Other Solutions Fall Short 1394 c is Expensive

Other Solutions Fall Short • 1394 c is Expensive and Limited – Bridging IP/1394 and IP/Ethernet is costly • Wireless Still Needs Ethernet – Routers often not integrated into the AP – Single AP often times not adequate – Multiple APs interconnect via Ethernet • HPNA and Home. Plug are Still Unreliable – Legacy wiring is temperamental at best • Coax is Not Consumer Friendly July 2004 IEEE 802. 3 CFI Portland July 2004 1
