Whether it’s your headphones, your smartwatch, your mouse, or your keyboard, you probably use Bluetooth to wirelessly connect your devices each and every day. So many devices use the wireless communications standard that you might end up pairing or repairing them once every couple of days. Pairing Bluetooth devices can be a hassle, which is why Google created Fast Pair, a feature that greatly simplifies the Bluetooth pairing process. Fast Pair currently works with accessories like headphones, smartwatches, tracker tags, and mice, but Google is preparing to expand support to keyboards.

Google Fast Pair Service, or just Fast Pair for short, was introduced back in 2017 and was originally designed to simplify connecting audio accessories like speakers, headphones, and car kits with devices running Android. It’s implemented in the Google Play Services app on Android phones, tablets, smartwatches, and TVs, which means it’s available on any Android device that ships with Google apps preinstalled. Since March of 2023, it’s also been available in the Chrome OS operating system running on Chromebooks.

Phones with Bluetooth hearing aid compatibility (updated June 2024)

1. Červen 2024 v 08:50

More and more people have some form of hearing impairment in this increasingly loud day and age. You may remember hearing aids as bulky devices sitting behind your ears that are barely good enough to make people hear again, but this is far from the truth today. Most hearing aids support some form of audio streaming. Still, you need a compatible Android phone for most of them.

Startup Sends Bluetooth Into Low Earth Orbit

13. Květen 2024 v 21:54


A recent Bluetooth connection between a device on Earth and a satellite in orbit signals a potential new space race—this time, for global location-tracking networks.

Seattle-based startup Hubble Network announced today that it had a letter of understanding with San Francisco-based startup Life360 to develop a global, satellite-based Internet of Things (IoT) tracking system. The announcement follows on the heels of a 29 April announcement from Hubble Network that it had established the first Bluetooth connection between a device on Earth and a satellite. The pair of announcements sets the stage for an IoT tracking system that aims to rival Apple’s AirTags, Samsung’s Galaxy SmartTag2, and the Cube GPS Tracker.

Bluetooth, the wireless technology that connects home speakers and earbuds to phones, typically traverses meters, not hundreds of kilometers (520 km, in the case of Hubble Network’s two orbiting satellites). The trick to extending the tech’s range, Hubble Network says, lies in the startup’s patented, high-sensitivity signal detection system on a LEO satellite.

“We believe this is comparable to when GPS was first made available for public use.” —Alex Haro, Hubble Network

The caveat, however, is that the connection is device-to-satellite only. The satellite can’t ping devices back on Earth to say “signal received,” for example. This is because location-tracking tags operate on tiny energy budgets—often powered by button-sized batteries and running on a single charge for months or even years at a stretch. Tags are also able to perform only minimal signal processing. That means that tracking devices cannot include the sensitive phased-array antennas and digital beamforming needed to tease out a vanishingly tiny Bluetooth signal racing through the stratosphere.

“There is a massive enterprise and industrial market for ‘send only’ applications,” says Alex Haro, CEO of Hubble Network. “Once deployed, these sensors and devices don’t need Internet connectivity except to send out their location and telemetry data, such as temperature, humidity, shock, and moisture. Hubble enables sensors and asset trackers to be deployed globally in a very battery- and cost-efficient manner.”

Other applications for the company’s technologies, Haro says, include asset tracking, environmental monitoring, container and pallet tracking, predictive maintenance, smart agriculture applications, fleet management, smart buildings, and electrical grid monitoring.

“To give you a sense of how much better Hubble Network is compared to existing satellite providers like Globalstar,” Haro says, “We are 50 times cheaper and have 20 times longer battery life. For example, we can build a Tile device that is locatable anywhere in the world without any cellular reception and lasts for years on a single coin cell battery. This will be a game-changer in the AirTag market for consumers.”

The Hubble Network system—and presumably the enhanced Life360 Tags that should follow today’s announcement—use a lower energy iteration of the familiar Bluetooth wireless protocol.

