Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05
© SAMSUNG Electronics Co., Ltd. 2-2
Support of Broadband Channel Bandwidth
The outdoor SPI-2210 supports wide bandwidth of 5/10 MHz per carrier and high-speed
and high capacity packet service.
Support of 3Carrier/3Sector
The outdoor SPI-2210 can support 3Carrier/3Sector by the basic cabinet.
Support of MIMO
The outdoor SPI-2210 basically supports MIMO of 2Tx/2Rx RF path. There are methods
of MIMO as follows;
 Downlink
 Space Time Coding (STC): method for raising reliability of link
 Spatial Multiplexing (SM): method for raising data transmission rate
 Uplink
Collaborative SM (CSM): Doubled frequency efficiency
Support of Frequency Reuse Pattern (FRP)
The outdoor SPI-2210 supports FRP N=1 that provides the service to 3-sector by using a
carrier and FRP N=3 that provides the service to 3-sector by using different carriers.
A service provider can efficiently operate its own frequency resources by using the FRP
function.
Support of 4-Branch Rx Diversity (Optional)
The outdoor SPI-2210 supports 4-branch Rx diversity providing four Rx paths to each
sector to raise the Rx performance. In the outdoor SPI-2210, Mobile WiMAX base station
RF Receiver (MRR), an Rx module, should be additionally mounted to support 4-branch
Rx diversity.
Support of Various Frequency Allocation
The outdoor SPI-2210 supports various frequency allocation methods such as contiguous
carrier, noncontiguous carrier, FRP N=1 or FRP N=3. The outdoor SPI-2210 can apply RF
combiner optionally to such frequency allocation methods.
Support of Beamforming (Option)
The outdoor SPI-2210 is designed as the structure to support beamforming later.
The outdoor SPI-2210 mitigates the interference efficiently by uplink and downlink
beamforming to raises the average capacity and expand the data coverage. Also the outdoor
SPI-2210 needs the process to calibrate the reciprocity between uplink channel and
downlink channel.
