Sonim unveils portable HPUE hotspot for US emergency services
AT&T has announced the launch of the Sonim MegaConnect, a compact high-powered user equipment (HPUE) mobile hotspot designed to improve public safety connectivity across the United States.
The device, developed by Sonim Technologies, is part of the FirstNet MegaRange portfolio and offers six times the transmission power of standard Wi-Fi hotspots, according to AT&T.
The company said MegaConnect supports connectivity in areas with limited coverage, such as remote rural locations and dense urban buildings, by operating on Band 14 spectrum reserved for FirstNet.
The unit also works on AT&T’s 5G and LTE commercial bands and provides a portable Wi-Fi solution for mission-critical communications.
Sonim described MegaConnect as the smallest and most affordable HPUE currently available.
Enhanced mobility and speed for field operations
AT&T stated that the new hotspot transmits up to twice the upload speed of conventional devices.
The company said this improves the ability of first responders to transmit high-resolution footage, stream live video, and establish mobile command centres in the field.
MegaConnect is designed to be portable, weather-resistant, and simple to deploy.
Sonim said the device can be used during natural disasters and in hard-to-reach areas such as basements and underground car parks.
The device is available for $99.
Integrated cooling system enables device performance
The MegaConnect uses solid-state active cooling technology to maintain performance during operation.
The unit includes AirJet, a component from Frore Systems, which allows the hotspot to operate at full HPUE power in a compact form.
According to AT&T, heat management has previously been a barrier to mobile HPUE deployment.
The new cooling system enables continuous usage in environments with high communication demands.
This is designed to benefit emergency responders operating for extended periods without access to external cooling or charging.
Additional hardware expansion to extend range
Later in 2025, Sonim and Parsec will release an add-on dock for the MegaConnect.
According to AT&T, this new dock will include high-gain antennas and thermal regulation to support wider signal reach and system longevity.
The Parsec MegaReach Dock is expected to double the existing 6x transmission power to up to 12x.
This will allow the hotspot to cover larger areas and improve reception in difficult environments.
AT&T said the dock is intended to help emergency teams maintain signal quality during evolving or mobile operations.
Broader availability for commercial users
Although designed for public safety, the MegaConnect will also be accessible to commercial sectors through the AT&T network.
AT&T said industries including utilities, transportation, retail, and finance can use the device for infrastructure monitoring in remote locations.
The company stated that non-emergency users on AT&T’s commercial network can still benefit from the enhanced power of Band 14 when not prioritised for FirstNet use.
This secondary availability is designed to increase the device’s utility across critical infrastructure operators.
Public safety hotspot launched with 6x transmission power: Summary
AT&T has introduced the Sonim MegaConnect mobile hotspot in the United States.
The device is part of the FirstNet MegaRange HPUE portfolio.
It is designed to provide public safety teams with stronger connectivity in remote or enclosed areas.
MegaConnect offers 6x the transmission power of standard hotspots.
It operates on Band 14 and AT&T’s commercial 5G and LTE spectrum.
It uses a cooling system from Frore Systems to manage internal temperature.
The hotspot is compact and battery-operated.
It is currently priced at $99.
Later in 2025, a new dock from Parsec will extend its range further.
The MegaConnect will also be available to other sectors on the AT&T network.
