HOW DOES CEL-FI WORK?
Cel-Fi is is a repeater system. It works by having two antennas, one externally mounted to a building or vehicle that communicates to the operator's network and one internal antenna with the building or vehicle that communicates with your mobile devices.
Cel-Fi works seamlessly with your existing 3G / 4G devices (Phone, Modem / Wifi Hotspot, iPad with Simcard, etc) by boosting the signal to the operator's network by up to 100dB. There is no need to connect to Cel-Fi in order for it to work. It can support up to 20 devices at once so everyone can remain connected.
