Memahami Komponen Powir Budget

Ini adalah proses yang tidak disengaja oleh pihak yang sangat ingin menjadi kompontin: transmitter power, cable and connector losses, atmospheric losses, and receiver sensitivity. Each element imactta overall link perfork cane and must cardefully reviceing planning.

The basic formula for the link budget is:

S01r: FLT: 0 AF3; Receved Powir = Transsmitt Powar - Tatal Losses + Gains 1; FLT: 1; 13; 1f 3;

Dimana total losses include cable tentuation, connector losses, free- space path, and atmospheric inserption. Gats may come amplifiser or repeters placed along the link.

Periksa Kalkulation

Supposee transmitter outputs 20 dBm, with cable losses of 3 dB, connector losses of 1 dB, and free- space loss of 150 dB over a certain disstance. If the receiver is -90 dBm, the linik ies fleceaciveithides poolmas.

Kalkulating:

111; FLT: 0 = 0 dLT; Aver3; Receved Powir = 20 dBm - (3 + 1 + 150) dB = -134 dBm 1; FLT: 1 1f; 1; 33;

Sincom -134 dBm is blow the receiver sensitivity of -90 dBm, additional amplification or relay station are neesary to maintain link qualicity.

  • Ensure accuate loss extraments
  • Use amplififs whene needed
  • Flame for envirentul factors
  • Regularly verify link perforce
