Recommended Separation Distances between Portable
and Mobile RF Communications Equipment and Bigfoot
Unity
Bigfoot Unity is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the
user of Bigfoot Unity can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and Bigfoot Unity. The
Bigfoot Unity System was tested with several common electronic
products that could potentially cause interference, including a WiFi
router, a
Bluetooth
speaker, a Fitbit, a cordless phone, a baby monitor,
a laptop computer, and a microwave oven. At a separation of 1 meter
(about 3 feet), none of these products affected the operation of Bigfoot
Unity.
Recommended separation distances between transmitters and
Bigfoot Unity can be calculated using the table below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
