The Calculated Frame Results display several items of interest:
Table 44
OFDM Calculated Frame Results attributes
Attribute
Meaning
Modulation
The type of radio modulation used in the calculation (OFDM
for PTP 450)
Total Frame Bits
The total number of bits used in the calculated frames
Data Slots (Down/Up) This field is based on the
Downlink Data
setting. For
example, a result within the typical range for a
Downlink
Data
setting of 75% is 61/21, meaning 61 data slots down and
21 data slots up.
Round Trip Air Delay
(MaxRange)
This is the roundtrip air delay in bit times for the
Max Range
value set in the calculator
Approximate distance
(MaxRange)
The Max Range value used for frame calculation
BHM Transmit End
In bit times, this is the frame position at which the BHM
ceases transmission.
BHM Receive Start
In bit times, this is the frame position at which the BHM is
ready to receive transmission from the BHS.
BHM Receive End
In bit times, this is the frame position at which the BHM
ceases to receive transmission from the BHS.
BHS Receive End
In bit times, this is the frame position at which the BHS
ceases to receive transmission from the BHM.
BHS Transmit Start
In bit times, this is the frame position at which the BHS
begins transmission.
