As carriers phase out 3G networks, businesses need flexible solutions bridging old and new technologies. This dual-mode amplifier maintains GSM900/1800 compatibility for security alarms and POS systems while boosting 4G B1/B3/B7 bands for mobile broadband. A hospital using this system preserved legacy pager communications while enabling 4K medical imaging transfers. The auto-sensing technology allocates power dynamically - 80% to 4G during work hours, shifting to GSM for nightshift emergency alerts.
