Twierdzenie Shannona mówi, że maksimum danych jest prawdą, że to jest transmitowane przez sieć i że są one komunikowane bez błędów.

Teoretycy Shannona

Twierdzenie Shannona, że te dane maximum rate, or channel capacity (C), depends on the bandwidth (B) of te channel and thee signal- to-noise ratio (SNR). The formula is expressed as:

(1 + SNR) 1; FLT: 1 + 3; C = B * log2 (1 + SNR)

Appliing the Phatea in Wireless Networks

Te obliczenia te maksymalum data rate, identify they bandwidth of thee wireless channel and measure thee SNR. Plug these values into Shannon 's formula to find thee channel capacity.

For example, if a wireless channel has a bandwidth of 20 MHz and an SNR of 15 (about 11.8 dB), the maximum data rate is:

(1 + 15) (log2) (1 + 15) (1 + 15) (4, 0 = 80 Mbps) (1);

Factors Affecting Data Rate

Several factors influence the maximum data rate in wireless networks, including:

  • Bandwidth of the channel
  • Sygnał-to-noise ratio
  • Interference from teor devices
  • Quality of the transmissionon medium
  • Modulation techniques used d
