XXIII. SUBSCRIBER IDENTITY MODULE (SIM)

This invention also implements wireless data communications from cellular

phone towers for connecting to the remote data center wherein these cellular towers

utilize high speed internet broad connections such as a 4G connection, or even a

wi-fi,or wi-max connection.

In consideration of this design the remote wireless black box design must be

have a provision to connect to a cellular network when the flight is in range of a

cellular network.

The best and cheapest way to do is with subscriber identity module (SIM) card.

A subscriber identity module or subscriber identification module (SIM) is an

integrated circuit that securely stores the international mobile subscriber identity

(IMSI) and the related key used to identify and authenticate subscribers on mobile

telephony devices (such as mobile phones and computers).

This same circuitry can be built in the quick access recorder or other equipment

to be transmitted over the wireless network to remote locations for redundancy and

flight data backup.

As with modern day communications, it is possible to use the SIM card to

connect to wireless internet services, such as 3G, 4G, and several other

technologies.

The GSM network is a common network known all over the world, and thus

this network could also be used to connect flight data recorder systems to remote

data ground locations in order to provide redundancy to the flight data.
