SPEEDLAN 9000 Mesh Protocol -- How It Works in Non-Line-of-Sight
Networks
Using SPEEDView the graphic above shows that every unit/router in the non-line-of-sight (NLOS)
network can be heard. These products provide the unique ability to "self-heal the network" as a
sector's topography or geography changes over time, and reach buildings blocked by obstructions
within line-of-sight.
What is happening in the graphic above?
You will notice negative numbers next to the units/routers, or referred to as nodes on the
network diagram. These numbers represent the signal strength for the nodes (or units/rout-
ers) in the diagram.
