The construction, transportation, and health care industries are among those with high levels of interest in GPS-type technology. Indoor positioning technology offers wireless location services on mobile devices for locating objects or people when inside a building, according to Fieldlens.com. It can encompass a variety of evolving technologies, such as beacons that send out signals that communicate with Bluetooth technology, Wi-Fi signals, or cell towers. “Indoor positioning can also be set up using lights, where LED light fixtures are used to communicate, or magnetic fields, where a building’s internal magnetic field is used for determining location. Even cameras can be configured for indoor positioning,” writes Angela Hurni. In a construction scenario, Hurni says mobile devices that automatically know their location in a building could make it easier to get the right information to the right people on the jobsite.
