The space may be defined by one or more parameters set by the sending device. A wireless PAN may define the range of peer-to-peer transmission and reception of radio waves between at least two wireless devices. Location and orientation information may be transmitted by a communication device and combined with user and/or software defined boundary limits to filter short range wireless messages. ## Claims ### Claim 1 A method for targeted transmission of a communication, comprising: receiving an event to initiate transmission of a communication;
