High Receiving Sensitivity
The static receiving sensitivity of the OB06 reaches up to -112dBm. The
high sensitivity guarantees the uplink channel performance of the OB06,
high sensitivity guarantees the uplink channel performance of the OB06,
and is one of the prerequisites for a wide coverage of the OB06.
Flexible Configuration
The OB06 supports 1~6 carriers per site in omni-directional or directional
coverage. It can support 1 ~ 3 sector configuration mode, which can be
coverage. It can support 1 ~ 3 sector configuration mode, which can be
selected by the user as required. Through the adjustment of front-end
gain (such as tower amplifier and low-noise amplifier), the loss in different
gain (such as tower amplifier and low-noise amplifier), the loss in different
length of feeder of the OB06 can be compensated to guarantee consistent
receiving system gain.
receiving system gain.
Easy O&M
The RF part of the OB06 can be controlled remotely through OMCR, to
change the transmitting power, transmitting/receiving frequency and more.
The alarm signals generated from the RF part are reported to OMCR, so
The alarm signals generated from the RF part are reported to OMCR, so
that the operators at the background can control the operation of the RF
part and know about the operation statuses.
part and know about the operation statuses.
Diversity Receiving
The OB06 provides the diversity receiving function, which is implemented
by two sets of independent receiving equipment at the same time,
including antenna, tower top amplifier (optional), feeder, divider and
including antenna, tower top amplifier (optional), feeder, divider and
receiver. The application of the diversity receiving function enhances the
anti-fading capability of the BTS receiver, enabling excellent receiving
performance of the BTS even in complex radio transmission environment.

Frequency Hopping
Frequency hopping is another important measure to enhance OB06
performance, which not only improves the anti-fading capability in the
downlink channels, but strengthens the communication security. The OB06
performance, which not only improves the anti-fading capability in the
downlink channels, but strengthens the communication security. The OB06
supports two working mode: hopping or no hopping. With hopping on, the
transceiver changes working frequencies according to a certain hopping

sequence, while with hopping off, the transceiver locks a specified working
frequency.
frequency.
Power Control
The OB06 can provide static power control, dynamic power control and idle
timeslot transmitting shutoff functions. The static power control range is
up to 12 dB, 2 dB per step. The static power control enables the user to
up to 12 dB, 2 dB per step. The static power control enables the user to
adjust the OB06 coverage. The dynamic power control range is up to 30
dB, 2 dB per step. The BSC can adjust the OB06 transmitting power
dB, 2 dB per step. The BSC can adjust the OB06 transmitting power
according to the distance between MS and OB06. In case of idle timeslot,
since there is no downlink signal, the BSC commands the OB06 to shut off
the transmitting power of that timeslot. These power control functions
since there is no downlink signal, the BSC commands the OB06 to shut off
the transmitting power of that timeslot. These power control functions
