User:M86/Receiver sensitivity table

From WikiDevi.Wi-Cat.RU
Jump to navigation Jump to search

Much of this information may be inaccurate, depending on the source (and other factors). Take it with a grain of salt.

Theoretical receiver sensitivity (dBm):

  • 1M=-104.5
  • 2M=-101.5
  • 5.5M=-97
  • 11M=-94
  • 802.11g/802.11a:
  • 6M=-97 (1RX stream), -100 (2RX streams)
  • 9M=-96 (1RX), -99 (2RX)
  • 12M=-94, -97
  • 18M=-92, -95
  • 24M=-89, -92
  • 36M=-85, -88
  • 48M=-81, -84
  • 54M=-80, -83

Conditions:

  • frame length = 1000 octets
  • PER = 0.1
  • Noise Figure = 0 dB
  • Implementation margin: 0dB

Notes:

  • The difference in sensitivity between PER=0.08 (BER=1.05e-5) and PER=0.1 (BER=1.32e-5) is 0.11dB (not significant).
  • For practically achievable sensitivity, add 2-3 dB to the numbers above (1-2dB for front-end filter loss and 1-2dB for LNA noise figure)
  • The 802.11 acceptance test limits are 15 dB above the theoretical limits (see section 18.3.10.2 - Receiver minimum input sensitivity)
