IoT Edge Gateways: The Complete B2B Technical Guide
What an Edge Gateway Actually Does
An IoT edge gateway sits between field devices and the cloud: it aggregates MODBUS/RS485 sensors, translates to MQTT, runs local logic, and only ships summarized data upstream. That cuts bandwidth, latency, and cloud cost while keeping control local during outages.
Protocol & Compute Profile
A quad-core ARM Cortex-A53 on Linux/OpenWrt handles protocol bridging and light container workloads (Docker supported). I/O spans RS485/232, DI/DO, Ethernet, and CAN bus; LoRaWAN or Zigbee modules extend wireless reach.
Connectivity & Industrial Design
4G LTE Cat 4 / 5G Sub-6GHz with dual-SIM failover keeps the link up when wired drops. The enclosure is DIN-rail mount, IP30 metal, rated -40°C to +85°C for cabinet and outdoor edge duty.
OTA & Fleet Management
Secure OTA firmware update is table-stakes for deployed fleets; SDK/API access lets your team bake device logic without forking the firmware.
Frequently Asked Questions
Which protocols should the gateway support?
At minimum MQTT and MODBUS (RTU/TCP); CAN bus and RS485/232 cover industrial sensors; LoRaWAN/Zigbee extend wireless device reach.
Can it run my own logic at the edge?
Yes. Docker containerization on a quad-core Cortex-A53 lets you deploy local processing without forking the base firmware.
What keeps connectivity up if wired fails?
4G LTE Cat 4 / 5G Sub-6GHz with dual-SIM failover automatically switches carriers when the primary link drops.
Is the hardware rated for industrial environments?
DIN-rail mount, IP30 metal enclosure, -40°C to +85°C operating range — suitable for cabinets and harsh edge sites.
