Attenuation – Distance from Exchange

  • Less than 1km = 24Mbit
  • 1.0km = 13.81dB = 23Mbit
  • 1.5km = 20.7dB = 21Mbit
  • 2.0km = 27.6dB = 18Mbit
  • 2.5km = 34.5dB = 13Mbit
  • 3.0km = 41.4dB = 8Mbit
  • 3.5km = 48.3dB = 6Mbit
  • 4.0km = 56dB = 4Mbit
  • 4.5km = 62.1dB = 3Mbit
  • 5.0km = 69dB = 2Mbit

SNR Margin

  • 6dB and below: Below Average
  • 7dB-11dB: Good
  • 11dB and above: Very Good
