PRIMEX Aerospace Company Page 8 USB l Connector type: USB l Laptop cable: Standard USB cable l Hardware requirements: Virtually all laptops come with built-in USB ports (replacing many other I/O options) l Maximum speed: 12Mbps l Industry Acceptance: High and growing fast, now available in several hotels l Ease of use for passengers: “Plug and Play”

9. PRIMEX Aerospace Company Page 9 Summary l Telephone modem: Easy to use, widely deployed, limited bandwidth l Ethernet: Difficult to use, available today, high bandwidth l Serial Port: Easy to use, future in question, limited bandwidth l Wireless: No cables, difficult to use, not widely accepted, high bandwidth? l USB: Easy to use, comes standard with all new laptops, high bandwidth

10. PRIMEX Aerospace Company Page 10 Cabin Distribution A Passenger’s Perspective l Passenger doesn’t care how just that his/her level of service is maintained. l Adequate bandwidth (> 1.5Mbps) must be guaranteed for each passenger to meet the demand of Internet services for several years out

11. PRIMEX Aerospace Company Page 11 Gaining Passenger Acceptance l Must be deployed rapidly to meet customer expectations that the service is available wherever they need it l To do this the airlines need a system that is:  Low weight  Low power  Small form factor  Easy to install
