Abstract
Official abstract text for this publication.
A localized collaboration of wireless communication enabled devices can be provided for sharing of information that is independent of external communications. A local hub can communicate with a remote hub and end users using one or more wireless communication points, and provide for uploading and downloading of collaborative information from the local hub by an end user device. The local hub wirelessly broadcasts a message that has contact information that allows a remote hub to wirelessly retrieve collaborative information from the local hub. The local hub can synchronize collaborative information with a remote hub, if present, by retrieving a remote version of collaborative information using the remote hub's broadcast contact information; comparing the remote version with a locally stored version, if present; updating the local version with differences between the remote version if the remote version is a desired; and creating a local version if one is not present.
