The Growing Threats Presented by RF Devices

Wireless, RF-enabled IoT devices such as drones, cell phones, satellites, Bluetooth, and Wi-Fi routers are already ubiquitous, and their presence is growing. These IoT devices are vulnerable to being hacked and manipulated. The hackers can use these devices for clandestine activities to aid data theft or other criminal activities. A powerful tool called RF hacking can enable bad actors to deploy sophisticated threats like rogue access points and devices to jam or spoof critical communications and GPS. These RF hacking tools are easy to assemble with consumer parts and software from the internet and can be deployed in drones, handhelds, or both.

There are several perimeter safety and security approaches used to detect intruders. Smart cameras and radar are among the most widely adopted strategies, and under ideal operating conditions they provide sufficient levels of information. In practice, however, their performance is degraded by conditions such as rain, snow, dust, obstacles, and variable terrain. What’s more, these solutions have a high false alarm (false positive) rate. They also do not provide information about malicious RF attacks.

Passive RF sensors are an alternative to smart cameras and radar. Passive RF sensors provide sensor data that is highly reliable and more actionable. RF safety and security is also less intrusive and easier to deploy. Because of computing complexities, however, RF sensing solutions have been cost prohibitive and used only by governments.

Challenge: Promising Startup with a Demanding Workload

R2 is an Israeli startup with deep expertise in security and signal processing. Employing a patented algorithm, R2’s solution transforms a signal into bits for analysis that delivers actionable data to operators. R2 recently signed a commercial agreement to protect a large number of critical infrastructure sites with their novel approach to RF safety and security. R2’s solution uses low-power passive RF sensor arrays to observe the RF signal of devices inside the perimeter.

The sophisticated algorithm combines the solution’s matrix multiplication workload with deep learning and machine learning models. This workload makes it a challenge to find a scalable compute platform with efficient performance while meeting the size weight, power, cost, and cooling (SWaPC2) requirements for the solution. 

Solution: Business and Technology Acceleration Through Intel® Ignite

Intel saw the deep value R2 could offer businesses for safety and security applications. From a field of standout startups, Intel selected R2 for participation in the Intel Ignite accelerator program. This partnership helped R2 move rapidly through multiple stages of business and solution development.

When R2 joined Intel Ignite, the R2 solution was dependent on a specialized GPU architecture to handle their complex signal processing workload. R2 wasn’t exposed to the scalable, COTS, lower-cost, open ecosystem options enabled by Intel® technologies and products. Intel Ignite provided R2 with the right support, including hardware platforms for trial products.

“Migration to Intel® architecture from specialized GPU architecture was easy and quick for R2. What’s more, transitioning between Intel platforms for testing to address SWaPC2 needs took only a few hours,” says Dr. Yiftach Richter, CEO of R2. The speed of this transition helped reduce R2’s development time. Before long, R2 was able to build an optimized platform that delivered their customers’ performance needs at a dramatically lower overall SWaPC2 than a specialized GPU-based solution.

Bringing Down the Cost and Complexity of RF Safety and Security

Using COTS and open-ecosystem-based products and technology rather than specialized architectures, R2 was able to bring down the cost and complexity of their RF safety and security solutions. In R2’s testing, 11th Gen Intel® Core™ processors were highly performant and more cost-effective overall than the specialized, GPU-centric infrastructure they had previously employed.

Most importantly for R2’s product development, Intel offers a range of solutions that meet a variety of SWaPC2 requirements. This flexibility allowed them to optimize their offering for maximum efficiency across the different parts of their solution—from low-power sensors at the edge to the high-performance cloud instances.
