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. Hard materials such as concrete
increase the range.
• Human bodies or containers of liquid positioned between the
host and the 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.
