Cable fault locators play a key role in these networks by accurately detecting and locating faults or breaks within cables, ensuring timely repairs and reducing downtime. For instance, in October 2025, the International Energy Agency, a France-based intergovernmental organization, reported that global electricity consumption increased by 4.3% in 2024 and is projected to grow by approximately 4% annually through 2027. Additionally, in February 2025, PricewaterhouseCoopers, a UK-based professional services firm, stated that global telecom industry revenues from fixed and mobile services rose by 4.3% in 2023, reaching US$1.14 trillion in 2024. Therefore, the increasing demand for reliable electrical and telecommunication networks is fueling the expansion of the cable fault locator market.

Major companies in the Bluetooth Low Energy (BLE) devices market are prioritizing the development of innovative system-on-chip (SoC) solutions to deliver enhanced functionality for end users. A SoC is an integrated circuit that consolidates multiple electronic components and functions into a single chip, incorporating all essential elements required for Bluetooth communication. For instance, in May 2025, Renesas Electronics Corporation, a Japan-based semiconductor manufacturer, introduced a Bluetooth Low Energy SoC equipped with an Arm Cortex-M0+ microcontroller, along with an integrated radio transceiver, memory, and peripherals. The Renesas DA14533 BLE SoC offers ultra-low power consumption, featuring an active transmission current of about 3.1 mA, a reception current of 2.5 mA, and a hibernation mode current of approximately 500 nA, making it well-suited for battery-powered automotive applications. Its single crystal oscillator architecture, combined with an integrated DC-DC buck converter, minimizes the need for external components and helps reduce overall system costs.
