3.TRANSMITTER CHARACTERISTICS

The requirements stated in this section are given as power levels at the
antenna connector of the equipment. If the equipment does not have a connector,
a reference antenna with 0 dBi gain is assumed .
Due to difficulty in measurement accuracy in radiated measurements, it is preferred
that systems with an integral antenna provide a temporary antenna conne ct or
during type approval.
If transmitting antennas of directional gain greater than 0 dBi are used, the
applicable paragraphs in ETSI 300 328 and FCC part 15 must be compensated
for.
The equipment is classified into three power classes.

A power control is required for power class 1 equipment. The powe r cont ro l is
used for limiting the transmitted power over 0 dBm. Power control capability
under 0 dBm is optional and could be used for optimizing the power consumption
and overall interference level. The power steps shall form a monotonic sequ en ce ,
with a maximum step size of 8 dB and a minimum step size of 2 dB.
A class 1 equipment with a maximum transmit power of +20 dBm must be able
to control its transmit power down to 4 dBm or less.
