1W = 1000 mW Æ 10 x Log (1000) = 30 dBm
2W = 2000 mW Æ 10 x Log (2000) =33 dBm
C Max/ Min range (distance) WinLink 1000 sensitivity threshold in -60dB
range
(-30 dBm < RSS (sensitivity) <-90 dBm, in addition Propagation Delay is
also considered 3.3uS / 1 km (refer to Throughput vs Distance guideline
Example 2:
RSS = Tx(power) + Ant(Tx) + Ant(Rx) – loss
loss = 32.5 + 20 Log (D) + 20 Log (f);
D – Distance in km, f – Center Frequency
D Climate/Terrain Factor see Figure C-3 and Figure C-4
E Expected FM and RSS, refer to A and B
F Required Antenna Height, this is the required antenna height considering
the Fresnel Zone, see
Figure C-5 . Refer to WinLink 1000 site-survey
guideline.
 based on antenna beam
 Considering LOS (clear
Line of Site )
G Channel Bandwidth required with the available Radio Frame Pattern (RFP)
for collocated HSS systems.
