Other Solutions Fall Short
• 1394c 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 HomePlug are Still Unreliable
– Legacy wiring is temperamental at best
• Coax is Not Consumer Friendly
