Comparing Data Transfer Rate of Digital Transmission Lines Around Us

Posted under: at 02:45

The following is my compilation of various data transmission rate around us. I roughly converted values in M or Kbps to a more meaningful KB/s or MB/s, and then sorted them by transfer rate from slowest to fastest.

  • CSD: 9.6 kbps, roughly 1 KB/s
  • HSCSD 3+1: 43.2 Kbps downstream, roughly 4 KB/s
  • V.90 over telephone lines: 50 kbps downstream, roughly 5 KB/s
  • GPRS class 8: 57.6 Kbps downstream, roughly 5 KB/s
  • I2C (standard): 100 Kbps, roughly 10 KB/s
  • IrDA (typical SIR): 115800 bps, roughly 11 KB/s
  • RS-232 serial port: 115800 bps, roughly 11 KB/s
  • CDMA2000 1xRTT: 144Kbps, roughly 14 KB/s
