Features of BTS3900A Advanced Platform-Based Architecture

Based on the unified hardware platform, the BTS3900 supports three working modes: GSM

mode, GSM+UMTS dual mode, and UMTS mode through configuration of different

software.

In addition, the BTS3900 supports smooth evolution to the Long-Term Evolution (LTE).

Supports whole frequency band of PGSM 900MHz, high 45MHz frequency band and low

45MHz frequency band of DCS1800MHz, high 40MHz frequency band and low 40MHz

frequency band of 1900MHz.

High Capacity

When the BTS3900A works in GSM mode, a BBU3900 supports the maximum cell

configuration of S24/24/24, one cabinet supports the maximum cell configuration of

S12/12/12.

When the BTS3900 works in GSM+UMTS dual mode, a BBU3900 supports the maximum

cell configuration of GSM S4/4/4 + UMTS S2/2/2 or GSM S5/5/5 + UMTS S1/1/1.

When the BTS3900 works in UMTS mode, a BBU3900 supports 24 cells, 1,536 CEs in the

uplink, 1,536 CEs in the downlink, and the maximum configuration of 3 x 8.

Features of BTS3900A Transmission Sharing

Sharing the CPRI port. The CPRI data of the GSM and UMTS networks can be multiplexed

on the same optical cable, which reduces the quantity of CPRI ports.

Supports co-transmission between the GSM and the UMTS. Sharing transmission

resources between the Abis and the Iub interfaces.

Flexible Clock Synchronization Modes

Upper synchronization clock, extract clock from Abis/Iub interface.

Extract clock from GPS (Global Positioning System).

Synchronization with the IP clock, a highly cost-effective clock solution, which can be

obtained through software upgrade without additional hardware.

Clock phase lock, tracing, and memory functions and free-run synchronization mode. When

the clock operates in free-run mode, the system can keep operational for at least 90 days at

normal temperature.

Heater

The heater functions in the low-temperature environment to provide

suitable working temperature for the batteries in the power cabinet or

transmission cabinet. When the working temperature is lower than the

temperature specification for the battery, the battery capacity declines.

So the heater is installed in the battery cabinet to provide the optimal

working temperature for the batteries.

The technical specifications of the heater are as follows:A heater keeps the cabinet temperature higher than –10 . When the internal ℃

temperature of the cabinet is lower than 5 , the heater starts to work; when ℃

the internal temperature is higher than 15 , the heater stops working. ℃

The maximum power consumption of a 220 V heater is 300 W.

MRFU Module The MRFU is a multi-carrier RF filtering unit. One MRFU supports a maximum of

6 carriers in GSM mode, 4 carriers in UMTS mode, 6 carriers in GSM+UMTS

mode.

Functions: Implements the direct frequency conversion technique in the transmit channel, modulates

the baseband signals to GSM RF signals; then, sends the signals to the antenna for

transmission through the duplex filter after filtering, amplifying, and combining the RF

signals. The combining can be performed as required.

Receives RF signals from the antenna and performs down-conversion, amplification, analog-

to-digital conversion, digital down-conversion, matched filtering.

Provides power sharing. Improves the network coverage, reduces the interference and

power consumption and save the device cost.

Provides power control, reverse power detection.

Provides standing wave detection.

Configuration principle of MRFU Basic configuration principle:

One MRFU supports a maximum cell configuration of S6.

A single BTS3900 provides a maximum of 36 carriers with the maximum cell configuration

of S12/12/12. In addition, a site configured with the BTS3900s can support a maximum of

72 carriers with the maximum cell configuration of S24/24/24.

One MRFU does not serve two cells. Each cell with a single antenna can be configured with

a maximum of two MRFUs.

MRFU supports 1-way TX and 2-way RX.

Star, chain, and ring, are supported between the BBU and the MRFUs.

When star and chain topology is adopted between the BBU and MRFUs, the MRFU

supports 3 levels of cascading in a chain and thus the BBU supports a maximum of 18 (6 x

3) MRFUs.

Configuration principle Base on Limitation of MRFU

Assign frequency:

If the frequency interval of a cell is outside the range of 15MHz, 2 MRFUs can be considered

to be used and the range of frequency for each MRFU also should be within15MHz.

Generally, it is suggested that the number of carriers should be set to 2 MRFUs averagely if

2 MRFUs are used in a cell. For example: S8 should be configured as 4+4 when 2 MRFUs

are used. S7 should be configured as 3+4 when 2 MRFUs are used. If there’s limitation of

frequency band, S8 also can be configured as 3+5 or 2+6.

Frequency hopping:

Cell without frequency hopping. The cell can work normally when the range of frequency is

within 15MHz for each MRFU.

Cell with Baseband frequency hopping. The frequency range of 2 MRFUs must within 25MHz

when 2 MRFUs are used. And the range of frequency also must be within 15MHz for each

MRFU.

Cell with RF frequency hopping. The cell cannot adopt RF frequency hopping if the range of

frequency is out of 15MHz. Because the frequency range of 2 MRFUs must be within 15MHz

when 2 MRFUs are used.

Configuration principle Base on Limitation of MRFU

Output power:

The maximum output power of MRFU is 80W.

The output power for each cell must fulfil the requirement of network plan. When the

specification doesn’t fulfil the requirement, it can be improved by adding MRFUs.

The output power of all the cell must be the same because power sharing is mutually

exclusive with concentric cell. For example, S7 configured as 3+4 when 2 MRFUs

are used. The output power of MRFU configured as 3 carriers must be the same as

that of MRFU configured as 4 carriers.

Specifications of output power is Class 2, please refer to the next page.

Typical configuration of MRFU Single MRFU.

Double feeder, 1TX + 2RX.

When a dual-polarized antenna is configured,

one TX channel and two RX channels are

supported. The ANT_RXB and ANT_TX/RXA

ports receive the signals from the antenna to

achieve RX diversity.

Typical configuration of MRFU Two module interconnection.

Single feeder, 1TX + 2RX.

When the cell configuration is from S7 to S12,

two MRFUs need to be configured.

The ANT_TX/RXA port on each MRFU supports

the receiving and transmitting of signals. Two

MRFUs provide RX signals for each other through

the RF interconnection ports. Thus, the RX

diversity is implemented.
