Working Principle

System operation is based on a self-configuring network architecture, implementing a communication protocol that guarantees the system operation, even when there are damage in the infrastructure .

The system continues operating facing:

  • Lack of electricity
  • Flood pipes
  • Interferences
  • Decoupling

The philosophy of our ad hoc network communication protocol makes the system more reliable the larger the installation is.

The wireless communication network is based on nodes that use radio frequency free band (ISM), so it is not necessary to pay for data transmission.


The radio modules form a communication network where each node is able to send or receive information at any point. The central node of the network, will receive all the readings and then it will send all this information to the central server.

The communication protocol provides real time monitoring,  when a network node produces a new piece of information  it is sent directly by RF to the central node. Each node has a radio range of hundreds of meters in an open space, so most of the time the system operates in this mode, updating all the system information in real time.

Generally, radio frequency systems tend to be more robust facing errors, because we know in advance that the problem is not in any of the wiring of the installation. Maintenance is reduced to verify the sender and receiver. This greatly reduces maintenance costs.

In contrast, radiofrequency systems have to overcome the handicap that the nodes farthest from the central node must be able to get enough signal strength. The communication protocol provides a solution to situation whereby the system is a self-configuring network for routing management.

An Intelligent Network Node

When any incidence takes place, for example a node is unable to communicate with the central node, the node starts a differente operation mode based on a smart routing protocol to achieve its goal: to get its meter reading or monitoring activity to the central node.

This is done as follows: the first thing is to launch a multicast signal so you can hear every node around. If there is any node ready to listen to this multicast signal means that the Node 1 could not send its reading directly to the central node, then Node 2 will act as a repeater, picking up a the information of Node 1 and sending the signal directly to the central node.

If the situation is adverse, then the above communication sequence is performed as many times as necessary until the information of the meter readings reaches the central node. The strength of the system lies in the intelligent routing capability built into each of the nodes. It is a network capable of responding to environmental adversities and taking smart decission to solve any communication problems.

In a conventional system (radio or cable based) without network intelligence, if the source node fails the central node will not receive the information. The network architecture solves these problems using secure data transmission and routing nodes.

An ad-hoc network system is more reliable the larger the installation is. This is a most valued feature by customers, and also for the maintainer and the controller.

Communications are confirmed end to end, this means that when we receive the OK control signal to activate a command we have complete certainty that this order has been executed.
