Conclusions Recommendations

• Although Fiber has all the BW it may not be
  practical
• WLAN, WIMAX and Satellite links look very
  promising
• Wireless links can support all day to day media
  updates
• Initial load may need dedicated time or physical
  media
• Recommendation
• Support portable content load for initial load
  maintenance
• Support Wireless links (WLAN/WiMax/Satellite)
  for daily monthly updates
• 10 to 15 movies upload during a 15 minute at the
  gate
• 40 to 60 movies upload during an hour at the gate
