14 Data Rate Calculations
To aid the calculation of data rate throughput, the following plots of throughput verses link range
have been produced for all the PTP 500 Series modulation modes, assuming the units are connected
using 100 Mbps Ethernet. Please note that only 15 MHz channel bandwidth has been considered
and the plots are the same for IP or TDM modes. Aggregate data rate capacity can be calculated
using four key system parameters:
• Receive modulation mode
• Transmit modulation mode
• Range Between the two wireless units
• Wireless link mode (IP or TDM) Using these parameters the Receive and Transmit data rates
can be looked up using the plots Figure 111 through Figure 125.
