Besides the inherently high performance of MeshDynamics'
patented multi-radio backhaul technology, additional
specialized voice features minimize delay and jitter. These
features insure that voice is transported rapidly and
efficiently across the network, maximizing the number of
voice calls that may be supported while minimizing wasted
Managed Latency and Jitter:
Moving packets through a
Wi-Fi network uses significant overhead. Combine this with the relatively small packets for VoIP that must be sent at regular intervals, (e.g. every 20 ms) and the overall system becomes increasingly inefficient.
With more VOIP clients and as VOIP packets traverse multiple hops, latency and jitter performance degrades further in single backhaul radio products,
due to contention on the same backhaul channel.
MeshDynamics multi-radio multi-channel backhaul ensures deterministic latency and jitter by eliminating
both the effects of single radio backhauls and involuntary contention.

Figure 1 Explanation
: Since VOIP packets are small, inefficiencies related to transmitting small packets result in significant overhead. This adversely affects usable capacity. The Patent Pending MeshDynamics concatenation engine puts VOIP packets into a "container" packet. Containers are shipped periodically much like a bus arrives and leaves as a bus station at regular intervals. Bulk transport of VOIP packets is thus more efficient. Latency/jitter is also better managed than if the VOIP packets were individually transmitted - where they would be contending with each other.
