Running the Link Budget Calculator Chapter 20
RADWIN 2000 User Manual Release 2.6.40 20-9
5. Enter the radio details. Note that Rate is chosen from a drop-down list:
Figure 20-9: Rate selector
The Rate shown, defines the air-interface rate in Mbps. The system operates in TDD
mode and has the overhead of the air-interface protoco.l Thus, the Ethernet actual
throughput is provided by the Ethernet Rate.
The Fade margin is the minimum required for line-o- sight (LOS) conditions. For
degraded link conditions, a larger Fade margin should be used.
The EIRP is given in dBm and Watts.
6. If the required range between the two link sites is known, you may enter it directly.
Alternatively, you may enter the latitude and longitude of each site in the link, in
which case the distance between them will be calculated and displayed.
Note
For collocation with:
• RADWIN 2000 products, you may only use RFP B or E.
• WinLink 1000 products, you may only use RFP E.
Note
If you choose Adaptive Rate, then the Rate list is unavailable as is the
Climate factor list. Both of these quantities are calculated.
Note
For a given air-rate, Ethernet throughput will decrease with increasing range
due to propagation delay.
