RBS 2964(FOR MU ONLY) / RBS 2216
GSM Macro, high density,12TRX, indoor base station. Highly integrated (fewer cables and connections) and
compact, footprint-0.24sq.mm. Stacking one above other gives impressive ratio -
100TRX/Sq.meter. Total cost of ownership (TCO) is reduced as every
parameter’s performance is improved. Higher output with lesser power consumption. Can work in higher ambient temperature, reduction in fans
and cooling agents inside the shelter, room etc. Supports for both capacity and coverage requirements.

Power recommendations
Power consumption
• Max. power consumption is <=5172w at 200-250VAC.
• Max power is consumed during the initial charging of batteries.
• All PSUs ( 3PSUS/cabinet) are recommended with 1500W each.
• PSU efficiency not <= 87%.
• Hence, (3x1500)/0.87~5172W.
