Abstract: Mechanism to mitigate signal interference in ultra wide band (UWB) networks based on spatial reuse of the signal spectrum. Efficient media access control (MAC) in wireless networks is challenging because wireless devices may be affected by signal interference during spatial multiplexing. Wireless ad-hop (multi-hop) networks exploit the limited system bandwidth available via spatial reuse to enhance aggregate throughput. Spatial reuse allows concurrent data exchanges, resulting in higher throughputs.

Abstract: Aspects describe service discovery of wireless MDDI client-capable devices though interaction with an underlying bearer protocol. Service discovery can be performed when the underlying layer supports multicasting, when the underlying layer is wiMedia UWB MAC and/or UDP/IP. Service discovery can be initiated by a w-MDDI sender and/or a w-MDDI receiver. An optional mutual security association procedure can be conducted if both devices support security and security is necessary.

Abstract: Embodiments are described in connection with transferring data traditionally communicated through a wired link over a high-speed wireless link. The disclosed embodiments provide the wired and/or wireless data communication with minimal changes on the existing wired architecture. According to an embodiment is an apparatus for communicating wirelessly over a traditional wired link. The apparatus includes a transmitter comprising a host and a first portion of a client connected by a wired link and a receiver comprising a second portion of the client. According to some embodiments, the apparatus can include a query module that determines an operation rate based in part on a rate supported by a medium access control and a retransmission statistic and an assigner module that assigns a communication to a wired protocol or a wireless protocol.
