Microchip Announces "SW Redundancy" Timing Grandmaster
Published2021.03.19 14:45TimeProvider 4100 Grandmaster 2.2 Released
Reduce hardware costs by supporting software redundancy.
Microchip Technology Inc. today announced the availability of its TimeProvider® 4100 Grandmaster Version 2.2, an IEEE 1588 precision timing grandmaster that ensures always-on precision timing and synchronization. The new solution supports multi-band Global Navigation Satellite System (GNSS) receivers and offers enhanced security and a redundancy architecture for high resiliency.

Redundancy is a key requirement for network infrastructure providers to provide seamless, uninterrupted service. Previous infrastructure relied on expensive, modular architecture-based hardware redundancy to prevent service interruptions. The TimeProvider 4100 Grandmaster version 2.2 supports software redundancy, enabling flexible deployment and reducing hardware costs without sacrificing ports.
Additionally, to prevent time delays caused by space weather, solar activity, and other disturbances that can impact service, we've enhanced resilience by supporting new GNSS multi-band, multi-constellation receivers. Multi-band GNSS is crucial to ensuring accuracy levels of 40 ns for PRTC-B (Primary Reference Time Clock Class B) and 30 ns for ePRTC (Enhanced Primary Reference Time Clock).
Applicable to both new and existing systems, the TimeProvider 4100 Grandmaster version 2.2 supports RADIUS and TACACS+, as well as anti-jamming and anti-spoofing features. An optional super oven-controlled crystal oscillator (OCXO) with enhanced holdover capability is also available for use in the event of GNSS outages.
Additionally, it features hardware expansion modules for legacy fan-out or Ethernet fan-out supporting 10Gb Ethernet, and can be configured to operate as a gateway clock, high-performance boundary clock, or ePRTC in specific operating modes. Additional Microchip technologies are also included, including a rubidium atomic clock, FPGA, Ethernet switch, synthesizer, and cleaning oscillator.

European Patent Applications Surpass 200,000 for the First Time… South Korea Maintains 5th Place, Led by Batteries and Telecommunications
According to the European Patent Office (EPO)'s 'Technology Dashboard 2025', European patent applications last year reached 201,974, surpassing 200,000 for the first time. Korean companies and inventors filed 14,355 applications, representing a 9.5% increase from the previous year and maintaining 5th place by country. Battery, digital communication, and semiconductor technologies led the growth, with Samsung ranking as the top EPO applicant for the second consecutive year and LG reaching 3rd place. The presence of major domestic cities such as Seoul, Suwon, and Yongin was also confirmed. It was also revealed that Korea's European patent strategy is expanding beyond individual technologies to span the entire industry.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK Telecom announced that it applied an AI-based network operation system for the first time at a large-scale K-pop concert held in the Gwanghwamun area of Seoul on March 21st, managing communication quality throughout the event. Mobile data usage during the three hours before and after the concert reached 12.15TB, approximately doubling compared to the same time slot the previous weekend. SK Telecom monitored traffic using the AI system 'A-One' in five-minute and 50-meter units to respond to potential overload situations, while also operating temporary communication facilities and on-site personnel in parallel. This case is interpreted as confirmation of the practical applicability of AI-based autonomous network operation in an environment where demand from dense events and foreign users increases simultaneously.
