From doing research on this topic earlier this year, I came across news
The FCC prohibits communication using a cellular telephone while in an aircraft in US airspace. In Canada, I don't believe there is such a regulation. articles that say that several aircraft manufacturers have tested the use of cellular telephones on aircraft systems and found no effects whatsoever. So why the FCC ruling? Likely it's because of the design of the cellular network - which from what I understand, is far more dense in the US than it is in Canada (which might be why the CRTC doesn't have such a prohibition). The problem is what happens when a cellular device is based above the cellular system antennae - there is an ability to connect to multiple systems simultaneously, and that's something the system wasn't designed to see happen. Additionally, there's the hand-off factor, of the negotiation process of what happens when you leave the range of one cellular tower and enter the range of another. In an aircraft, that happens at a rate greater than would be if the cellular phone were used in a car - so again, there's a problem there. The Airphone system found on commercial aircraft was designed to overcome these limitations - which is why they CAN be used onboard commercial aircraft systems. So, besides it being illegal, you run the risk of taking down your service provider's cellular network - and from what I've heard, this doesn't make them very happy. In summary - don't do it. -- Leigh Anne Chisholm Network Engineer Applied Design Networks

Nearly all aircraft have AM radios in them (it's called the ADF), so I'd be surprised if those caused interference :) Boeing and the FAA did thousands of hours of testing and were unable to cause any avionics of any vintage to malfunction when cell phones et al were in use inside the cabin. The official position is that personal electronic devices produce interference levels above the certified minimum tolerance levels of avionics. Even if the avionics can withstand higher interference, they're still being operated outside their certification and that's illegal. There do exist telephone and datalink systems which are certified for use aboard aircraft (private or commercial). However, I doubt you'll be interested when you see the cost.
Think it was a similar thing in hospitals.. ?
I was in an ER a couple days ago; the laptop computers in the halls used 802.11b and the doctors carried standard cell phones. If there was a problem in the past, it's not around any more. Similarly, HDTV broadcasts took down a lot of pacemakers when they first cranked up; the affected units have either all been replaced or killed their owner -- problem solved. S

The problem isn't logging, billing, or crashing the network. The problem is that the Cells are designed to have a certain area of coverage based on the assumption that the remote station is a ground-based station. When you elevate a station, that station becomes capable of transmitting it's signal significantly further, as the horizon expands and obstructions are reduced. Thus, instead of bringing up a small number of cells from the ground that are expecting a certain amount of co-channel interferrence from each other and from stations that are between them, you can occupy the channel on a large number of cells that are not expecting a single phone to hit all of them. Bottom line, it's kind of like spewing a flood ping into the net over a T1. You aren't going to crash the network, but you're sure using a lot more bandwidth than expected, and you're wasting bandwidth that could be used by others. Hope that clarifies it. Owen P.S. It's against FCC, not FAA regulations, although there are also FAA regulations that prohibit the use of a transmitting or receiving device on a part 121 air carrier unless the pilot gives informed consent. Further, the FCC regulation prohibits the use of a cell phone while the aircraft's wheels are not in contact with the ground. Jacob M Wilkens wrote:

Yo Jacob! Billing has nothing to do with it. If there is one thing Cell Phone networks get right it is billing. The problem is frequency re-use. For old style Analog cell phones there are only just over 300 chennels per carrier. No problem because cell phones are line of sight and you can not see very far in your car. So in a big city like SF, the same frequencies are reused every few miles. Get in an airplane, fly over SF bay, make a cell call and one frequency is used up for the whole bay. If everyone on one 747 did that then all the frequencies would be used up and no-one else could get on. On Thu, 27 Jun 2002, Jacob M Wilkens wrote:

