ALTA gateways — exact network interfaces and scale
| Selection point | Official model data and interpretation |
|---|---|
| Ethernet versions | Standard 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/coverage | ALTA 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 alternative | ALTA 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 layer | iMonnit provides alerts, dashboards and device configuration through supported gateways. The particular licensed cloud or on-premises tier controls features and retention; not universal. |
| Interface limitations | Serial 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 image | The 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.
