Do the current signal boosters support 5G or the Sprint Spark network?
The current signal boosters on the market support the five major cellular bands currently in use in North America. There are no signal boosters on the market that support the 2500 MHz band used for Sprint Spark or the 600 MHz band that some carriers plan to use for 5G data.
All new future technologies (X-LTE, 5G) deployed by the carriers that use one of the five major cellular bands: 700, 850, 1700, 1900, and 2100 MHz will be supported by the current signal boosters on the market. Technologies that are deployed on bands other than that will not be supported by any of the current signal boosters.
