CPC: Systems for communication between relatively movable stations, e.g. for communication with lift (H04B3/54 takes precedence)
Full Title
Full titles differ between systems:
IPC:
Line transmission systems > Systems for communication between relatively movable stations, e.g. for communication with lift
CPC:
Line transmission systems (combined with near-field transmission systems H04B5/00) > Systems for communication between relatively movable stations, e.g. for communication with lift (H04B3/54 takes precedence)
No child classifications to compare. This is a leaf node in both IPC and CPC.
