Accuracy is another concern. Although GPS technology provides location information, the locator device still depends on cellular phone technology to transmit the information. Poor cellular coverage areas may decrease the device’s usefulness. More importantly, because GPS devices require a clear view of the sky to access the satellites, they do not work indoors. Thus, a patient must have escaped the house for the device to work.
