Product Overview
The RBS 6601 is a main remote RBS and a member of the RBS 6000 family.
The RBS 6601 consists of an indoor main unit and a number of RRUs, designed
to be located near the antenna, or AIR units. An optical fiber cable connects
each RRU or AIR unit to the main unit, as shown in Figure 1. Optical fiber
cables are available in standard lengths ranging from a few meters to several
hundred meters.
The support system for the RBS 6601 main unit is available in two variants:
variant 1 and variant 2. Information related to a specific variant is included
when necessary.
The fiber can also be extended or built using leased fiber. In this case, the
extension and delay of the fiber must be considered. The equivalent supported
distance between the main unit and the RRU or the AIR unit for WCDMA is
40 km (15 km with RRU22). For CDMA, LTE, and GSM, consult the market
representative.
