UWB's wide bandwidth capacity enables multiple wireless connections simultaneously. Low-power UWB transmissions support high density clustered connections in the immediate proximity, such as a living room, but not producing interference to other devices outside the room. When extended range is required for applications such as TV broadcasting covering the entire house, WiNet could provide wireless bridging capabilities to extend the necessary communications range. ASTRI's patent-pending multi-hop technologies provide additional advanced QoS features complimentary to WiNet's capabilities.

ASTRI is developing advanced UWB technologies in consistent with SMP and WiNet protocols to support home multimedia network standards, such as IGRS and DLNA. Specific R&D efforts are also put in system integration and applications development for wireless CE products, supporting both stand-alone and embedded designs by using widely deployed industry interfaces such as SPI, PCI, and SDIO. Depicted in Figure 1 is an illustration of UWB technology application for wireless video streaming involving video compression and decompression capabilities.
