Bluetooth channel sounding—a new protocol stack designed to enable secure and precise distance measurement between two Bluetooth Low Energy (LE) devices—is propelling Bluetooth technology into a new era of location awareness. It offers true distance awareness while enhancing Bluetooth devices’ ranging capabilities.

Bluetooth channel sounding’s use spans from helping locate devices such as phones or tablets to digital security enhancements like geofencing. It can also be used in smart locks, pet trackers, vehicle keyless entry, and access control applications.

Hardware and software solutions are starting to emerge to fulfill the potential of Bluetooth channel sounding and provide sub-meter accuracy for Bluetooth-empowered devices. These solutions include reference boards, development kits, and software stacks.

Below are two design case studies demonstrating the potential of Bluetooth channel sounding technology.

Radio board and antenna hardware

Silicon Labs’ xG24 radio board—designed to work with Pro Kit—aims to help developers create and prototype products using Bluetooth channel sounding for precise distance estimation. Pro Kit includes a BRD4198A EFR32xG24 2.4 GHz +10-dBm radio board, a dipole antenna, and reference designs. It works with either a coprocessor with an external MCU or a wireless system-on-chip (SoC) with an integrated MCU.

Another xG24 Dev Kit features a dual-antenna PCB design and a channel sounding visualizer tool to allow developers to view distance measurements in real time. Single-antenna hardware offered in the Pro Kit has fewer antenna paths and limited multipath information, which makes it more suitable for basic Bluetooth channel sounding applications.

On the other hand, dual-antenna hardware offers higher accuracy, better spatial performance, and enhanced multipath resolution, making it suitable for advanced applications such as key fobs and tags that demand precise distance estimation (Figure 1). Its antenna diversity also bolsters signal quality and robustness.

Software stack

Bluetooth channel sounding technology uses phase-based ranging (PBR), round trip time (RTT), or both to accurately measure the distance between two Bluetooth LE-connected devices. PBR utilizes the principle of phase rotation in RF signals to determine precise distance between two devices. On the other hand, RTT, a communication channel, refers to the duration a signal takes to travel from the initiator to the reflector and back again.

The above solution from Silicon Labs uses both, employing RTT to verify and cross-check the PBR measurements. However, Metirionic, a German supplier of wireless ranging and positioning technologies, offers an alternative to both PBR and RTT by leveraging the channel impulse response (CIR) technique for highly accurate and reliable distance estimation.

Its Bluetooth channel sounding evaluation kit—Metirionic Advanced Ranging Stack (MARS)—is a low-power signal-processing upper-layer software (Figure 2). It can run on Nordic’s nRF54L15 embedded MCU, on an external MCU or processor, or on a host PC to ensure precise, reliable and real-time ranging and location accuracy for industrial, Internet of Things (IoT), real-time location services (RTLS), logistics, and secure access applications.

My multimeters (generic DT-9205A) 9V battery died. So, I tried to replace the 9V battery with a single 18560 rechargeable battery (3.7V). I connected the battery to a small charging/protec board (TP4056), then connected the output of that to a step up converter (MT3608) (to step up the batteries 3.7V into 9V). Finally, i connected the output of the step up converter to the positive and neg of the battery terminals of the multimeter. The Problem: The multimeter doesn't turn on :0 , after some measuring with a simple LED tester, it seems: Battery gives 4Volts Charger/Prot outputs 4Volts Step Up outputs 0Volts Also, when i measure the voltage at the Vin+ and - of the step up i read 0 Volts I tested the circuit (batt+charg/prot+stepup) alone before connecting it to the multimeter and it was functioning normally, giving 9V. Here are some images of the stuff. submitted by /u/Jolly_Ad717 [link] [comments]

We took a family trip with our grandsons to the New York Transit Museum in Brooklyn, NY. Retired subway cars were on display, some of them seemingly not that old while others dated way, way back. Visitors could freely roam in and out. I was in this one car that had been in service in 1903 which meant it predated the advent of electronics. Even the vacuum tube had not yet been invented by then.

