Most people now have their own cell phones, but using them can make geographic information available to carriers, making our lives very transparent. You already know that pigeons that have returned to Japan can fly long distances, but there are also animals such as the red shrimp that can supplement livestock. Studies have shown that these marine organisms can obtain location information from azimuth cues generated by many local anomalies in the Earth's magnetic field. After installing portable jammer on all Android and iPhone devices, a group of engineers at the University of Oulu in Finland recently introduced a new indoor positioning technology or Bluetooth beacon used by the university that does not require a Wi-Fi hotspot. Developed. team. Some signal processing techniques have found something interesting. A large amount of steel in the building twisted our magnetic planet, bringing unique models throughout the building. Project manager Janne Haverinen explains: “All buildings, building grounds, and corridors generate specific magnetic field interference. You can measure these interferences to easily identify this location and generate interesting maps.
However, the new GPS locator on our website can easily solve this problem. However, some signal processing techniques used by this university team have found something interesting. Each location in the building has its own model, as the large amount of steel in the building distorted the magnetic field of our planet. Project manager Janne Haverinen explains: "Every building, the ground of a building, a corridor produces certain magnetic interference. You can measure these signal jammer to easily identify this location and generate an interesting map. But our web The new GPS locator on the site can easily solve this problem. "However, some signal processing techniques used by the university's team have found something interesting. The large amount of steel in the building distorted the magnetic field of our planet, creating unique models everywhere in the building.
