North American IoT Cellular Gateways
ALTA and ALTA XL IoT Gateways
The IOT Plus IoT Gateways and IOT Plus XL IoT Gateways combine a 4G LTE CAT-M1 / NB-IoT (NB2) cellular engine with an Ethernet platform (Enterprise models only) and the IOT Plus wireless access point network to aggregate and securely transmit data from IOT Plus wireless sensors.
Award-Winning Gateway Architecture
A core component of the solution recognized with the 2024 IoT Product of the Year Award, the IOT Plus XL IoT Gateway features a high-power wireless transceiver with up to 1-watt transmission strength, an amplified receiver, and 4G LTE CAT-M1 / NB-IoT connectivity to reliably backhaul sensor data.
Both IOT Plus IoT Gateways and IOT Plus XL IoT Gateways enable wireless sensors to operate on the world’s leading cellular networks, ensuring continuous internet connectivity for global deployments.
Designed for Enterprise and Remote Deployments
To support large-scale and international IoT use cases, IOT Plus IoT Gateways communicate with the IOT Plus cloud-based monitoring platform via cellular transmission—making them ideal for remote locations or environments without fixed internet access.
An RJ-45 Ethernet port (Enterprise models only) provides:
Local device configuration
Diagnostics and troubleshooting
Network connectivity redundancy
The gateway also delivers real-time notifications via text message, email, or phone call when user-defined conditions are met or exceeded.

Frequently Deployed Together

Open/Close
Our wireless open/closed sensors provide information on the status of doors, windows, cabinets, etc. Know if a building or area is being accessed when it should not be, or if a door or window has been left open.

Motion Detection
Our wireless motion sensors use an infrared sensing technology to accurately detect movements made by people/animals within 16.4 ft (5 m) range.

CO2 Gas
The mems based wireless carbon dioxide sensor allows you to monitor the level of carbon dioxide (CO2) gas in the surrounding air. Monnit wireless CO2 sensors have a small footprint and low cost
