using two or more sectors, i.e. sector diversity

Introduced: January 2017

Full Title

Full titles differ between systems:

IPC:

Radio transmission systems, i.e. using radiation field > Diversity systems; Multi-antenna systems, i.e. transmission or reception using multiple antennas > using two or more spaced independent antennas > using two or more sectors, i.e. sector diversity

CPC:

Radio transmission systems, i.e. using radiation field (H04B10/00, H04B15/00 take precedence) > Diversity systems; Multi-antenna system, i.e. transmission or reception using multiple antennas (RAKE receivers H04B1/7115) > using two or more spaced independent antennas > using two or more sectors, i.e. sector diversity

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
