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
VOIP Performance Test Results
Spectralink (Polycom) underscore the superiority
of MeshDynamics MD4000 products for VOIP over wireless
mesh solutions. MeshDynamics demonstrated 12 VOIP
clients on 802.11g - a record. Polycom
Extensive testing has also been undertaken
in Underground coal mines
were VOIP phones are operating deep inside the mine
sometimes 40+ hops from the wired connection. The phones are mobile while active. [Press
With our patented
Persistent Mesh Technology
(P3M), VOIP phones function even
when the SIP gateway is not reachable: the mesh nodes act as a
temporary proxy SIP server till nodes rejoin the main mesh. Press
Bulking VoIP over Wi-Fi:
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.
Patented VOIP concatenation engine
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
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. [Details]
