In the City
Better connectivity in buildings, building shadows, and underground locations

High Power User Equipment (HPUE) Technology

Gain FirstNet Coverage Beyond Range of Today’s Standard Equipment

The range for cellular LTE/FirstNet coverage is typically limited by uplink power

By design, downlink power from the cell site is much greater than the uplink power from the user.

Our patented HPUE technology boosts the coverage footprint of the network up to 6x that of standard equipment.

Our proprietary technology allows us to tap into the power of the network without damaging the network – this is why Nextivity HPUE equipment is in a class of its own and able to deliver connectivity well beyond the range of standard offerings.
