8602 Radio Module
- 4 -
The signal must pass clear through
the structure to get out the other
side. –Good range
• Mounted on the inside of an exterior wall of a building. –Reduced range
• Mounted inside of a building with more than one wall to pass through before
signal reaches outdoors. -Further reduces range
• Mounting higher is usually better than lower. It would be preferable to mount
the controller above ground rather than in a basement.
• A larger building with more walls will effect range more than a small building
with only a few walls.
Type of Structure
The construction material of the building can have an effect on range and
performance. Wood and glass will reduce the signal. Any type of metal can
greatly reduce or block the signal.
• Pedestal mount with no structure.-Best range
• In a residential setting the signal can be expected to pass through one to
several wooden walls of a home and still generally reach to 500 feet.-Good
range
• A brick home could reduce that range slightly-Good range
• A steel reinforced concrete building.-Reduced range
• A steel walled building- Further Reduced range or a blocked signal
• Performance in a small structure will usually be better than a large structure.
Local Terrain and Local Conditions
• Clear line of sight will give the best range.
• The presence of a hill or earthworks between the modules can reduce radio
range.
• Walking into a low area or valley can reduce range.
• The presence of other structures or obstacles in the radio signal path can
reduce range.
