Signal-space views: BPSK (two antipodal points), QPSK/OQPSK (four points; OQPSK offsets Q to avoid 180^ jumps), and constant-envelope GMSK whose trajectory stays on a circle

Resource sharing: FDMA (frequency bands), TDMA (time slots), CDMA (whole band shared via codes) and OFDMA (subcarrier-time resource blocks)
