RF Safety Requirements to 2.1091 for Mobile Transmitters
The unit under evaluation has an integral antenna. The ERP of this device was measured to be
32.4 dBm (1.738 W) at 848.8 MHz.

MPE calculations:
The occupational / controlled exposure limits are 2.83 mW/ cm2 at 848.8 MHz.

Using the power density equation:

Pt Gt
Pd =
4πr 2
Solving for distance r yields the following equation.

Pt Gt
r=
4πPd

Inserting the values and solving for r yields r = 7.0 cm.

The power density equation shows that the minimum separation distance to be 7.0 cm. Since the
EUT is considered to be a mobile unit, which by definition specifies that the antenna distance is
greater than 20 cm, the manual incorporates a caution statement that states that the unit should
only be used when a separation of 20 cm is maintained between the antenna and users. This
ensures compliance with the MPE requirements.
