1.6 Why ZigBee
The use of ZigBee 3.0 allows Users to organize a convenient, safe and energy-efficient
environment. The key feature of the ZigBee Protocol is that devices (those which are
signal repeaters) do not need to directly contact the Control Gateway in order to
transmit a signal, since they can transmit it to another device within the network (See
Figure 4). So, in the case of failure of any node, the network will automatically be
restored by establishing new routes for data transfer. This increases the reliability and
flexibility of the system making it possible to install sensors at larger distance from
the Control Gateway even in the presence of obstacles (for example, reinforced
concrete walls).
It should also be noted that the ZigBee Protocol has several levels of security and uses
the AES-128 encryption algorithm (used by banking and government agencies), which
indicates a high degree of protection of the transmitted signal.

– Self-Recovery of the ZigBee Network
Thus, the advantages of using ZigBee 3.0 include the following:
 Data transmission over long distances and protection of transmitted data;
 Ultra-low power consumption and self-recovery of the network;
 Possibility of expanding the network to 65,000 devices and data exchange rate
of up to 250 kbps.
NOTE. Sensors and other battery-powered Perenio® devices do not have a
signal repeating function.
