GENERAL OVERVIEW
Wireless Mesh Network
The Retriever & Pups wireless sensor network uses a mesh style
of communication, which allows any Pup within the network to
wirelessly route data from another Pup back to the Retriever.
The size of a network can vary by growing conditions,
topography, and user preference. The mesh network is
constrained to a maximum number of 16 Pups per network at a
distance of 2500 ft (about ½ mile or ¾ kilometer), or less
between Pups, with no more than four hops back to the Retriever
for the most remote Pups.
Pups have the ability to send their sensor data to the Retriever
within minutes of measurement. The data can be sent directly to
the Retriever, which logs the sensor data, or hopping via other
Pups within the mesh network. All Retriever and Pup units are
time synchronized. Because of this, the entire wireless network
can ‘go to sleep’ for periods of time to conserve battery life.
When the network ‘wakes up’, the Pups all communicate to the
Retriever and share any sensor data they have recorded while
the network was sleeping.
