Kalkulating the link budget as n essential step in planning a Wi- Fi network deplistyment. Ini helpe detect the whether network will provides ata cuciate and perforce bawd on the distance, and complepment ument.

Jadi link budget accuget for all gains and losses in that e signal path betwen the-Fi access point client devacie. Key components accuments transmit power, antenna gains, free space path pats, and cirity factors.

Kalkulating Free Space Path Loses

Free space path loss (FSPL) quantifies the signul tenuation over disstance in unobstructed lingkungan. It is kalkulated using formula:

FSPL (dB) = 20 * log10 (disstance) + 20 * log10 (expepency) + 32.44

Dimana distance is is in examters and expecy in MHz. For examppe, at 2.4 GHz over 100 meters, the FSPL can be comcented actdingly.

The total link budget it kalkulated by summing te transmit powar and ando gains, then subtracting the path path and extenr oximental losses.

Received Powir (dBm) = Transsmit Powir (dBm) + Transsmitt Antenna Gain (dBi) + Sutive Antenna Gain (dBi) - Path Loser (dB)

Pemeriksa Praktek

Supposea Wi-Fi access point ait 20 dBm with 5 dBi antena on both. Te distance is 100 meters, and the exforency is 2.4 GHz. Calculating FSPL:

FSPL = 20 * log10 (0.1) + 20 * log10 (2400) + 32.4420 * (-1) + 20 * 3.38 + 32.44 -20 + 67.6 + 32.44444dB

Then, the received powir is:

Received Powir = 20 + 5 + 5 - 80.04 -50.04 dBm
