Description
This is the generic class for modulated carrier wave communicationsnot elsewhere classifiable.
Some art areas excluded from this class are: Alternating orpulsating current telegraphy; Antennas; Broadcast or multiplex stereo;Condition responsive indicating systems with a radio coupling link;Directive carrier wave systems; Multiplex carrier wave communications;Paging via modulated carrier wave; Pulse or digital communicationswhich may be modulated onto a carrier wave; Reflected carrier wavesystems (e.g., radar); Selective (e.g., remote control); Telemarketing;Television; Facsimile.
