useing mobile phones on planes are not allowed.. Why ?

Do you know why the phones are not allowed on airplanes in flight? One reason is the channel reuse. In fact, if we go to the art it would be very difficult for us to understand the many techniques of Mumbo Jumbo, which you can just leave us on the easiest method of reporting that we can. You see, our phones are designed for low power applications. This is because the transmission and reception of signals on channel reuse. What I think about the chain of words, different frequencies, using a mobile phone to transmit and receive signals, eg 120 kHz or 100 MHz. These frequency channels are in Hertz. A mobile phone on 100 MHz. is interrupted signal if another phone, which on the same channel is the same cell or the tower.

Regarding the cell sites or towers, I think you're more or less already in particular. They are very small, like the Eiffel Tower, such as construction, you can see, Jütting landscape of the farm, sometimes even in cities and urban areas. In our city, or a cell tower is being built in the backyard of a house several blocks from the residence.

Now, again, why mobile phones are not allowed to be in the aircraft in flight, because the channel reuse. The reason why mobile phones can be used by many, without interruption, even if on the same channel in the chain of reuse. Since mobile phones are designed to have limited influence, a mobile phone using the next cell or the tower would not be able to use another cell or the turn, even if the tower of this cell is only a few kilometers. This allows other mobile phones with the same frequency, the first phone to use the cell tower or other without interruption in the signal from the first mobile phone, even if the same frequency as the first mobile phone.

It was pointed out by the authorities if you have a cell phone in an airplane and the amount of the surface is within range of many ground or cell towers, the speed, the plane moves contortions at reception and transmission of signals of most pages or cell towers because of signal interference with other mobile users on the same frequency as the mobile phone. Indeed, the result will negatively affect the basic operation of mobile phones, channels reuse. This is the main reason most national regulatory agencies, they do not allow mobile phones on planes are used during the flight.

The second reason would be with regard to electromagnetic interference electronic equipment of the aircraft. It has also been recalled by the authorities of an aircraft in flight, even if they are still within reach of the basement cell sites or towers, transmission and reception of signals and a mobile phone low, because the travel speed. And the phone is automatically more power to send and receive signals from the cell sites or towers, which have the possibility of strengthening the operation of electromagnetic devices of the aircraft. So for the safety of all, why not let our mobile phones during flight?
