800MHz-2.5GHz
In the formula:
p--
according to the transmitter
manufacturer to provide the maximum
rated output power, in Watts (W);
d-
Is the recommended isolation
distance, in meters (m).
The field strength of a stationary RF
transmitter is determined by the
electromagnetic site survey and should
be lower than the compliance level in
each frequency range.
Interference may occur near devices
that mark the following symbols
注 1:在 80MHz 和 On the 800MHz frequency, the formula of higher frequency band is used.
Note 2: In these guidelines may not be suitable for all cases, electromagnetic transmission
is affected by the absorption and reflection of buildings, objects and the human body.
A fixed-type transmitters, such as base stations for wireless (cellular/cordless) telephones
and ground mobile radios, amateur radios, amplitude modulation and FM radio broadcasts,
and television broadcasts, are theoretically not accurately predictable in
their field
strength. In order to evaluate the electromagnetic environment of fixed RF transmitter, the
survey of electromagnetic site should be considered. If the measured field strength near
TEA Device is higher than the above applicable RF compliance level, you should observe
TEA Device to verify that it is functioning properly. If abnormal performance is observed,
additional measures may be necessary, such as resizing or position the device.
b in 150khz~80mhz the entire frequency range, the field strength should be lower than
3v/m.
