The only thing that I see wrong with this is that the cell "tower" needs
to connect to the wired phone system. We know that it can't be hardwired, that would be one hell of a long cable! So, as the "tower" needs to transmit and receive (transceiver) from other transceivers on the ground that are hardwired to the phone system. You can put the ground transceivers on a different frequency pairs, but that's a whole new world wide system! Brian Case wrote: Actually it could work very well, and I have seen this proposal from several different sources. The Idea is to install a low power cell phone tower into the airliner. As I understand it that signal bar you see on you Cell phone is dictates how much power the cell phone uses to transmit. So the closer you are to the tower the less power it uses to transmit. This is why you phone batteries probably last longer in town than the do out in the boondocks. By installing the tower in the aircraft you are only a few hundred feet from the tower (at the most). The Cell phones will get an excellent signal from it and will drop to the lowest transmit power setting, Thus the interference with towers on the ground should be minimal. I am not an expert on these, I am just repeating how it was explained to me. Brian "Morgans" wrote in message ... "Bob Chilcoat" wrote in message ... I noticed on the evening news the other night that someone is trying to get a modular mobile "cell tower" approved that would be installed in commercial aircraft so that passengers can use their own mobile phones. It will be interesting to see how the FCC and FAA handle this one. -- Bob (Chief Pilot, White Knuckle Airways) Still won't work. The frequency the cell in the air is on, will be hitting dozens of towers on the ground, making them unable to use that frequency for other users on the land. |

Well, it would work well, but not if they actually used the cellular frequencies (AMPS). If they installed a PCS processor in the plane, modern PCS phones would communicate with it and not fall back on the AMPS frequencies.

DaveC wrote: Cell phone usage is restricted on all domestic commercial flights by the FAA, so the flight attendant keeps telling me. Nope. The FAA rules have not changed on this, nor have the FCC ones. You can't use Advanced Mobile Phone Service (i.e., traditional cellular) airborne. That is an FCC rule. The FAA rule is just that the airline (i.e., the operator) must determine when electronic devices are safe to use. The only thing that has really changed is the "conventional wisdom" on the FAA's part got a little tighter after some supposed interference issues (primarily blamed on laptops) a few years back. Is cell phone usage also restricted on private jets, etc. for similar reasons? Yes, all airborne use is prohibited. On cell phones permanently installed on private jets, there has to be a warning label attached to prohibit it's use in the air. (FCC rule). So my question... what is the technical reason for restriction of cell phone us on commercial flights? Is this reason valid, technically? Or is it simply an excuse to force anyone who needs to make a call to use the airline's on-board phones (and pay their outrageous rates)? Forcing you to use the Airphones is the least of the FAA's or the FCC's concern. The real reason is that the cellular phone industry does not want you to. Their bread and butter is the ground based caller, and their systems are not designed to work with callers that have some altitude on the system (there are techncial deficiencies in this that I won't go into unless you really want to know). As a matter of fact, the cellular industry fought a company who wanted to share the spectrum tooth-and-nail over airborne use. Oddly, this prohibition is NOT written into the rules for the newer wireless services (PCS, NEXTEL, etc...) that operate outside the AMPS (800MHz) band. However, most of the carriers with these services still discourate airborne use. |

The FCC prohibits using cellular phones on aircraft, but that applies only to cellular phones, few of which exist any more. Most modern 'cellular' phones are in fact PCS phones, which are not subject to that regulation. Actually, they are subject to the regulation when they operate inside the AMPS band regardless of the technology used. Many of the PCS services fall back to AMPS. Some of the other wireless providers do digital service in the AMPS band as well. |
