Abstract

Within a local region, information may be communicated between two or more wireless multimode communication devices (WMCD) comprising 60 GHz band and lower frequency band wireless interfaces, wherein spatial relationships between devices may vary. The 60 GHz interface may handle location determination operations and data transfers. The lower frequency band may support WPAN, WLAN and may handle coordination of communications and data transfers. The WMCDs may be coupled with a network. Antennas may be directional. Moreover, the spatial orientation of the antennas may be dynamically modified or swept across a specified angle. Furthermore, intelligent and/or adaptive antenna systems may be utilized. The WMCDs may utilize a position and/or time reference system to aid in location determination operations.
