A typical deployment for a remote monitoring solution will involve the following items from NCD.
Sensor
A sensor continuously measures the environment, typically temperature, and sends the readings to the gateway.
You will require one sensor for every chiller/freezer you wish to measure temperature in.

Frequency should be selected dependent on your region.
Gateway
A gateway is used to connect your sensor to QTRACA. A gateway can manage up to 10 sensors.
You will require one of these in your deployment.

Frequency should be selected dependent on your region.
Modem
If you have lots of interference within your environment, i.e. lots concrete walls, then you may wish to create a wireless mesh by adding modems into the deployment. These modems will pick up signals from sensors and help relay them to the gateway.

Frequency should be selected dependent on your region.
Extension Cables
In addition you may wish to place antennas in closer proximity to a gateway using an extension cable:
