Do we need it?
What data rates do we need?
Is it possible?
HD wireless video distribution

60 GHz Technology
L band 1 to 2 GHz
S band 2 to 4 GHz
C band 4 to 8 GHz
X band 8 to 12 GHz
Ku band 12 to 18 GHz
K band 18 to 26.5 GHz
Ka band 26.5 to 40 GHz
Q band 30 to 50 GHz
U band 40 to 60 GHz
V band 50 to 75 GHz
E band 60 to 90 GHz
• Compared to WiFi– 200 times as much spectrum– 50 times the capacity
• SiBEAM– 4 GBps, uncompressed HDMI

I don’t want to discourage you, but ….
Emerging standards probably not scalable to 100s of seats.
Complete blockage by human bodies, drink carts
Power Consumption (Gigabit data rates)
16
Ka-band
Much Lower Cost per Bit than Ku or L
• Spot beam coverage
• More spectrum
Less complex antenna (than Ku)
• No polarization steering required
More difficult steering problem
• Can be resolved
17
Only Regional Coverage at Ka-band
Need Ku to cover the oceans?
It’s hard enough to pay for one broadband antenna.
Regional Ka-band competes with Air-to-Ground• tough competition!

Ka-band Rain Fades

Gary’s Long Term Outlook• Wireless HD video distribution at
60 GHz can probably be made to work, but will keep folks like me busy for a long time.
• The technical problems at Ka-band can be solved, and can make passenger communications much more affordable. They are definitely worth solving if a global Ka network is built.
