3.4.4 Diversity Receiving

BTS3601C supports Diversity Receiving function, which is realized through two sets
of independent receiving devices (including antenna, feeder, MFEM and MTRM).
The two sets of receiving devices demodulate the received signals at the same time,
and then the baseband processing unit decodes the signals with diversity mergence
algorithm to obtain diversity gain.
Diversity Receiving enhances BTS receivers' capability to resist fade, so that the BTS
can achieve satisfactory receiving effect even in complicated radio transmission
conditions.
3.4.5 Cell Breath
BTS3601C can control the transmit power so as to adjust the effective coverage of
cells and balance the system load. This feature is especially important to CDMA
system.
The control range of transmit power provided by BTS3601C for cell breath is 24dB.
The transmit power is regulated at a step of 0.5dB.
3.5 Operation and Maintenance
BTS3601C provides convenient operation & maintenance functions. The functions
can be classified as loading management, configuration management, equipment
management, status management, tracing management and test management.
3.5.1 Loading Management
This function supports remote BTS software upgrading and remote configuration data
loading.
Loading management performs the software loading and loading of configuration
data.
Software loading involves downloading and activation of CPU software and FPGA
logic, while configuration data loading involves both downloading and uploading of
configuration data.
I. Software loading
When BTS is powered on and starts operation, its MBPB and MTRM will run the
existing software in the Flash Memory. When the user needs to upgrade the software,
