A wireless event notification system that selectively notifies members of events based on their location and/or interests, and devices and method for use therein. The wireless event notification system provides single or multifactor filtering based on one or more of proximity to an event, membership in a subgroup to which an event pertains and/or desire to receive events at the severity level of an event. Superfluous notifications are thereby reduced. Location-based filtering may be done by a notification server device to which member locations are reported or, to enhance member privacy, by wireless client devices using unreported member locations. Additionally, in some embodiments, wireless client devices are distributed by a system administrator to members after the system administrator has registered the members with the system to remove device acquisition, device compatibility and member registration hurdles that can present obstacles to universal participation in the system.
