Notes

MCS15 (130mbps?) = see 'my post'

  • Don't forget to turn off AirMax and use a 20 MHz channel width, or your campers won't be able to associate to the AP.

MCS stands for Modulation and Coding Scheme. The 802.11n standard defines a total of 77 MCS. Each MCS is a combination of a certain modulation (e.g., BPSK, QPSK, 64-QAM), coding rate (e.g., 1/2, 3/4), guard interval (800 or 400 ns), and number of spatial streams. Support for MCS 0-15 is mandatory for 802.11n APs and support for MCS 0-7 is mandatory for 802.11n clients.

Calculating Signal

Cable

  • Microcom...PRO - $189, CARRIER - $249
  • Streakwave...PRO - $145, CARRIER - $185
  • Amazon and eBay...Shireen DC 1021 (similar to PRO cable) - $155
  • Both PRO and CARRIER GRADE are rated for CAT 5E up 1 Gbps
    • PRO has only foil shielding
    • CARRIER has foil and wire mesh shielding, and a plastic anit- crosstalk divider.

My Post

Signal-to-Noise

Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.
