9 Mobile MESH (Multi-Point-to- Multi-Point) Network
A Mobile MESH network is a cluster of MCUs over a radio link. The cluster includes at
least 2 MCU units and can range up to 32 MCUs. Each MCU unit receives from, and
transmits to, all other members of the cluster within the reception range.
least 2 MCU units and can range up to 32 MCUs. Each MCU unit receives from, and
transmits to, all other members of the cluster within the reception range.
The system is synchronized using a GPS or 1PPS External source. The MCU has an
internal GPS receiver and an external connector for GPS antenna (passive or active).
internal GPS receiver and an external connector for GPS antenna (passive or active).
In the Mobile MESH network, the transmission bandwidth is pre-allocated to each
member of the cluster; this allocation is called a transmission vector and can be
configured using the MC-EMA. All MCUs in the cluster must have the same
configuration (Frequency, Profile and Transmission Vector) with only one difference,
unit ID number.

configuration (Frequency, Profile and Transmission Vector) with only one difference,
unit ID number.
An MCU can be a “listener” only, receiving the information from all other members of
the cluster without consuming any bandwidth by not transmitting. In such configuration
the “listener” unit cannot be monitored via other units (over the air), it cannot be seen
in the link monitor screen since it does not transmit at any time. This application can
be used when transmitting broadcast data to several units, when there is no need for
sending data to the other direction. It can also be used when a unit is needed as a
relay only unit.

After powering up the MCU, it waits for synchronization (1PPS). As soon as the MCU

NOTE – The MCU can be synchronized by an external 1PPS source. For further
