| Freq
The freq that the airlines use are close to the analog cell phone freq. However new cell phones that are digital are not even close. The same goes for Wi-Fi.
Garage door openers, alarm systems, etc. - Around 40 megahertz
Standard cordless phones: Bands from 40 to 50 megahertz
Baby monitors: 49 megahertz
Radio controlled airplanes: Around 72 megahertz, which is different from...
Radio controlled cars: Around 75 megahertz
Wildlife tracking collars: 215 to 220 megahertz
MIR space station: 145 megahertz and 437 megahertz
Cell phones: 824 to 849 megahertz
New 900-MHz cordless phones: Obviously around 900 megahertz!
Air traffic control radar: 960 to 1,215 megahertz
Global Positioning System: 1,227 and 1,575 megahertz
Deep space radio communications: 2290 megahertz to 2300 megahertz |

| The Garage Door frequency is wrong. It is around 390 MHZ to 400 MHZ which is in a military frequency allocation of 225 MHZ to 400 MHZ which is why certain military operations have jammed garage door openers and made garage doors open and close randomly.

What world do you live in? 900 MHz phones are far from new; in fact, they're old!

what is NOT known is how is how these In-Flight Wi-Fi
will effect,the airlines private company radio signals,or its radar or other frequesncies between plane & ground until they are tried, then the "old man" has the option to ban them on when on board.
