Integrated antennae
The following is a list of characteristics for integrated antennae:
-
Bandwidth: 1.88 to 1.93 Ghz
-
Impedance: 50 Ohms
-
TOS: 1.5:1
-
Gain: 3 dBi (maximum)
-
Polarization: vertical (axis of the antenna)
-
Width of the beam at 3 dB (vertical): 90º
-
Radiation diagram: omni-directional in the horizontal plane.
External antennae
According to the ETSI EN 301 406 standard, DECT antenna gain is limited to 12 dB +/-3dB. In
the case of external directional antennae, if a minimum safety distance of 50 cm is respected,
the SAR value is the same as the value obtained in the case of an integrated omni-directional
antenna (and therefore, lower than: 0.5 W/kg).
4.10.2.2.3 CONFORMANCE PERIMETER FOR EXPOSURE OF THE PUBLIC
-
Integrated omni-directional antennae: no limit for the conformance perimeter
-
External antenna (directional): the installation must allow for a safety perimeter respecting
a minimum distance of 50 cm.

RECOMMENDATIONS FOR INSTALLATION
4.10.2.3.1 Standard Topology.
The various building infrastructures are grouped into three types of geometric shape.
Coverage areas SQUARE:
Coverage areas RECTANGULAR
:
Coverage areas ROUND
The distances quoted below give an idea of typical range of a base station. It is clear that a
rectangular zone requires more base stations to provide full coverage.
4.10.2.3.2 Layout technique
For structures with a number of floors, different solutions can be envisaged as a function of:
-
the coverage obtained at each level.
-
the position of the Alcatel-Lucent 4070 IO/EO (higher or lower level).
