4.3 Planning a radio cell
A floorplan must be available in order to plan a radio cell.
It is possible to plan multiple radio cells in such a way that they
overlap.
Prerequisite
The locations of the radio devices must be selected in accordance with country-specific
regulations governing automatic and non-automatic detectors.
The radio fire detection system is based on the following technological principles:
–
Mesh network
– Multihop
– Multichannel operation
The combination of these three technologies makes the radio system both unique and
extremely reliable.
Mesh network
A mesh network is a radio network linking two or more radio devices to an intermeshed
network.
Characteristics:
–
At least two paths between a radio device and the radio gateway
– Completely different routes; i.e., different radio links and different radio devices
– Radio devices connect to one another and configure themselves of their own accord. The
network continuously modifies itself during operation
