Shelter / equipment room can be

avoided by outdoor BTSinstallation. Modular, small andlight BTS minimizes also requiredcivil work cost

Antenna line civil work andcomponent cost can be minimizedby locating BTS close to theantennas (maximizes also cellcapacity)

In indoor installations additional airconditioning is not needed due to

low power consumption

Flexi power module (FPMA) consists of connector blocks and four slots for

AC/ DC sub-module (FPAA) or battery sub-module (FPBA).

FPMA can include:

. two FPAAs and two FPBAs

. three FPAAs and one FPBA

. one FPAA and three FPBAs

. one FPAA and three free slots for expansion.
