Max Links
(Master)
Maximum allowed number of connectedCPEs ( in the case of radio
connection ) . When this value is reached, other attempts to connect to
the base station will be rejected
Frame Size
(Master)
Set the time slot duration (in milliseconds)
Consists of transfer time, reception time and guard intervals
The range is from 2 to 10 ms in increments of 0.1 ms
The recommended values for links PtP at the balanced channel
depending on channel width: 2-2,5 ms for 40 MHz, 2-4 ms for 20
MHz, 3-5 ms for 10 MHz, >5 ms for 5 MHz
The recommended values for links PtMP depending on channel
width: 5 ms for 20 and 40 MHz
Auto
(Master)
This option works only for links "PtP" and allows to reduce the window
size and a delay at absence or a small amount of traffic. Automatically
selects the frame size
Turbo
(Master)
Increase the throughput in case of link degradation due to errors in the
radio. The sliding window of the ARQ algorithm are extended from
three to five frames, which increases its efficiency.
DL/ULratio (%)
(Master)
Set the DL percentage of the time slot
The range is from 20 to 80% in increments of 1%
The empty field enables the mode of flexible DL/UL ratio
adjustment depending on traffic load
Real accepted values depend on the used bandwidth, the frame size
and the used modulations. To determine the established value
acceptability it is necessary to control parameters (Tx Time Limit/Rx
Time Limit) in radio interface statistics. Any of these parameters shall
not be less than zero. In the PtMP system with a large number of
clients, the ratio of real throughput in this or other way does not match
the established DL/UL value. Uplink performance will always be less,
because of big overheads of the uplink traffic servicing. In case of a
large number of clients value more than 65% practically do not lead to
throughput increase in Downlink. Rated speed in Uplink and Downlink
(Rx Cap/Tx Cap) is reached only in case of sector full and balanced load
by all clients
MaxDistance (Km)
(Master)
Set the maximum operational distance (in kilometers)
Has an impact on guard intervals duration
The range is from 1 to 100 km in increments of 1 km
It allows the system to calculate signal propagation time to the furthest
subscriber and value of the guard interval between transmission and
receiving phases. It is recommended to set 3-5 km more than really
measured distance. In case of LOS condition violation or with a large
number of reflections larger value as 10-20 km can be required
