Wide Channel Bandwidth Support
The outdoor SPI-2331 supports 10 MHz bandwidth per carrier and has a large packet
service.
Support of Wideband Operation Frequency
The outdoor SPI-2331 can change the center frequency in each 72 MHz bandwidth with a
simple software change(no change in hardware required).
y
2,496~2,568 MHz
y
2,618~2,690 MHz
Support of 1Carrier/Omni
The outdoor SPI-2331 can support 1Carrier/Omni by the basic cabinet.
Support of MIMO
The outdoor SPI-2331 basically supports MIMO of 2Tx/2Rx RF path. There are two
methods of MIMO as follows;
y
Space Time Coding(STC): method for raising reliability of link
y
Spatial Multiplexing(SM): method for raising data transmission rate
Convenience Installation and Initialization
The outdoor SPI-2331 automatically receives its IP from the DHCP, and it is initialized
using software and configuration information saved in a non-volatile memory of the system
or an external server.
Schedule to Provide the System Feature
