Routing or path finding of packets in data switching networks (routing or path finding in wireless networks H04W40/00)

Introduced: January 2022

Title

Titles differ between systems:

IPC: Routing or path finding of packets in data switching networks

CPC: Routing or path finding of packets in data switching networks (routing or path finding in wireless networks H04W40/00)

Full titles differ between systems:

IPC:

Routing or path finding of packets in data switching networks

CPC:

Routing or path finding of packets in data switching networks (routing or path finding in wireless networks H04W40/00)

Of 38 combined children, 21 exist in both systems.

17 codes are CPC-only extensions.

IPC defines codes here since 2022.
