RBS 6601 And RRURBS 6601 And RRU

RBS 6601 is very small indoor Unit and can be inserted into standard 19” rack already deployed at site.

Radio Remote Unit (RRU) -- As the name it self means that it remote unit which can be placed near antenna to minimize the feeder loss, which gives drastically reduced site power consumption. The baseband controlling the RRU can be deployed either in macro enclosures.
