2.3. Base Network - No Redundancy
Although two WiZo-Link devices are
required to form a basic network,
this does not constitute a mesh
network. Node A has direct line-
of-sight to Node B and Node B the
same for Node A; if there were
interruption, there is no alternative
path for the message to be
delivered.
WiZo-Link devices that do not have any I/O links confi gured add value to the
network as they function as repeaters. This helps strengthen the robustness of
the mesh network.
2.4. Designing the Network
When mastering the network, mastering onsite has the advantage of the master
selecting a channel that has low energy and minimal interference from other RF
devices or even an adjacent WiZo-Link network.
More than one WiZo Network can coexist on the same channel, provided they
are not in permit mode at the same time, which will interfere with federation.
When planning the network, a few essential elements must be considered before
physically installing each WiZo-Link device or node. Since the WiZo-Link is a wireless
device, physical installation is minimal, and this does allow for moving elements around.
However, sensible planning to begin with will ensure that the network is set up and
installed with minimal errors or issues.
2.4.1. Establishing the Network
When planning the WiZo-Link network, it is important to consider the paths that are
available for a message to travel from one point to another. It is possible to create a
network where there is a combination of full- and partial-redundancy. When travelling,
the message may have line-of-sight from source to destination node, or the message
may be routed via multiple nodes before it reaches its destination. The WiZo-Link
devices determine the best route to deliver the message, and good network planning
goes hand-in-hand with this process to ensure that the devices have enough available
paths to ensure that the message is delivered.
Redundancy is aff ected by the distance between nodes as well as the availability
of nodes. This can be impacted by obstructions, where although the devices
are close enough, or there are enough nodes on the network, the interference
prevents the signal from being transmitted or received.
