Abstract
A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As other example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.
