Recommended Separation Distances

Recommended separation distances between portable and mobile RF communications equipment and the Masimo W1.

Rated maximum output power of transmitter [W]| Separation distance according to frequency of transmitter [m]
80 MHz to 2.7 GHz
0.01| 0.06
0.1| 0.19
1| 0.6
10| 1.9
100| 6
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: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
