Sensicast’s patented SensiNet^® technology is designed to deliver 100% reliable mesh network performance in collecting, routing, and delivering vital sensor data. SensiNet is an ultra-reliable mesh networking protocol that automatically manages the Sensicast mesh network.

SensiNet delivers an industry-leading reliability advantage through the use of patented automatic channel switching technology. SensiNet’s multi-channel approach makes the network highly resistant to the RF interference commonly found in industrial and commercial settings.

Self-forming, Self-healing, Bi-directional
A SensiNet network forms by simply turning on all of the devices in the network. Every device supports bi-directional communication, assuring that transmitted messages are acknowledged by the intended receiver (in the case of a transmitting Wireless Sensor, the intended receiver would be either a Mesh Router or a Gateway). If no acknowledgement is received, the message will be re-transmitted to a redundant, secondary receiver. If new Wireless Sensors or Mesh Routers are added to or removed from the network, SensiNet automatically reconfigures the network in real-time, permitting the node access if it has authorization.

Reliability: Frequency Hopping
SensiNet provides the foundation for the most reliable wireless sensor network available, regardless of the type of radio environment. Driving the reliability is implementation of frequency diversity radio modulation for both the 900MHz and 2.4Ghz solutions.

At 900MHz, SensiNet uses a slow Frequency-Hopping Spread Spectrum (FHSS) modulation technique to transmit and receive messages.

At 2.4GHz, SensiNet supports IEEE 802.15.4 radios (which are Direct Sequence Spread Spectrum radios) with frequency hopping modulation techniques applied as well. The result is a point-to-point radio communication that has proven 100% effective in power plants, steel mills and other harsh RF environments.

Network Topology: Hybrid-star
The SensiNet protocol is the most power-efficient and lowest latency protocol available. Wireless Sensors, also known as end points or star nodes, may be battery-operable and last for many years. They spend most of their time in a deep sleep mode, conserving energy and then awake to either receive messages or transmit sensing or status information. These devices can either communicate directly with the Gateway, or if added range or redundancy is required by the application, they can communicate with a routing device, called a Mesh Node. Mesh Nodes are typically line powered devices and remain in a receive or “listening” mode, reducing latency throughout the network. Multiple Mesh Nodes may be utilized in line to “multi-hop” messages through a SensiNet network.