Boeing has repeatedly stated that it is not stupid enough to make airplanes that will fail because someone in the back has an electronic device on. Ossama would love that if it were so. It is the FCC, or the individual airline that bans electronic devices, not the FAA. The FCC bans most (not all!) cell phone in flight because cell phones are line of sight. So on in-flight cell phone ties up a LOT of cell towers on the ground. Air ambulances routinely ignore this rule and I am sure a lot of people are alive today because they do. One of the airborne certified vendors of airborne cellular is AirCell: http://www.aircell.com Garmin sells the NavTalk Pilot which is a combination GPS, ground cell phone and airborne cell phone: http://www.garmin.com/products/navTalkPilot/ GTE Airfone is a ground based phone TSOed (a.k.a. certified) for in flight use in small airplanes. They are at: http://www.airfone.com Being ground based it does not have the latency problems of Sat Phones. The bad part is in only works when you are in the air. The airline bans electronic devices just to shut up the little old ladies. My favorite is "please turn off you PDA for takeoff". Huh? All the On/Off sitch on the PDA does is turn off the screen...

Yo Scott! Several services will do what you want. They are ALL expensive. One of them is Orbcomm: http://www.orbcomm.com They have several FAA TSOed (a.k.a. certified) redios for aircraft usage. With Orbcomm you can send and receive email, weather fax, etc. Echo Flight is one reseller of Orbcomm service to small airplanes: http://www.echoflight.com There service is $10/month plus $1/email The FAA is currently funding several competing data-link projects. The idea is to force vendors to give away basic services to all airplanes and be allowed to charge for premium services like email. Details at: http://www.avweb.com/oshkosh/osh99/day5/fis/index.html Icarus has their "SatTalk II" phone. It allows cell phone like connections while inflight.

In the event of an in-flight radio communications failure, and only after normal communications failure procedures have been followed (see RAC 6.3.2.1), the pilot-in-command may attempt to contact the appropriate NAV CANADA ATS unit by means of a cellular phone. Before the pilot begins using a cellular phone to contact ATS in the event of an in-flight communications failure, transponder-equipped aircraft should squawk Code 7600 (see RAC 1.10.7).
This at least suggests that there's no CRTC restriction on using cellular telephones from altitude (or that any such CRTC restrictions can be overriden by Transport Canada). Joe
Since when did any Canadian Federal Government department do anything that corresponds with the policy of other Canadian Federal departments? (-: I know several pilots that have left their phones on while in flight - or that have used them "because they can". They haven't experienced the effects others in the US have reported - and again, likely due to the less-dense nature of the Canadian cellular network. You found something in the AIP? Well yes, I found that too, but these days that's been the ONLY thing I've been able to find. Oh...

A slight addition to this (maybe OT) thread but my wife was being medivac'd on a small jet to a larger medical facility a few years ago, one of the medical fellows on board used his cell phone a couple of times on board while in flight. I asked him about that and he said it was no problem and he said there was no restriction as far as he knew. As long as there was service he could use the phone. It was a big clunky Motorola brick phone. But the plane/medivac is part of the provincial ambulance service so rules might be different in this case, compared to commercial aviation. Keith |->Joe

"as far as he knew" -- You really think a paramedic (who just happens to be in a helo that day) knows the intricacies of cellular telephone regulations and how they change when airborne? I think he's a bit more concerned about how to keep his patients alive.
But the plane/medivac is part of the provincial ambulance service so rules might be different in this case, compared to commercial aviation.
"Lifeguard" flights get priority treatment by ATC, but they are not specifically exempted from any aviation or radio regulations. That said, both the aviation and radio regulations have blanket exemptions for any otherwise prohibited activity which is necessary for the preservation of life. This means that if someone's life is in danger, be it yours or a medivac patient's, anything reasonable goes. S

The GTE airfones installed in most large planes have data ports if you must connect a computer. But be prepared to pay a very steep per-minute charge for the connection. -- David
This probably isn't certified for flight use, but: http://www.kvh.com/products/product.asp?id=60 would provide the uplink with usable bandwidth. The downlink requires: http://www.kvh.com/products/product.asp?id=13 for auto tracking. Tony (who is not affiliated in any way with the manufacturer)

I was wondering if any of y'all could give me pointers to services I could use to log into a network during flight on a private airplane. For example a person is in flight cross-country and needs to do a videoconference, send email from his network to interested parties, or any of the normal things we do from the ground. Is this possible or would it interfere with the plane's other systems?
