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
