14. Transmission range
The transmission range of the radio signals between outdoor sensor and weather station is up
to 30m under optimum conditions. This is also often designated as "free-field coverage".
However, this ideal arrangement (e.g. weather station and outdoor sensor on
a plain, even meadow without trees, houses etc.) never exists in practice.
Normally the weather station is installed in the house and the outdoor sensor is mounted, e.g.
outdoor next to the window.
The range can sometimes be considerably reduced due to:
• walls, reinforced concrete ceilings
• coated/metallised insulated glass
• vehicles
• trees, brushes, earth, rocks
• the proximity to metallic & conductive objects (e.g. heating elements)
• proximity to human body
• Broadband interferences, e.g. in residential areas (DECT telephones, mobiles, radio-
controlled headphones, radio-controlled speakers, other radio-controlled weather stations,
babyphones etc.)
• Proximity to electric motors, transformers, power supply units, computers
• proximity to badly shielded or openly operated computers or other electric devices
Since local conditions vary from site to site, a definite range cannot be
guaranteed.
However, trouble-free operation is usually possible in a detached house. When
the weather station doesn’t receive any data from the outdoor sensor (despite
new batteries), reduce the distance between outdoor sensor and weather
station, change the installation site.
