device, the type and size of physical obstacles and the presence and activity
level of competing radio transmissions.
In range testing of the Bluetooth CRS while connected to a variety of typical
host devices with Class 2 radios, functional connection distances from 18 to
over 100 feet have been experienced depending on the environment. The
following conditions appear to reduce the Bluetooth connection range:
• The presence of soft, absorbent materials such as paper, fiberglass
insulation, foam material in office cubical walls, carpeting and, to a lesser
extent, even sheetrock and wood construction materials.
• Human bodies or containers of liquid positioned between the host and
the Bluetooth CRS.
• The presence and activity level of competing Bluetooth or 802.11 (Wi-Fi)
systems using the same 2.4 GHz frequency.
• Metal in a grid pattern, such as chain link fencing or chicken wire. This
type of material may block the Bluetooth (or Wi-Fi) signal completely.
