Guidance and Manufacturer’s Declaration – Guidance for Separation Distances
Recommended Separation Distances Between Portable and Mobile
RF Communications Equipment and the SPIDER2
The SPIDER2 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the SPIDER2 can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the SPIDER2 as
recommended below, according to the maximum output power of the communications equipment.
Rated Maximum Output Power of
Transmitter W
Separation Distance According to Frequency of Transmitter M
150 KHz to 80 MHz
d = 1.7 √ P
80 MHz to 800 MHz
d = 1.7 √ P
800 MHz to 2.5 GHz
d = 2.34 √ P
0.01 Not applicable 0.12 0.23
0.1 Not applicable 0.37 0.74
1 Not applicable 1.17 2.34
10 Not applicable 3.69 7.38
100 Not applicable 11.67 23.34
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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.
Guidance and Manufacturer’s Declaration – Electromagnetic Emissions
The SPIDER2 is intended for use in the electromagnetic environment specified below. The customer or the user of the SPIDER2 should ensure that it is used in such an
environment.
Emission Test Compliance Electromagnetic Environment – Guidance
RF emissions
CISPR 11
Group 1 The SPIDER2 uses RF energy only for its internal functions. Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.
