Obliczanie ing te e link budget for microvave links i s essential for ensuring releable communication over long distances. It involves assessingg thee total gain and loss in thee signal path to determinate if thee link will perfoct effectively undeid specific conditions.

Te link budget calculation consideras various factors, including transmited power, antenna gains, free space path loss, and additional losses. These consigents help estimate thee received signal exerth at thee receiver end.

Key Parameters in Calculation

Znaczenie parametrów w tym:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Transmitter Power (PT): Xi1; Xi1; FLT: 1 Xi3; Xi3; The power output of the transmitter.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Antenna Gains (GT andd GR): Xi1; FLT: 1 Xi3; Xi3; Gins of the transminting andd receiving antens.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Free Space Path Loss (FSPL): Xi1; Xi1; FLT: 1 Xi3; Xi3; Loss due te to signal spreading over distance.
  • Reg.

Kalkulating Free Space Path Loss

FSPL can by calculated using the formula:

FSPL (dB) = 20 * log10 (distance) + 20 * log10 (frequency) + 32,45

Te general formula for thee link budget is:

Received Power (PR) = PT + GT + GR - FSPL - losses

Jeśli odbiorca przekroczy limit czułości, to link i s considered viable.
