7.3. GSM/WCDMA Antenna – Installation Guidelines
 Install the antenna in a place covered by the
GSM/WCDMA signal.
 The Antenna must be installed to provide a separation
distance of at least 20 cm from all persons and must
not be co-located or operating in conjunction with any
other antenna or transmitter;
 Antenna shall not be installed inside metal cases;
 Antenna shall be installed also according Antenna
manufacturer instructions.
 FCC Section 15.203 describes that the use of a
standard antenna jack or electrical connector is
prohibited.
Do NOT use this type of connector on the host system
and the host system should have one of special ones.
The host system designers should keep in mind this
information before they start their actual design.
Below descriptions will make it clearer.
According to the FCC requirement, SMA type is
prohibited because it is one of standard types but
the system designer can adopt RP-SMA type which is
considered a special type.
RP-SMA represents “Reversed Polarized SMA”.
