6.3 Diversity
2-way receiver diversity is supported. Single receiver configuration is supported by both
receivers in case of failure of one of the receivers. Single transmit configuration is
supported in case of failure of one of the transmitters or antennas, allowing a transmit
mode configuration of Tx Diversity (SIMO).
6.4 RF Output Power
Transmit power maximum:
•
250 mW + 250mW
•
24 dBm per branch
Transmit power can be configured in different steps from the maximum down to the
transmit power defined for a LTE or WCDMA Local Area class:
•
250mW + 250mW
•
24 dBm (supported commisioning values: from 17 dBm to 24 dBm, step of 1 dB)
6.5 External RF Antennas
Pico indoor variants primarily utilize internal antennas. External antennas are also
supported but require additional hardware, as the Pico Indoor radio is not supplied with
external antennas or antenna mounting.
