Advanced Data Processing Units

The clarification note:

In the realm of IoT, there’s a notable overlap among various device categories, particularly when discussing edge computing, gateways, and IoT hubs/concentrators. 

Edge computing refers to local data processing at or near the source of data generation, a capability that some modern gateways also possess. Gateways primarily act as intermediaries between IoT devices and the broader network, often with some data processing functions, aligning them with edge computing principles. 

Meanwhile, IoT hubs and concentrators are more focused on aggregating and managing data flow and communication within IoT networks. Although these devices have distinct primary roles, advancements in technology have led to their functionalities increasingly intersecting, especially in the context of managing and processing data in IoT systems. 

Edge Computing Devices

edge computing device

Edge computing refers to data processing that is performed at or near the source of data generation, rather than relying solely on a centralized data-processing warehouse. This concept is critical in IoT for reducing latency and bandwidth use. Within this category, several types of devices operate. Some of these devices can be classified as edge computing devices due to their data processing capabilities at or near the source. The list of devices is: 

  • uCPE (Universal customer premises equipment);
  • industrial PCs;
  • edge servers;
  • micro data centers;
  • edge gateways; 
  • edge notes; 
  • programmable automation controllers;
  • smart routers and switchers. 



Gateways often serve as a bridge between IoT devices and the broader network. While they primarily aggregate and transmit data, many modern gateways also have built-in processing capabilities. This allows them to perform some level of edge computing, such as preliminary data analysis or filtering.

Connectivity devices

Network Modules

Enable communication between IoT devices and the central system using technologies like Wi-Fi, Bluetooth, and cellular networks. 

IoT Hubs and Concentrators


These are more about centralizing data from various IoT devices and managing communication between these devices and the cloud or other network infrastructure. They can have some processing power but are often more focused on data aggregation and transmission. Specifically in the context of networks like LoRaWAN, I use concentrators that aggregate signals from multiple end-nodes. Other concentrator types are Sigfox, NB-IoT, and many many more. 

Analytics and Management Platforms

Cloud-Based IoT Platforms

iot cloud platforms

Offer powerful computing capabilities for data analysis, storage, and comprehensive supply chain management.

Dashboard and Visualization Tools

In the traditional approach at the supplier stage of the supply chain management, imagine a day in the life of a raw material coordinator, John. His daily routine is heavily reliant on manual processes and reactive strategies.

John begins his day by updating and reviewing inventory levels in the company’s software system. While the system itself is digital, the data entry is manual, often leading to delays and inaccuracies. 

Communication with manufacturers is predominantly via phone calls or emails. John often finds himself in situations where he can’t provide immediate updates on material availability or quality, as he’s waiting on information from the field or the warehouse.

Quality control is another area of constant challenge. John has to wait for reports from quality inspectors and has no real-time visibility into the conditions of the stored materials. Any issues discovered later in the supply chain can lead to significant disruptions and strained relationships with manufacturers.

The day ends with John feeling that he’s always a step behind, reacting to situations rather than proactively managing them.

IoT-Powered Approach
