Properties of wireless communication
` Frequency range 2.4 GHz ISM band
` Strong immunity to signals from other wireless services
` CFM (Coexistence Frequency Management) guarantees that
InduraNET p devices coexist without problem with other radio-based
systems.
– InduraNET p devices do not use non-overlapping WLAN channels.
– InduraNET p devices do not transmit until they have scanned their
frequency range (Listen before Talk).
– InduraNET p devices switch to free channels in order to avoid colli-
sions.
Properties of the antenna
` The antenna is designed to IP54. It can be installed on a flat surface
using one hole mounting.
` The SMA antenna cable is 2 m long and has an impedance level of
50 Ohm.
` The max. operating range depends heavily on surface reflection and
on the transmissivity of surrounding materials. Approximate guidelines
are:
– 10 m ... 100 m indoors
– 100 m ... 1000 m outdoors
` Two antenna types are available:
– For remote and base station:
PSS ANT 1 IDN is optimised for typical indoor applications.
– For base station only:
PSS ANT 2 IDN with two redundant antennas in one housing is op-
timised for high availability in difficult environmental conditions, e.g.
for mobile applications.
