In the present day world, Mobiles have been playing a major role in better communication between one person and another. Air passengers are required by the law to switch off their mobile phones on board any flight. In this regard it is very important to maintain the consistency of communication even as a user flies in an Airplane. As a result many techniques have been introduced to meet the above requirements.
Sky Mobile is one such technique which provides support for both the user and the service provider for the communication in an easier and efficient way. This paper is an application of low frequency (LF) i.e. BLUE-TOOTH which is commonly used in short networks. We are placing a solution for mobile phones user’s to use their mobiles on Airplanes that will be safe and helpful for both customer and service provider i.e. traveling consumer and mobile companies. This solution enables the user to remain connected in flight; the switch over from the cellular network to the in-flight Bluetooth network does not require any user initiation or change of the mobile handset. Here we make use of Bluetooth Airplane Gateway (BTAG) to detect the mobile phones while boarding and Ground Switching Center (GSH) to record the incoming calls and outgoing calls. Hence the user uses his handset as usual and not affecting the aircraft signals and the communication continues naturally.
Air passengers are required by the law to switch off their mobile phones on board any flight. This requirement has been imposed due to the two reasons. o First, signals emitted by the mobile phones interfere with the Air Traffic Control (ATC) signals, undermining the safety of the flight. o Second, a mobile at such an altitude connects to multiple base stations simultaneously, clogging the resources of the ground network. Sky mobile is the novel solution based on the integration of the diverse communication links: Bluetooth, cellular network (GSM/1S-95), PSTN and Air to ground connections. This solution enables the user to remain connected in flight; the switch over from the cellular network to the in-flight Bluetooth network does not require any user initiation or change of the mobile handset. Bluetooth, due to its power and short range and frequency hopping present negligible interference to ATC signals. When the passenger enters the plane, call forwarding is set up from the cellular networks to Grounds Switching Center and hazardous GSM emissions of the mobile phones are automatically switch off. All voice (or data) is received at GSC and transferred to an air ground to link to the Bluetooth airplane gateway (BTAG)in the plane. Data received at BTAG is finally transmitted over an in flight Bluetooth network to the passenger here a Bluetooth enabled GSM phone is implemented on a laptop using a GSM modem and a Bluetooth kit &the ground switching center using a phone modem for connecting to the PSTN the automatic set up of various communication hops, call routing & transmission of voice over these link has been demonstrated, the system provides a unique & useful service is & perceived to be highly marketable.
II. SYSTEM OVERVIEW
o The switch over from cellular network to the Bluetooth network is automatic, not requiring any user initiation. o The user phone number stays the same & he may receive calls on his usual mobile. o No change of handset is required while boarding a flight. Here the Bluetooth Airplane Gateway (BTAG) detects mobile phones as soon as it enters the airplane. The Bluetooth airplane gateway (BTAG) instruct the mobile phone...
