About Kilobits per Second (Kbps)

A data transfer rate equal to 1,000 bits per second (10³ bps) in the SI/networking convention, or 1,024 bps in the binary/storage convention (the SI convention dominates for transfer-rate measurements per IEEE 802 + ITU-T G.992 standards). Reference values: legacy dial-up modems V.32bis 14.4 Kbps; ISDN BRI single-channel 64 Kbps + dual-channel 128 Kbps; legacy GSM voice 9.6 Kbps (uncompressed); voice-over-IP G.711 64 Kbps + G.729 8 Kbps; SD-quality MP3 audio 96-128 Kbps; AAC audio 64-128 Kbps; FM-radio-quality streaming 64-96 Kbps. Mobile-broadband 2G/EDGE ~50-200 Kbps, 3G/UMTS ~384 Kbps - 2 Mbps. The kbps unit dominates audio-streaming codec specifications (Spotify 'Normal' 96 Kbps + 'High' 160 Kbps + 'Very High' 320 Kbps; Apple Music streaming 256 Kbps AAC + Lossless 16-bit/44.1 kHz ALAC ~1,411 Kbps; Tidal HiFi Plus FLAC ~1,411 Kbps). Common LoRaWAN long-range IoT data rates 0.3-27 Kbps.

About Bits per Second (bps)

The base SI unit of data transfer rate per IEC 80000-13:2008 (Quantities and units — Information science and technology). bps measures the number of binary digits (bits) transmitted per second across a communication channel. NOT to be confused with bytes per second (Bps with capital B = 8× bps). Reference values for legacy + modern data rates: original 1830s Morse-code telegraph ~5 bps; 1971 ARPANET 50 kbps backbone; 1991 dial-up modems V.32 14.4 kbps + V.34 28.8 kbps + V.90 56 kbps; 1995 ISDN BRI 144 kbps; 2000 ADSL 256-768 kbps downstream; 2010 cable DOCSIS 3.0 100-300 Mbps; 2020s Fiber GPON/XGS-PON 1-10 Gbps to home; modern Wi-Fi 6 (802.11ax) up to 9.6 Gbps; 5G mmWave peak ~10-20 Gbps; PCIe Gen 4 ×4 NVMe sequential reads ~7.5 GB/s = 60 Gbps. The smallest bps measurements appear in low-power IoT protocols (LoRaWAN ~250 bps - 50 kbps; Sigfox ~100 bps).
