Transmit Data Rate
The data rate in the transmit direction, expressed in Mbps and presented as: max,
mean, min, and latest in an histogram format. The max, min and latest are true
instantaneous measurements; the mean is the mean of a set of one second means.
Expected data rates can be found in Data rate calculations on
page 4-99.
Receive Data Rate
The data rate in the receive direction, expressed in Mbps and presented as: max,
mean, min, and latest in an histogram format. The max, min and latest are true
instantaneous measurements; the mean is the mean of a set of one second means.
Expected data rates can be found in Data rate calculations on
page 4-99.
Link Capacity
The maximum aggregate data rate capacity available for user traffic, assuming the
units have been connected using Gigabit Ethernet. The link capacity is variable and
depends of the prevailing wireless conditions as well as the distance (range) between
the two wireless units.
Transmit Modulation Mode
The modulation mode currently being used on the transmit channel. A list of all the
modulation modes can be found in Data rate calculations on page 4-99, whe
re data
rate calculations plots are given for each available modulation mode.
Receive Modulation Mode
The modulation mode currently being used on the receive channel. A list of all the
modulation modes can be found in Data rate calculations on page 4-99, whe
re data
rate calculations plots are given for each available modulation mode.
Link Symmetry
A ratio that expresses the division between transmit and receive time in the TDD
frame. The first number in the ratio represents the time allowed for the transmit
direction and the second number represents the time allowed for the receive direction.
NOTE
Link Symmetry is configured at the master ODU only. The appropriate
matching Link Symmetry is set at the slave ODU automatically. For example,
if Link Symmetry is configured as “2 to 1” at the master ODU, then the slave
ODU will be set automatically as “1 to 2”. In this example, the master-slave
direction has double the capacity of the slave-master direction.
