8 Air interface
Flexi Lite BTS has two transceivers: two 10 W transmitters and two -121 dBm (tunable
down to -107 dBm in steps) receivers. Flexi Lite BTS operates at:
•
Uplink: 1920 – 1980 MHz
•
Downlink: 2110 – 2170 MHz
Two-way receiver diversity is supported.
The RF output power can be set down to low power use (250 mW + 250 mW) with a
parameter, in ~1dB steps. BTS maximum output power (between 250 mW and 10 W)
can be set locally with a commissioning parameter or via NetAct. Note that maximum
output power limit must follow country-specific guidance if applicable.
Flexi Lite supports 3GPP Wide Area TS 25.104 Rel-9 standard.
8.1 Integrated antenna
Integrated antenna is an optional item and is included for both branches. Integrated
antenna is selected with a jumper cable connected from the antenna connectors to both
TX/RX connectors of the BTS.
Table 1 shows the specification of the antenna.
When the integrated antenna is not used, Flexi Lite BTS can be connected to external
antennas with RF cables. Receive diversity is supported with external antennas.
