Abstract

An apparatus and method of location-based wireless messaging wireless devices is described. The method includes the receipt of a location-based message request from a user of a wireless device desiring to receive a location-based message. Once the request is received, a spatial location of the wireless device is monitored. Once a current spatial location of the wireless device is identified, as a spatial location of a message delivery location, a location-based message is communicated. In one embodiment, a user, via a location-based message request, may request the delivery of the location-based message to a destination wireless device. In a further embodiment, a wireless device may periodically transmit the current spatial location of the wireless device to a predetermined destination wireless device. In a further embodiment, a wireless device may be notified when a selected wireless device is within a predetermined proximity. Other embodiments are described and claimed.
