Be careful 1:
In 80MHz-800MHz, using a higher frequency formula
Be careful 2:
These guidelines do not apply in all cases. The material structure,
objects and people can absorb and reflect electromagnetic waves, thus affecting
the electromagnetic propagation
A. The radio base station (cellular and wireless) and ground mobile radio mobile phone
antenna, receiver, field FM and am radio as well as TV broadcast is unable to use pure
theory to accurately estimate.
In order to evaluate the electromagnetic environment of fixed RF transmitter generates,
should be taken into account. Electromagnetic field measurement method using field
measured if the equipment operating environment more than the required RF level, it is
necessary to observe the equipment to work properly. Once the abnormal situation, some
measures should be taken, such as re placing the machine direction or move it to the
environment.
B. In the 150kHz-80MHz frequency range, the field strength should be less than 1V/m.

Recommended distance between this system and portable / mobile RF
communication equipment
This system can be used to control the electromagnetic environment in RF interference.
In order to avoid the electromagnetic interference, customers or users should maintain
the minimum distance between the proposed system and portable / mobile RF
communication equipment. The following suggestions to keep the distance is calculated
according to the maximum output power of communication equipment.
