Parameter Description
Channel
width
Channel width, shoud be the same on both Master and Slave units.
Frame
length
Frame period affects the following wireless link metrics:
The greater frame period the more payload will be transmitted in one
frame. Greater values increase latency.
The lower frame period the less payload will be transmitted in one frame.
Lower values decrease latency.
Please note that frame period value is strongly depends on interference
conditions. If larger frames will be dropped the larger payload is lost and system
performance is decreased significantly. If smaller frames will be dropped the
smaller payload is lost.
Guard
interval
Guard interval is intended for intersymbol interference elimination. One of the
intersymbol interference reasons is multipath propagation in which a wireless
signal from a transmitter reaches the receiver via multiple paths. Guard interval
affects payload size. So it should be increased only in case of significant
intersymbol interference.
Uplink
/Downlink
ratio
Allows to configure quotes for uplink and downlink directions. Available values
depend from:
Channel width.
Frame period.
