Abstract

With the introduction of smart phones such as PDAs, the phone becomes more than just a verbal conversational tool, it becomes a personal communications device. These smart phones initially just had cellular radio. As technology improves it is possible to add other radio technologies into them such as WLAN and Bluetooth. These new radio technologies now provide alternative paths over which voice, email, web browsing can take place. Typically these new breed of smart phones have their cellular radios on all the time as cellular coverage is ambiguous and their other radios turned off, only being turned on when the other radio technology (i.e., WLAN or Bluetooth) is known the be in the vicinity.

Currently within aircraft, you are not allowed to make cellular phone calls.  In some jurisdictions, you are not allowed to make a phone call even if the door is open while some planes you can make a call only when the plane is not on the runway or in the air.  Some aircraft are now deploying WLANs to allow individuals to connect to the Internet from their laptops and with phones that have cellular and WLAN radios it would be impossible to turn on the device as the cellular radio would be active.  Therefore the device, even though it has WLAN capabilities, could not be used in the plane.

The phone has the capability that each...
