Cel-Fi reviews


Nextivity's second generation 3G repeater is an intelligent indoor coverage solution for 3G/HSPA+, designed to boost your mobile signal from outside and disburse within your home or office.

NOTE: This product will only operate on Spark's 850 network. It will not support the GSM or 4G band.

Cel-Fi differs greatly from the standard indoor repeater due to its ability to not interfere with the mobile network or other users. Often referred to as a Smart Repeater, the Cel-Fi has the ability to provide maximum coverage, be network friendly and can be easily installed by the end user.
