Technology Breakthrough

• Jitter-less, isochronous Media Access Control (MAC) layer that is optimized for high payload efficiency (> 80%) with guaranteed QoS for real time video
• Advanced space-time diversity technology (MIMO) that ensures robust links in hostile in-door environments
• Innovative 5 GHz radio architecture that delivers high performance with low-cost CMOS implementation
• Enhanced radio resource control including dynamic channel selection and rate/power adaptation ensures the link quality even in dense deployment case
• Optimal embedded system design for host-less applications such as televisions
• Isochronous interfaces that support standard MPEG transport stream (MPEG2, MPEG4 and H.264)
• Intrinsic advantages of 5 GHz spectrum over 2.4 GHz spectrum: cleaner, more channel selection, easier for exploring space-time diversity technology
