Recommended separation distances
Recommended separation distances between portable and mobile RF communications
equipment and the Hill-Rom® 900 Accella™ bed and the Wi-Fi connectivity module.
The Hill-Rom® 900 Accella™ bed and the Wi-Fi connectivity module are designed for use in
an el
ectromagnetic environment in which interference due to radiated RF is monitored. The
user of the Hill-Rom® 900 Accella™ bed can contribute to the prevention of electromagnetic
in
terference by keeping the Hill-Rom® 900 Accella™ bed at the recommended distances
fr
om portable and mobile RF equipment (transmitters) as shown below, according to the
maximum power output of the communication equipment.

150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
0.01 0.12 0.12 0.24
0.1 0.37 0.37 0.74
1 1.12 1.12 2.33
10 3.67 3.67 7.37
100 11.6 11.6 23.3
For transmitters with a maximum power output that is not in the list above, the recommended
separation
distance in meters (m) can be calculated using the equation that applies to the
frequency of the transmitter, where P is the maximum output power of the transmitter in Watts
(W) assigned by the manufacturer of the transmitter.
At 80 MHz and 800 MHz, the separating distance in the upper frequency band applies.
These recommendations may not apply to certain situations. The propagation of electromagnetic waves is affected by
absorption and reflection due to structures, objects and persons.
