Dual radio system continuously optimizes
mesh paths using 2.4GHz and 5.8GHz
radios for optimal bandwidth and reliability

Superior radio performance
Reliability in congested environments
Extending capacity and providing determinism
In congested environments network
performance can “fall of the cliff”!

In mining operations this can lead to
potential loss of productivity and capital
utilization

Wireless equipment and networks can
be designed extend capacity and
provide reliability even in congested
environments
