"Beyond Wi-Fi, to LTE and GPS" ESP32 Practical Communication Development Training Held
Published2025.11.20 10:33CEO Kim Bong-jo hosts a webinar on practical IoT communications based on ESP32.
As IoT devices expand beyond static indoor environments to include outdoor and mobile environments, ESP32-based communication development capabilities are emerging as a core skill among developers. Amid this trend, embedded education company Carelab announced that it will host a practical IoT communication webinar utilizing ESP32 and LTE/GPS modules on December 18th.The ESP32 is a System on Chip (SoC) with native integration of Wi-Fi and BLE. Its competitive price and high usability have led to its widespread adoption, from maker platforms to commercial IoT products. In particular, its combination with cellular modules like the SIM7600 and SIM800L is rapidly expanding its application in diverse fields, including battery-powered sensor nodes, location tracking devices, and mobile IoT devices.
ESP32: Evolving from a Maker Board to a Commercial IoT Device
The IoT market is experiencing a growing demand for data transmission and reception that cannot be met with simple Wi-Fi connectivity. This is because LTE-based data transmission and GPS-based location tracking are becoming essential for maintaining stable communications in outdoor environments. Accordingly, the ESP32 ecosystem, which can integrate and implement such functions on a low-power, low-cost MCU basis, is receiving attention again.
In the industry, the selection of HTTP/MQTT communication protocols, design of server/client structures, AT command-based module control, and setting up of development environments based on ESP-IDF and PlatformIO are considered the biggest barriers to entry in the early stages of development. This webinar aims to overcome these technical barriers to entry through hands-on practice.
The main curriculum of the webinar is comprised of the topic, 'Opening a real IoT communication with ESP32 - from setting up the development environment to utilizing SIM cards and GPS.'
The training content is as follows.
● GPS/cellular module integration
- Connecting modules such as SIM7600 and SIM800L
- AT command-based GPS coordinate collection
- Learning the flow of location data processing through server transmission
- ESP32 Server/Client Configuration
- HTTP vs MQTT Comparison
- Simple sensor data transmission practice
- Arduino IDE, ESP-IDF, PlatformIO, MicroPython Environment Features and Installation
- macOS-based setup and practical application tips provided
Demand for ESP-IDF and PlatformIO is on the rise, with growing interest from the industry.
Industry experts say that this year We estimate that inquiries about ESP-IDF-based product development are increasing. This is because the number of startups and manufacturers seeking to develop low-power IoT products in-house is increasing, leading to renewed interest in open-source, lightweight MCU platforms. Furthermore, PlatformIO, which allows for integrated management of various boards within the VS Code environment, is increasingly being utilized by professional developers.
Care Lab explained, “ESP32 is not just a hobby board, but has established itself as a platform that can support commercial devices as well,” and “In particular, as mobile IoT projects utilizing LTE and GPS communications are increasing, this webinar will be of practical help to developers considering a transition to practical work.”
For everyone from beginner to intermediate developers to working engineers
This training is for beginners in IoT and embedded development, those interested in implementing LTE and GPS-based location services, developers hoping to transition to an ESP-IDF and PlatformIO environment, and engineers who want to build their own server and communication structures.

SKT Receives International Standard for AI Data Center Interconnection Structure… Establishes Operating System Standards
SK Telecom's proposed AI data center interworking architecture has received final approval as an international standard at the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) conference. The core of this standard is the classification of AI data centers into three layers—service, management, and infrastructure—and the organization of signaling requirements between layers. As AI service proliferation increases the importance of interworking among various systems within data centers such as computation, power, cooling, storage, and security, this standard is significant in that it presents a common architecture for operations and service delivery. SK Telecom stated that it initiated the relevant standardization project in 2024 and achieved this approval following approximately two years of discussion.
