Patent ID: 7227444

Claim:
A radio frequency remote control device to request access to an area comprising: a radio frequency transmitter that is compatible for use with a plurality of different transmission frequencies and modulation types; an external communications interface; programmable logic having: a remote control signaling output operably coupled to the radio frequency transmitter; and a signaling input that is operably coupled to the external communications interface and wherein the signaling input comprises: a pre-existing application programming selection command signaling input; and an application programming signaling input; wherein the programmable logic is operated such that: when the signaling input comprises the pre-existing application programming selection command signaling input, command selection of at least part of at least one particular pre-existing application program from amongst a plurality of pre-existing application program candidates, wherein at least two of the plurality of pre-existing application program candidates have differing transmission frequencies and modulation types, as are currently available in the access requesting remote control device as a function of signaling as is received at the signaling input to control provision of corresponding remote control signaling via the remote control signaling output; when the signaling input comprises the application programming signaling input, command use of at least part of an application program as is downloaded thereat, which application program specifies a particular transmission frequency and modulation type from amongst the plurality of different transmission frequencies and modulation types with which the radio frequency transmitter is compatible to control provision of corresponding remote control signaling via the remote control signaling output; wherein access to the area is requested via the remote control signaling output.
