ALTA IoT cellular gateway

ALTA and ALTA XL IoT Gateways

Get Best-in-Class Cellular and Extended Connectivity

The ALTA® IoT Gateways and ALTA XL® IoT Gateways combine a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform (commercial only) with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA® Wireless Sensors.

The ALTA XL IoT Gateway also has a powerful wireless transceiver with up to 1 Watt transmission strength, an amplified receiver, and 4G LTE CAT-M1/NB2 cellular technology to backhaul ALTA® Wireless Sensor data. The ALTA and ALTA XL IoT gateways allow ALTA Wireless IoT Sensors to operate on the world’s leading cellular networks and stay connected to the Internet.

To meet the global demand for enterprise IoT deployment, the IoT Gateways communicate with the cloud-based iMonnitTM Monitoring Software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack (commercial only) allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.

Gateway Features

  • Unmatched wireless range:
    • The ALTA IoT Gateway communicates with battery-powered sensors up to one mile (line-of-sight) and 1,200 ft+ through 12+ walls (non-line-of-sight)
    • The ALTA XL IoT Gateway can receive and send data communications 2,000 ft+ through 18+ walls in commercial building environments.
  • Bank-level security: Encrypt-RF® (Diffie-Hellman 256-bit Key Exchange and AES-128 CBC)
  • Redundant power: AC main power with battery backup lasting up to 60 hours
  • Superior scalability: Supports up to 100 ALTA Wireless Sensors
  • Uninterrupted data collection: Onboard memory stores up to 32,000 sensor messages (Data stored during Internet outages is sent when connectivity is restored.)
  • Broad compatibility: LTE CAT-M1/NB2 for global use in bands: 1, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26, 27, 28, 66, 71, 85
  • Future-proof software: Firmware over-the-air (FOTA) upgrades included
  • Location Awareness: Comes with GPS data tracking capability and is available as an add-on service via an API.
