Tab. 1.a
The band centred around 2.45 GHz (used in the easy way ARIA system)
is the only one that can be used all over the world, without needing to
apply for special licenses. In addition, the ISM band (Industrial, Scienti c
and Medical) exploits the full potential of the standard, that is, can use 16
transmission channels with a bit rate of 250 kbit/s.

The MESH layout, used in the easy way ARIA system, between coordinator
nodes (access points) and routers (repeaters) ensures a high tolerance to
faults, as if one router is damaged, the wireless signal still manages to  nd
the fastest route to reach the destination .
