6. Baseband R503

› Generic platform for CPRI rearrangement
– Multiplexing / de-multiplexing
– Media conversion electrical <-> optical
› Flexible
–

–
–
FPGA and ARM-based
Upgradable
Manageable
Many possible locations in cabinet or at site
› CPRI Compression feature
– CPRI compression makes the CPRI link more efficient: more antenna
bandwidth can be carried over the CPRI link. The feature is supported on
Baseband 5216/5212. With the new generation of Radios, the feature is
directly supported between the RU and Baseband 52xx. With legacy
Radios, the feature can be supported with a Baseband R503 between the
RU and Baseband 52xx.
