The following are recommendations for transmission distance and can be used as a
reliable rule of thumb. These recommendations are generalised, and external factors may

The device carries the following approvals:
• ICASA (South Africa)
• CE (Europe)
• RCM (Australia)
Although -based networks are standalone, the network can be expanded
by including a Gateway Device. The gateway would link the network to the
outside world and allow for control and monitoring of the network.
A gateway device may, for example, be the Centurion Systems G-ULTRA GSM Ultra.
This device links the mesh network to the outside world and the user would
be able to link to the network using Centurion Systems' G-REMOTE mobile app.
The gateway has enabled connectivity with the individual WiZo units, allowing for them