I noticed the passenger area’s bare light bulbs and got really close to one (Figure 1). It was rated at 56 watts and 120 volts. A question came to mind as to how did that car use 120-volt light bulbs when the third rail voltage was (and still is) 600 volts DC?

Figure 1 A subway car light bulb up close showing 56-W and 120-V rating.

When we got home, I tried looking up subway car technical data, but when I came to a wiring schematic, I couldn’t read it. The symbols were indecipherable to me. Only then did it dawn on me that five such bulbs connected in series would be operable from 120 x 5 = 600 volts. If any one of the five were to burn out, all five would go dark, but then maintenance would change all five and discard four good bulbs with the one blown out bulb. It sounded wasteful, but it would have been a practical approach.

Is that the actual truth? I don’t know, and there was nobody on hand to ask, even if I had been quick enough of wit to inquire. Also, I just wasn’t smart enough on site to see if the total number of bulbs in the car was a multiple of five. Maybe one day, I can do that.

Another point about those subway bulbs is that they had left-handed threads on their bases, while household bulbs use right-handed threads. This was to discourage light bulb thefts. Stolen bulbs would not fit into light bulb sockets in households, only into the sockets of subway cars.

Quantum computers are among today’s most exciting emerging technologies, but their design, testing, and manufacturing require unparalleled care to avoid damaging their components. Semiconductors are sensitive, so they require production environments with minimal contamination risks. Cleanrooms are the industry-standard solution, but even these facilities must reach higher standards for quantum computer development.

While a cleanroom overhaul is inherently expensive and disruptive, these costs may be minimal compared to the potential of quantum technology. A quantum chip from Google was recently able to complete a calculation that would take a classic supercomputer roughly 10 septillion years in just five minutes.

This enormous processing upgrade is thanks to quantum computers’ use of qubits instead of bits. Whereas a bit represents either one or zero, a qubit can be both simultaneously—a seemingly small distinction with a dramatic impact on computing speed and power. However, the superconductors and other components necessary to enable this process are highly sensitive to external disturbances.

Many cutting-edge quantum innovations rely on nanotechnology to achieve the desired performance. Nanomaterials have superior thermal stability and electrical conductivity, making them ideal for high-power applications like quantum computing. They also let electronics engineers fit more components in a confined space to uphold Moore’s law.

As helpful as such technologies are, working with them creates an issue in conventional settings. Given their size, nanomaterials are easily contaminateable and breakable. The intensity of quantum operations exacerbates this sensitivity. Even slight deviations in temperatures, light, and air quality could jeopardize the performance of this highly sophisticated and expensive equipment.

A look inside the quantum cleanroom

Quantum cleanrooms are the solution. Engineers must design and build tomorrow’s cutting-edge devices in equally cutting-edge production facilities. Even a conventional cleanroom may be too prone to contamination and environmental variability to support quantum computer development.

The most common cleanroom ratings today are ISO 7 and 8, which allow concentrations of 352,000 and 3.52 million 0.5-micron particles per cubic meter, respectively. These standards also don’t consider any particulate matter below 0.5 microns. While that’s sufficient for traditional semiconductor engineering, quantum cleanrooms must go further. Ratings of ISO 6 and above that do limit sub-0.5-micron particles are necessary.

Cleanrooms for quantum development also need different sanitation methods. Researchers at Berkeley Lab recently found that gentler component cleaning resulted in an 87% increase in induction, making parts more resistant to electrical noise. The method in question used lower temperatures, vacuums, and suspended components to minimize environmental hazards.

Even lighting and ambient temperatures require attention in the quantum cleanroom. Many of these components are photosensitive to blue wavelengths, particularly, so overhead lights should lean more toward the warm end of the spectrum. Quantum circuits also tend to be temperature-sensitive, so these cleanrooms must use gentle refrigeration techniques to keep the area cold.

Quantum electronics engineers must get used to cleanrooms

As quantum technology advances, electronics design engineers may need to adapt to it. The professionals designing, testing, and producing tomorrow’s most advanced electronics must learn to work with their unique production requirements. Getting used to the quantum cleanroom is a crucial step in getting ready for this next generation of computing.
