ALTA gateways — exact network interfaces and scale

Selection pointOfficial model data and interpretation
Ethernet versionsStandard ALTA and ALTA XL Ethernet gateways connect up to 100 sensors each (maker’s current lineup). Ethernet 4K versions support up to 4,000 registered sensors and 1,000 simultaneous communications.
Radio/coverageALTA Ethernet claimed range up to 1,200+ ft through 12+ walls; ALTA XL up to 2,000+ ft through 18+ walls. These are reference-condition claims, not guaranteed building survey results.
Cellular alternativeALTA IoT gateways use 4G LTE Cat-M1 / NB2 communications with model-dependent cellular and Ethernet provisions; regional frequency/carrier compatibility and SIM requirements must be checked.
Software layeriMonnit provides alerts, dashboards and device configuration through supported gateways. The particular licensed cloud or on-premises tier controls features and retention; not universal.
Interface limitationsSerial Modbus gateway is a separate hardware family, with maker listing up to 50 sensors; do not assume a USB, Ethernet and cellular unit expose the same protocols or power interface.
Current page imageThe existing image shows a specific ALTA XL Ethernet Gateway 4K sample. It should not be interpreted as a photograph of standard Ethernet, cellular or USB variants.

Select site connection type, data retention, number of active wireless sensors and 868/915/433 MHz regional radio approval before selecting gateway SKU. Cloud alerts are not certified safety interlocks.
