8. Preparations for setup and installation
Select an appropriate installation location. The following points/criteria must be noted.
a) Wireless signal transmission range
The transmission range of the wireless signal between the outdoor sensor and the weather station under optimal
conditions is up to 150 m. This range specification is, however, the ‘free-field range’. This ideal arrangement (e.g.
weather station and outdoor sensor on a plain, even meadow without trees, houses etc.) never exists in practice. The
weather station is usually set up in the house, the outdoor sensor is installed on or in a carport, a garage or in the
garden. Different objects have a different impact on the range, therefore no specific range can be guaranteed. The
range should, however, be sufficient for use in a detached house. If the weather station does not receive any data
from the outdoor sensor (despite new batteries being inserted), reduce the distance between the weather station and
the outdoor sensor. The transmission range can be considerably reduced by:
• Walls and reinforced concrete ceilings
• Coated/vapour-deposited insulating glass panes, aluminium windows, etc.
• Vehicles
• Trees, bushes, soil and rocks
• Proximity to metal and conductive objects (e.g. radiators)
• Proximity to human bodies
• Broadband interference, e.g. in residential areas (DECT telephones, mobile phones, radio-controlled headphones,
radio-controlled speakers, other weather stations operating on the same frequency, baby monitoring systems, etc.)
