About Bluetooth Range
This product features a powerful Class 1 Bluetooth radio to provide the
maximum possible range. As with all wireless technologies, the connection
range can vary widely depending on many factors such as the brand and
placement of the host device, the type and size of physical obstacles and the
presence and activity level of competing radio transmissions.
In range testing of this product while connected to a variety of typical host
devices with Class 1 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 Socket Bluetooth CHS.
• 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.
