d the propaganda outlet Maeari claimed.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">North Korea, according to Maeari, thus \u201chas developed the spectrum analyzer from scratch &#8211; we have defined it anew &#8211; and we only use our own technology and abilities, all the way from its design to its production.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Maeari&#8217;s claims lined up with calls by North Korea\u2019s leader Kim Jong Un for more self-reliance as well as for a greater focus on the domestic production of technology.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The radio expert consulted by Daily NK, in contrast, considered the elation of the North Korean regime a little premature. \u201cIt\u2019s going to be a long way until the spectrum analyzer will be fully developed,\u201d he said.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Manufacturing the device is actually quite simple as it mainly \u201crequires fairly common technologies,\u201d according to the source. However, some components &#8211; those needed to detect high frequencies, for example &#8211; are technically more advanced &#8211; and thus harder to come by.<\/span><\/p>\n<p><em>Translated by Violet Kim and edited by Laura Geigenberger<\/em><\/p>\n<p><i>Please direct any comments or questions about this article to dailynkenglish@uni-media.net.<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>North Korea has allegedly developed its own version of what is called a \u201cspectrum analyzer.\u201d Daily NK sources suspect that the device, which was presented as a \u201cTop 10 tech product\u201d at the \u201c2019 National Information Technology Advancement Exposition,\u201d could be used to spy on North Korean citizens.
