| 20090059890 | Spatial reuse in directional antenna systems - In directional antennas, spatial reuse involves enabling two communications to occur on the same link at the same time. The communications may be in the same or opposite directions. If no link of sufficient bandwidth is available that does not already have an active communication, a link with an active communication of sufficient bandwidth is located. Then an antenna training sequence may be implemented. A check determines whether the antenna training sequence was successful. If there was interference during the antenna training sequence, then the spatial reuse is not permitted. Otherwise, spatial reuse may be permitted. | 03-05-2009 |
