Tsunami MP.11a Antenna Installation Guide
Calculating Received Signal Level and Link Budget
Use the following formula to estimate the received signal level (RSL):
RSL (dBm) = Pout - L1+ G1 + G2 - L2 - Lp
where: |
|
Pout | is the transmitter output power (in dBm) |
L1 | is the total loss of all transmission elements between the antenna and the RF Unit on one |
| side of the link (in dB) |
G1 | is the gain of the antenna on one side of the link (in dB) |
G2 | is the gain of the antenna on the opposite side of the link (in dB) |
L2 | is the total loss of all transmission elements between the antenna and the RF Unit on the |
| opposite side of the link (in dB) |
Lp | is the Path loss, defined by:Lp (dB) = 96.6 + 20 log10F + 20 log10D |
| where: |
F is the Frequency of the radio system in GHz (5.8 in the case of this model)
D is the Distance of the path in miles
See the following figure for a visual representation of the elements of this equation.
