Abstract: A user may be matched to a community or another user based on travel information such as destination, route, time to arrival and the like. Thus, a user traveling to a destination may be able to communicate with or meet other users traveling to the same destination. Other information may also be used in determining matches including habits, interests or relationship status. In one arrangement, travel information may automatically be obtained from a navigation engine while a user is traveling. The travel information may be automatically sent from the navigation engine or a communication system associated therewith to a server configured for identifying matches between users or between users and communities. A user may further set a match threshold to control the number of matches that are returned. Recommendations for restaurants, activities, hotels and the like may also be determined based on the history and profile of matching users.

Abstract: A method comprising determining information for the performance of a channel and sending the determined information to a transmitter is disclosed. The determined information can be sent to the transmitter with acknowledgement data. The determined information can include, for example, data rate and/or transmit power. The acknowledgement data can be sent in an acknowledgement frame, such as a block acknowledgement frame or immediate acknowledgement frame. The determined information can be sent in the payload of the frame. The frame can, for example, be a kink feedback frame associated only with a particular transmitter and receiver. A characteristic of the channel, such as signal and interference to noise ratio, can also be determined.
