Cellular Router vs. Cellular Modem (DTU): What is the difference and which do I need?
Cellular Routers can act as a gateway for multiple IP-based devices (e.g. CCTV cameras or PLCs) and provide wide network access using Ethernet (RJ45) and Wi-Fi. They support complex routing, VPNs (IPsec/OpenVPN) and high bandwidth capabilities.
Cellular Modems (DTU) are designed specifically to pass serial data (RS232/RS485) over cellular networks. They are lower bandwidth, lower power, and usually translate legacy serial protocols (like Modbus RTU) into cloud-friendly formats like MQTT or TCP sockets. If you only need to read serial meters, choose a DTU. If you need to view IP cameras or program a PLC remotely over Ethernet, choose a Router.
LoRa vs. Cellular 4G: When should I choose license-free radio over a SIM card?
Choose LoRa when you have a cluster of sensors within an 8km Line-of-Sight radius of a central facility, and you want to completely eliminate monthly data plan costs. LoRa operates on free ISM bands and is exceptionally low-power.
Choose 4G Cellular when your assets are scattered across the country (exceeding 8km), when there is no direct Line-of-Sight (mountains/dense cities blocking the signal), or when you need higher bandwidth than LoRa can provide.
Zigbee vs. LoRa: Which wireless technology is better for my factory floor?
Zigbee is superior for dense, obstacle-heavy indoor environments like factory floors. It utilizes a Mesh Network topology—meaning if a forklift blocks the signal between two nodes, the data automatically “hops” through a third node to reach its destination.
LoRa utilizes a Star topology (Point-to-Point/Point-to-Multipoint) which relies on raw signal penetration and long distance. It is better for wide, outdoor deployments like agriculture or pipeline monitoring, rather than weaving through dense indoor steel structures.
Is it secure to transmit Operational Technology (OT) SCADA data over wireless networks?
Yes, if you have the right architecture. For Cellular RoutersCellular DTUs Our devices use MQTT over SSL/TLS for communication. LoRa and Zigbee networks are inherently “air-gapped” from the public internet (acting as local area RF networks) and utilize built-in DSSS spread spectrum and network ID isolation to prevent local eavesdropping.
