... and getting even more complex
Why mesh? Increased mesh coverage to go around obstacles Extended range with extra hops The topology can withstand the high traffic Alternative routes to get the transfer done A broken node will not destruct the transmission Expansion or modification can be done without disrupting other nodes
The reasons not to use mesh High chances of redundancy and latency Increased delay caused by multiple hops Set-up and maintenance can be difficult This type of topology requires a lot of devices hence it can be very expensive
Redundancy, latency and delay Robust routing algorithm PATENTED, directed flooding reliably working mesh network with 239 routers Fast Response Command PATENTED, the fastest wireless mesh network data collection worldwide, 2bits from 240 nodes in 26s, minimal network traffic and power consumption
