14 Data Rate Calculations
To aid the calculation of data rate throughput (end to end ethernet throughput assuming 1500
octet ethernet frames), 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 (High priority traffic), although
there is a small difference between the two modes' rates because there is fragmentation in
TDM (for low priority traffic) which causes the throughput to be reduced buy approximately
1% compared to the IP mode.
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) There are more than this
Using these parameters the Receive and Transmit data rates can be looked up using the
plots Figure 110 through Figure 122.
Need a way of adding data for different bandwidths and TDD structures
