What is a wireless mesh network?

A wireless mesh network is a series of radio transmitting devices arranged in such a way that each transmitting device, or "node", can communicate with any other - rather than just back to a central receiver.

In self-configuring networks, like the Indigo network, nodes look around for their nearest neighbors and automatically establish links with them. This makes the network very reliable because if one node falls out, or is removed, the network searches for alternative routes to keep the communication path alive.

Low power

A great feature of mesh networks is that they can use a lot less power than traditional transmitters, therefore giving vastly extended battery life.

As a mesh, only enough power is required to reach the nearest node - instead of transmitting all the way back to a central receiver. Also, Indigo nodes spend most of the time "asleep" and wake only to transmit packets of data. This enables our batteries to last a year between recharging.

Indigo's networks are designed for transmitting any kind of environmental data. If it can be measured with a sensor, then it can be connected to an Indigo node and beamed back to the data collection point.


Of course, being a mesh network, nodes can receive as well as transmit. Therefore, Indigo networks are ideal for controlling as well as sensing. Instead of just monitoring the environment you can also control it. Typical applications include:

  • irrigation control
  • frost protection
  • remote starting of machinery
  • plant condition monitoring
