Figure 12. CDU-F for GSM 1800 in a configuration with twelve TRXs (6 dTRUs) in one sector.
CDU-F can be used to optimise the cell for high capacity, since the possible number of
TRXs per antenna is higher for this CDU compared to any other CDU-type.
The CDU-F 1800 MHz main characteristics are:
• CDU-F is designed to enable many TRXs per antenna, see table 12.
• One CDU-F has the same physical size as of one CDU-G.
• Base band frequency hopping is supported.
• Required channel separation is 400 kHz. If a channel separation on 800 kHz is used
~1.0 dB higher maximum RF output is achieved.
• IM3 limitations on frequency planning (CDU-F might require IM3 frequency planning
depending on the bandwidth used by the operator.)
• One, two and three sector configurations in one RBS 2206 cabinet are possible.
• Dual band (900 and 1800 MHz) configurations are supported using different CDU-F
(different frequencies).
