What is the difference between the H66 and the H68?

The H66 is the indoor model: plug-and-play with an emergency power-off alarm, up to 5 km range and an IP67 enclosure. The H68 is the outdoor model with up to 10 km range, IP68, and a design for long-term outdoor service.

Which frequency bands does it support?

CN470, EU868, IN865, RU864, US915 and AU915, matching regional LoRa band plans.

What happens if the power fails?

The gateway raises an emergency power-off alarm over its 4G backhaul, so the operations team knows immediately that the sensor network is offline.

How many sensors can one gateway serve?

A full-duplex industrial gateway can serve large sensor fleets; actual capacity depends on reporting interval, payload, and network conditions — share your device count and Hitelecom will size the network.
