Digital Enhancement Unveils First Commercial RPU (Radio Processing Unit), Marking a Leap in Wireless Performance for Consumer Electronics

LAS VEGAS, Jan. 7, 2025 /PRNewswire/ -- Digital Enhancement (Hangzhou) Co., Ltd (hereafter referred to as "Digital Enhancement") is set to unveil the world's first commercial-grade Radio Processing Unit (RPU) designed for Wi-Fi wireless access at the CES International Consumer Electronics Show in Las Vegas, USA.

This groundbreaking RPU and solution leverage Digital Enhancement's innovative "Digital RF" technology, delivering a 10x performance boost in Wi-Fi high-speed coverage. The innovation promises to redefine the wireless connectivity experience for consumer electronics, paving the way for a new era of seamless and high-performance wireless connections.

The RPU employs state-of-the-art closed-loop training and real-time calibration architecture. Equipped with a high-performance hybrid analog-to-digital-to-analog predistortion algorithm, it significantly improves RF system performance through cutting-edge digital compensation technology.

The RPU introduces an innovative "plug-in" enhancement model, decoupling RF performance from the baseband system-on-chip (SoC) for the first time. This independent design allows consumer electronics manufacturers to flexibly create new integrations based on product requirements, enabling a seamless plug-and-play experience.

Built-in RPU acts as a "turbocharged engine" for RF systems, providing stronger signals and elevated user experiences. With RPU integration, Wi-Fi routers deliver broader high-speed coverage, while bridge devices achieve higher transmission speeds and longer ranges. Additionally, RPU enhances power amplifier (PA) output without increasing harmful emissions and wasting power as heat. This reduces reliance on costly and heavy directional antennas by lowering antenna gain requirements. For industrial Wi-Fi applications, the RPU ensures robust anti-aging performance, maintaining stable power output without speed degradation.

Dr. Ziming Wang, Founder and CEO of Digital Enhancement, stated: "Wireless RF performance determines signal coverage and speed, directly impacting the user's connectivity experience. Digital Enhancement is the world's first innovator to miniaturize and simplify complex digital compensation algorithms used in high-power 5G macro base stations, bringing green digital RF technology to consumer electronics.

Our unique plug-in solution offers industry a new avenue for product differentiation. Whether a product aims for a tenfold performance improvement, focuses on RF system efficiency and thermal management, or strives for out-of-band suppression to enable multi-device coexistence, this approach provides unparalleled flexibility. The RPU-equipped modular solutions we've introduced for Wi-Fi 6/7 wireless access include mass-production support for 500mW and 1W in the 5GHz-6GHz band at MCS11 rates, as well as lab data achieving 3W output when paired with nonlinear FEMs.

Throughout our journey, we've been driven by a deep understanding of end-user application scenarios and a commitment to innovating technologies that meet their most fundamental connectivity needs."

As AI+ continues to advance, wireless RF performance has become the critical gateway through which cloud computing power and services are delivered to users via consumer electronics. Traditional methods of "stacking resources" to improve performance often introduce side effects such as increased complexity, management challenges, handoff issues, and interference. It's akin to connecting multiple carts together and expecting the efficiency of a train.

Digital Enhancement has introduced a game-changing innovation with its RPU, leveraging digital RF technology to simplify complexity. This disruptive, original solution marks a leap forward in enhancing consumer electronics performance, aligning with the industry's pursuit of green energy efficiency and sustainable development.

Moving forward, Digital Enhancement plans to expand its global collaborations with Wi-Fi router manufacturers, industrial Wi-Fi module developers, and 5G CPE device providers, continuing to drive green digital RF solutions that empower high-performance wireless connectivity in consumer electronics.
