16. Range
The transmission range of the radio signals between mobile unit and the basis station or the outdoor unit
and the basis station is up to 200 m under optimum conditions.
However, the range values refer to the so-called „free field range". However, this ideal arran-
gement (e.g. mobile unit, basis station and outdoor unit on a plain, even meadow without trees,
houses, etc.) is, however, never possible in practice.
Usually, the outdoor unit is installed next to the entrance door and the mobile unit and basis
station are operated inside the building.
Due to the different influences on radio transmission, no specific range can be guaranteed, un-
fortunately.
Usually, however, operation in a family home is possible without any problems.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass, aluminium windows, etc.
• Trees, shrubbery, earth, rocks
• Proximity to metal & conductive objects (e.g. heaters, steel doors)
• Proximity to the human body
• Broadband interferences, e.g. in residential areas (router, WLAN devices, mobile phones, radio head-
phones, etc.)
• Proximity to electrical motors, transformers, mains adapters, screens
• Proximity to mains sockets, mains cables
• Proximity to badly shielded or openly operated computers or other electrical devices
