Breakthrough Hardware and Software Boosts Bluetooth Device Ranging Accuracy and Security

AUSTIN, Texas, Sept. 3, 2024 /PRNewswire/ — Silicon Labs (NASDAQ: SLAB), a leader in secure, intelligent wireless technology for a more connected world, today announced its support for Bluetooth® Channel Sounding technology on the xG24 platform.

Bluetooth® Channel Sounding is a new protocol stack designed to enable secure and precise distance measurement between two Bluetooth Low Energy (LE) connected devices. By offering true distance awareness, Bluetooth® Channel Sounding enhances the accuracy and security of Bluetooth device-ranging capabilities.

“In a world where location awareness is critical, Bluetooth® Channel Sounding revolutionizes proximity and location capabilities, propelling Bluetooth technology into a new era,” said Ross Sabolcik, Senior Vice President of the Industrial and Commercial Business Unit at Silicon Labs. “With a legacy of empowering developers with the full potential of Bluetooth technology, Silicon Labs’ latest hardware and software create an accelerated path to groundbreaking Bluetooth products equipped with Bluetooth® Channel Sounding.”

Bluetooth Channel Sounding Enhances Accuracy and Security for Distance Awareness

By helping to estimate the distance between two devices, Bluetooth Received Signal Strength Indicator (RSSI) opened the door for a new wave of applications. From solutions to help locate devices like phones or tablets to digital security enhancements like geofencing, Bluetooth technology has enhanced the convenience and simplicity of everyday tasks. The challenge, however, is that Bluetooth RSSI has relied on estimations to determine location. RSSI is also susceptible to issues like multipath and obstruction which can significantly reduce accuracy. Bluetooth® Channel Sounding addresses this by improving the accuracy to sub-meter and enhancing the security of Bluetooth device ranging capabilities.

Bluetooth® Channel Sounding uses Phased-Based Ranging (PBR) to deliver precise distance measurements between two devices and a secondary ranging method called Round Trip Time (RTT). The independent distance measurements from RTT can then be used to verify and cross-check the PBR measurements. This cross-verification process helps detect anomalies to ensure applications are secure, which is critical when developing access control solutions for hospitals and industrial buildings that must grant or deny access based on proximity.

With PBR and RTT, Bluetooth® Channel Sounding can be used in home and life applications like smart locks, locating consumer electronic devices, and pet trackers, as well as industrial and commercial applications like geofencing, vehicle keyless entry, and access control – all while delivering accurate, secure, and dependable Bluetooth ranging services. With advanced distance estimation techniques, Bluetooth® Channel Sounding can also be used to triangulate the position of commercial infrastructure like wireless access points or luminaires to either meet regulatory requirements or save human labor and costs.

Additionally, Bluetooth® Channel Sounding offers a more convenient and flexible ranging solution for applications that already use Bluetooth LE. In such cases, it can be implemented without the need for extra hardware and design space.

Silicon Labs New xG24 and Antenna Hardware Solutions Support Channel Sounding

Silicon Labs’ new xG24 Radio Board and Pro Kit, available to order now, provides a fast and efficient way to create and prototype products using Bluetooth® Channel Sounding for precise distance estimation.

Faith: The Spark Born by the Yudu Riverside

Published

By

BEIJING, Oct. 18, 2026 /PRNewswire/ — An interview from China.org.cn with Wang Xiaohui and David Ferguson on the Long March:

David Ferguson:

This is the Yudu River. One dusk in October, 1934, more than 86,000 soldiers of the Red Army crossed this river and embarked on the Long March, a two-year saga that has left its mark in history.

Yet, lingering here by the river, I am struck by a simple question: If you have faith in a bright future, and reality seems to thwart you at every turn, where do you find the moral strength to keep believing?

Wang Xiaohui:

At dusk on Oct. 17, 1934, an army of more than 86,000 troops gathered along the banks of the Yudu River. Over 800 boats of all sizes floated on the water, bound together with planks collected from villagers’ home gates, timber beams, and even coffin boards reserved for elderly locals. The people of Yudu built this pontoon bridge, determined to help the army led by the Communist Party of China (CPC) cross the river.

At that time, no one knew that the great expedition embarked upon by the banks of the Yudu River would go on to transform China and exert far-reaching influence across the world.

China in the 1920s and 1930s was plagued by chaos and despair.

The Kuomintang (KMT), the ruling party back then, was not capable of unifying the nation, leaving warlords locked in endless fighting. In 1931, Japanese invaders launched an assault on northeastern China, beginning their invasion. Crushed under domestic turbulence and foreign aggression, countless civilians were displaced, with many even starving to death on the streets; in certain regions, severe drought resulted in zero harvests, yet the farmers were forced to pay land taxes assessed for more than a decade into the future.

Amid this turmoil, the only glimmer of hope for the Chinese nation was kindled by the revolution ignited by the Communist Party of China.

