Abstract:
A system for leaving and accessing messages at coordinate way points, the system comprising:a commercial mobile radio service provider network; a plurality of subscriber devices to said commercial mobile radio service provider network; at least one user interface inherent to said devices for facilitating two-way communication with said network, said devices each possessing a unique identification number; said interface and said device adapted to permit operations selected from the group consisting of capturing said device's own instant coordinate location, leaving a message associated with a specific coordinate location within said network, accessing a message posted at a specific coordinate location within said network at least due to said user device's physical proximity to said specific coordinate location, and mixtures thereof, wherein leaving a message associated with a specific coordinate location requires said user to specify at least a location associated with said message but does not require an explicit recipient; a distributed data management server connected to said commercial radio service provider network; hardware executing software enabling said network and said server to know in near-real time the coordinate location of said devices within an area of influence defined by said network.
