Max Tx Retries
Wave Wireless recommends that you use this parameter to increase the throughput of
your wireless network. This parameter tells a network node the maximum number of
times a unicast frame can be retransmitted before it is discarded. (A unicast frame is
one that is transmitted to a single node in a network.) This allows a network manager to
tune a network for its particular topology and expected traffic characteristics. The
network topology, RF environment, number of nodes, throughput requirements, latency
requirements, and type of applications are all factors in choosing an appropriate value
for this parameter.
This parameter can be tuned on a per unit basis in order to optimize network
performance. Click Default to get the default value of 7. You can select a value
between 0 and 8 from the Max Tx Retries drop-down list.