The CPC, dedicated to winning liberation for the people and national independence, built contingents of workers’ and peasants’ Red Army troops and revolutionary base areas across the countryside. Impoverished farmers were granted land ownership, as well as unprecedented political dignity. On Nov. 7, 1931, the Chinese Soviet Republic was officially proclaimed in Ruijin, then a small village in southeastern China’s Jiangxi Province, establishing a Soviet system under which workers, peasants and soldiers elected representatives to run regional affairs and make policies.

The communist ideal of a fair society free from exploitation and equality for all blazed like a spark in the darkness; it kindled hopes among impoverished Chinese and became the wellspring of faith that enabled the Red Army — a force made up of poor workers and peasants — to overcome all hardships in the days to come.

Yet, bright as the spark was, it burned thin and fragile at times. Could this flame still endure when the ideals it carried were repeatedly battered by harsh reality?

In September 1933, flocks of warplanes clouded the skies over the Red Army’s revolutionary base areas. By then, Japanese invaders were steadily advancing towards North China, but Chiang Kai-shek’s KMT turned a blind eye to the looming national crisis. They mobilized over a million troops and more than 200 aircraft to launch a massive offensive at the Red Army’s base areas. Over the previous three years, Chiang Kai-shek had mounted four major military “encirclement” campaigns aimed at exterminating the Red Army, but all ended in failure. He was desperate for a pivotal victory to restore his prestige and to wipe out the CPC and the Red Army.

At the time, the commander of the Red Army abandoned mobile warfare tactics pioneered by Mao Zedong and other commanders, opting instead for rigid positional warfare involving conventional head-on clashes. But the reality was, some Red Army units didn’t even possess a single light machine gun; how could they confront the heavily-armed KMT army head-on?

Zhong Ming, a Red Army medic, could never erase the memories of gravely wounded soldiers being carried to his aid station. He remembered how a soldier whose chest was blown open begged his comrades to end his life. At the frontline, a whole battalion of Red Army soldiers religiously followed orders to defend crude earth-and-wood bunkers, but under the constant barrage of KMT artillery and airstrikes, every soldier in the battalion laid down their lives; not a single man survived.

What’s more heart-wrenching is that no matter how fearlessly the Red Army fought, the steep imbalance in military strength, paired with erroneous military command led to irreversible losses. By October 1934, the KMT’s iron-clad encirclement closed menacingly around Ruijin.

Faced with this dead-end, what decision would you make?

This stood as the most agonizing decision for the Red Army. The biggest challenge lay not in sacrificing one’s life for an ideal, but in finding a way to keep the revolutionary cause alive.

To stay meant defeat — the Red Army had no room to maneuver within the Central Revolutionary Base Area. To break through the encirclement, however slim the odds, offered a fighting chance. Preserving the Red Army as a living force mattered much more than clinging to isolated strongholds. Where the spark survives, the path ahead remains lit.

The air already turned chilly in October. Units of the Central Red Army assembled in Yudu to prepare for a strategic shift. The plan was kept strictly classified; none of the soldiers knew they were evacuating the base areas, only sensing an unusual vibe.

At dusk on Oct. 17, crowds lined up at the Yudu riverbank. Tens of thousands of villagers flocked from every corner to see the Red Army off. They walked alongside the marching columns, slipping food like eggs and glutinous rice balls into the soldiers’ pockets, praying for their swift homecoming.

The main force of the Central Red Army set off. Within days, they left behind revolutionary base areas where they had survived, grown and taken root. No one anticipated that the journey they embarked on would become the Long March, a trek spanning over 10 provinces. Still less could anyone imagine that this journey would ultimately pave the way for a brand-new China.

Looking back on this chapter of history, many claim that the Red Army only set out on this expedition because the enemies left them no other choice. To a degree, yes, the Long March was indeed a forced strategic shift, yet this fact does nothing to diminish its greatness and glory.

The ordinary Red Army soldiers had no idea how far they would march, or where they were heading. But they clung firmly to their founding mission: to deliver liberation for the people and independence to the nation. This unswerving conviction kept them from disintegrating through countless perils, sustaining them as they marched into the unknown with resolve.

David Ferguson:

I now realize that faith and ideals untested by harsh reality may have no true substance.

Since its founding, the Communist Party of China has always upheld the realization of communism as its fundamental goal. Despite devastating losses and extreme adversity, the Red Army continued to press forward resolutely and never faltered. Its inner strength came from an unshakable belief in the cause, an unwavering commitment to the founding aspiration, and a profound sense of mission. The Red Army was never fleeing pursuers in search of safety; it was marching forward to a future in which it had a steadfast belief.

Wang Xiaohui:

The Long March went on for two years. The Red Army trekked 25,000 li across some of China’s harshest terrain, but they kept their heads high, seeking hope amid despair and marching towards light through unending darkness. The lofty ideals and sense of mission they upheld have also become the torch that guides generations of CPC members in the following centennial, tempering them into steel as they press forward unswervingly toward national rejuvenation.

That spark lit along the Yudu River has never dimmed since.
