KT successfully completes 5G field tests in Pyeongchang, Gangneung, and Seoul.
KT announced that it has successfully completed 5G field tests in major areas of Pyeongchang, Gangneung, and Seoul, following Gwanghwamun, in order to showcase successful 5G pilot services at the 2018 PyeongChang Winter Olympics. KT constructed a '5G test network' around Gwanghwamun Square in Seoul in December of last year and successfully achieved 'handover' to minimize mobile communication disconnection using a bus equipped with a 5G terminal in an urban area for the first time in Korea.

ESP32 Development Environment Selection and GPS Application Implementation
The ESP32 is a microcontroller that integrates Wi-Fi, Bluetooth, 12-bit ADC, capacitive touch, PWM, DAC, and UART in a single SoC. However, the abundance of features does not by itself solve the designer's problems. The real challenges lie in selecting the appropriate development environment, determining which pins can be used and which must be avoided, and converting raw data from modules into usable information. This document addresses ESP32 peripheral constraints (ADC2 and Wi-Fi coexistence limitation, UART1 occupancy, ADC non-linear regions), the trade-offs between Arduino IDE and ESP-IDF, and the process from connecting NEO-6M/NEO-M8N GPS modules to UART2, parsing NMEA sentences, and visualizing routes in Google Earth, all organized based on documented references.

MIPI CSI-2, DSI-2, C-PHY, D-PHY Test Solution Technical White Paper
The MIPI interface adopts a burst mode that transitions between low-power (LP) and high-speed (HS) states for low-power consumption, and in return, strict timing rules are imposed on state transitions. Additionally, the high-speed section operates as a packet-based protocol with headers, ECC, and CRC, so verification engineers must handle waveforms and protocols simultaneously. Traditional configurations combining general-purpose oscilloscopes and AWGs reveal limitations in setup complexity, measurement uncertainty, and lack of reproducibility when faced with these requirements. This white paper, based on webinar materials, organizes the structure of this problem and describes how the SV5C-DPTXCPTX generator for receiver testing and SV5C-DPRXCPRX analyzer for transmitter testing integrate state transition testing, stressed eye testing, and protocol analysis into a single bench, along with their application boundaries.
