1.3 Evaluation Distance
Evaluation Distance
Evaluation distance 20cm as a distance between the equipment and the operator or user when it is used
normally. The distance used for the assessment had be specified by the manufacturer and be consistent with
the intended usage of the equipment.
Evaluation Region
Far field region, r > (2*D^2/λ) (m)
Radiating near-field region, (2*D^2/λ) ≥ r > (λ/4) (m)
Reactive near-field region, (λ/4) ≥ r (m)
largest linear dimension = D (m), evaluation distance = r (m), wavelength = λ(m)

1.4 Evaluation Method
Evaluation Method
Far field region, For calculating the field in the far-field region the free space formula:
E (V/m) = d
GP30 Power Density: Pd (W/m2) = 377
E2
E = Electric field (V/m) P = RF output power (W)
G = EUT Antenna numeric gain (numeric) d = Separation distance between radiator and human (m)
The formula can be changed to
Pd = 2
d377
GP30
Radiating near-field region evaluation method:
SAR evaluation
alternative are E-field, H-field measurements
alternative either the synthetic model or cylindrical wave model.
The cylindrical wave model allows direct calculation of the power flux density, S, using:
S =
rD
P180
S = Power flux density W/m2
P = Power in watts radiated (W)
D = Length of antenna (m)
r = Distance in meters from the antenna
The cylindrical wave model is valid for a range of distances where rc (the distance at which the Cylinder and
far-field wave models give the same result) lies in the radiating near-field, and where the distance is less
than rc. At distances greater than rc the far field model (refer to the far-field calculation information in the
previous section) is more appropriate. Rc (m) – DG/2*δ/360
Reactive near-field region evaluation method:
SAR evaluation
1.5 Basic Restrictions
Restrictions on exposure to time-varying electric, magnetic, and electromagnetic fields which are based
directly on established health effects and biological considerations are termed “basic restrictions”. Depending
upon the frequency of the field, the physical quantities used to specify these restrictions are specific
absorption rate (SAR), and power density.
1.6 Reference Levels
Levels of field strength and currents that can be compared with corresponding measured or calculated values.
The reference levels are derived from the basic restrictions using worst-case assumptions about exposure. If
the reference levels are met, then the basic restrictions will be complied with, but if the reference levels are
exceeded, it does not necessarily mean that the basic restrictions will not be met.
1.7 Compliance criteria
If the average power emitted by apparatus operating in the frequency range 10 MHz – 300 GHz is less than or
equal to 20 mW and the transmitting peak power is less than 20 W then the apparatus is deemed to comply
with the basic restrictions without testing. The evaluation of power is only valid if it is made with an uncertainty
of less than 30 %.
