According to Filip Technologies, the FiLIP 2 uses cell tower location and Wi-Fi triangulation to supplement GPS data, which can more accurately pinpoint a child's location in areas where GPS is limited. Further enhancing its effectiveness, the FiLIP 2's cellular technology also enables parents and children to communicate with each other using two-way voice functionality to place and receive calls. We worked closely with Filip Technologies on this amazing new product, and we are very excited for the FiLIP 2 and its young customers," said Walter Ripple, vice president and general manager, for PolyOne's GLS business unit.
