Why does Bluespan use wireless technology and not GPS or cell towers?
Ask yourself: how many times have my cell calls been lost or dropped? Cell towers cannot be found everywhere in the U.S. And they don’t always provide a consistent and strong signal. Global Positioning System (GPS) signals cannot penetrate roofs of buildings, and they don’t generally work as well in areas like cities, where tall buildings can block signals. Bluespan created a system that works in shopping centers, airports, malls and theme parks. Bluespan’s ionTechnology and ionKids products do not rely on cell towers or satellites to locate your child – so cloud cover or a building’s roof will not prevent you from finding your loved ones. 8.
