Modules
Integrated TRX, MCPA, Filter Unit and DC/RET/alarm/RF surge-protection blocks; approved SFP modules in four optical ports; optional replaceable fan unit
Functional role
PN KRC161960/1; Single-unit, single-sector triple-band FDD+TDD radio for 1800/2100/2600 MHz modernization
For PN KRC161960/1.
Architecture
Self-contained triple-band radio with integrated TRX, three MCPAs per RF port, Filter Unit and input/interface surge protection; four shared RF branches, four optical CPRI data ports and optional external fan
Subtype
4T4R common-port B1+B3+B41 FDD+TDD triple-band Radio 4466
Details
PN KRC161960/1; Ericsson announced the first live use of this triple-band FDD+TDD technology in one unit and up to 15% energy-consumption reduction versus the earlier radios it replaces
For PN KRC161960/1.
