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

FCC Regulations

15

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.
