Conforming to RTT&E Safety aspects
In order to comply with Specific Absorption Rate (SAR) specified as part
the RTT&E directive, the installation must fulfil the following points:
Antenna must not be installed directly (<1 m) beside people and
other equipment.
Antenna must have a gain less than or equal to 1.4 dBi at 850 MHz
and 900 MHz and a gain less than or equal to 3 dBi at 1800 MHz
and 1900 MHz.
Positioning of antenna
When setting up the antenna, movable objects such as doors and windows
should be positioned in the same way as when the meter is to be read. For
example, if doors will be closed after the installation during operation, the
signal strength is only valid when the door is closed. Avoid places where
moving metal objects can be found (e.g. cars in a garage).
The effect of weather on signal strength
Humidity, rain and lightning can affect signal strength measurements as
well as the frequency band being used. Additional margin beyond the
minimum signal level is needed to ensure reliable operation.
