Abstract

Methods and systems of indoor positioning of a user and delivery of information thereto are described. A system may include a communication device and a plurality of networked devices. The communication device may receive incoming information which is intended for receipt by a user, and transmit a request signal responsive to the receiving of the incoming information. Each of the networked devices may receive the request signal, and determine which one of the networked devices is situated to notify the user of the incoming information. The networked device situated to notify the user may proceed to notify the user of the incoming information.
