Method and apparatus for wireless tracking and communication |
摘要 |
A positional tracking system including a mobile unit is disclosed which may be disposed in a pre-determined coverage area, such as an amusement park. The mobile unit may send an alert message to a dispatch center or parent units if the mobile unit enters locations defined by forbidden coordinates. The mobile unit may function only within the a coverage area, and thus park patrons will have little incentive to remove mobile units from the coverage area. A dispatch center may determine when the mobile unit leaves the coverage area and notify a parent unit. Additionally, the mobile unit can automatically sound an audible alert when leaving the coverage area.
