Mesh Networks in Mining - Leaky Feeder Replacement
We have demonstrated clear real time VOIP multicast (push to talk) communications over a 50+ hop string of pearls wireless mesh chain in a coal mine. 150 mesh nodes were employed in the test, with multiple pathways each with nodes in a string of pearls chain. VOIP multicast traffic was successfully tested over 50 hops, end to end.
