    The block diagram in Figure 1 shows a simple indoor system design. Multiple units (cascaded or in parallel, including multi-band combinations) can be used in larger buildings to expand coverage by placing different EkoMini repeaters at strategic locations. The system design in Figure 2 shows a much more sophisticated dual-band (Cellular 800 MHz/PCS 1900 MHz) cascaded system for coverage up to about 150,000 square feet (14,000 sq.
