Datasheet. Release 1.9

Remote monitoring of critical infrastructure with edge computing

Overview
========

Pervasive computing systems are capable of collecting, processing and communicating data, they can adapt to the data's context and activity. That means, in essence, a network that can understand its surroundings and improve the human experience and quality of life.

CTHINGS.CO® Edge IoT Gateway (M) connects whatever data customer needs to process directly at the edge, reducing latency and relieving connectivity networks, with full support of Orchestra Platform.

The gateway is based on Linux. It provides tremendous possibilities opening up the entire embedded applications ecosystem. It supports industry standard specifications like mission-critical operation in temperatures ranging between -40°C and 85°C.

The design provides the flexibility needed while still keeping it simple! Based on the concept of modularity, it may operate with many wireless technologies without PCB redesign requirements. As of now, support for major cellular and other radio connectivity standards like Bluetooth 5.x, LTE Cat. 4, Wirepas 2.4GHz Mesh, Wirepas 5G NR+, Wi-Fi 802.11 a/b/g/n/ac, etc. are assured that will open up tremendous possibilities.

To ease deployment of use cases and solutions, the Edge IoT Gateway (M) is designed alongside CTHINGS.CO® Orchestra, a state-of-the-art networking solution making provisioning and maintenance of private networks as simple as a few clicks. Additionally, we open the possibility for curated backend systems including open APIs for connecting external systems, as well as data visualisation capabilities through our interfaces and supported protocols.
