The SolidRF 4G MobileForce (first released as the Top Signal Cobra, and then renamed the Extreme Mobile 4G) - a 5-band booster with separate amplifiers for each band. According to SolidRF, other boosters generally have just 2 internal amplifiers covering a range of bands.
With improved filters, higher linearity and lower stand-by power consumption - specifications indicate that this booster might be a serious contender.
The booster will cover Verizon LTE, AT&T LTE, T-Mobile LTE, Sprint and most other 4G regional carriers, as well as 3G on all major networks.

Cellular boosters can be quite useful for boosting the signal to a smartphone to get a more solid phone call. But when it comes to enhancing cellular data performance, things get more complicated.
Because of a technology called MIMO (multiple in multiple out) that is essential to LTE and 5G data, often times the internal antennas on a smartphone or hotspot don't benefit from an amplified signal. Boosters also only cover a handful of the frequency bands the carries use for data.
But a booster can play a role in a mobile internet arsenal - as they excel during times when you are really far from a tower, or where upload speeds are important (such as video broadcasting).