Like its more famous cousin, Bluetooth Low-Energy (BLE) uses the 2.4 gigahertz band—a globally unlicensed spectrum band that many Wi-Fi routers, microwave ovens, baby monitors, wireless microphones, and other consumer devices also use.

Haro says BLE offered the most compelling, supposedly “short-range” wireless standard for Hubble Network’s purposes. By contrast, he says, the long-range, wide-area network LoRaWAN operates on a communications band, 900 megahertz, that some countries and regions regulate differently from others—making a potentially global standard around it that much more difficult to establish and maintain. Plus, he says, 2.4 GHz antennas can be roughly one-third the size of a standard LoRaWAN antenna, which makes a difference when launching material into space, when every gram matters.

Haro says that Hubble Network’s technology does require changing the sending device’s software in order to communicate with a BLE receiver satellite in orbit. And it doesn’t require any hardware modifications of the device, save one—adding a standard BLE antenna. “This is the first time that a Bluetooth chip can send data from the ground to a satellite in orbit,” Haro says. “We require the Hubble software stack loaded onto the chip to make this possible, but no physical modifications are needed. Off-the-shelf BLE chips are now capable of communicating directly with LEO satellites.”

“We believe this is comparable to when GPS was first made available for public use,” Haro adds. “It was a groundbreaking moment in technology history that significantly impacted everyday users in ways previously unavailable.”

What remains, of course, is the next hardest part: Launching all of the satellites needed to create a globally available tracking network. As to whether other companies or countries will be developing their own competitor technologies, now that Bluetooth has been revealed to have long-range communication capabilities, Haro did not speculate beyond what he envisions for his own company’s LEO ambitions.

“We currently have our first two satellites in orbit as of 4 March,” Haro says. “We plan to continue launching more satellites, aiming to have 32 in orbit by early 2026. Our pilot customers are already updating and testing their devices on our network, and we will continue to scale our constellation over the next 3 to 5 years.”

  • The Google Pixel 6, Pixel 6 Pro, and Pixel 6a don’t seem to support Bluetooth LE Audio, the standard that defines audio streaming over Bluetooth Low Energy.
  • Bluetooth LE Audio enables lower latency, higher quality audio streaming via the LC3 codec, as compared to the standard SBC codec used by Bluetooth Classic Audio.

Although Bluetooth LE Audio was announced at the beginning of 2020, there still aren’t that many audio products on the market that support it. In 2024, though, we’re finally seeing many audio products come on the market with LE Audio support either out of the box or soon in a future update. However, to actually take advantage of LE Audio’s numerous benefits and new features, you need to own a mobile device or PC that supports the standard. Unfortunately, if you own a Google Pixel 6, Pixel 6 Pro, or Pixel 6a, then you may need to upgrade your phone entirely to use Bluetooth LE Audio.

When you connect your phone to a pair of wireless earbuds, the source device (your phone) and the sink device (your wireless earbuds) establish a connection via their Bluetooth radios. During the pairing process, the devices negotiate to find out what profiles they both support. These profiles define how the two devices exchange data. The profile typically used for streaming audio from the source to the sink device over Bluetooth is called the Advanced Audio Distribution Profile (A2DP). The exact codec that’s used to store the audio data that’s transmitted between the two devices depends on what codecs both devices support, but at a minimum, both devices must support the low-complexity subband codec (SBC).

Qualcomm’s Newest Chip Brings AI to Wi-Fi

27. Únor 2024 v 14:00


Wireless spectrum is always at a premium—if you’ve ever tried to connect to Wi-Fi in a crowded airport or stadium, you know the pain that comes from crowded spectrum use. That’s why the industry continues to tinker with ways to get the most out of available spectrum. The latest example: Qualcomm’s FastConnect 7900 chip, which the company unveiled Monday at Mobile World Congress in Barcelona.

Qualcomm touts the FastConnect 7900 as a provider of “AI-enhanced” Wi-Fi 7, which the company views as an opportunity to create more reliable wireless connections. The chip will also better integrate the disparate technologies of Wi-Fi, Bluetooth, and ultrawideband for consumer applications. In addition, the chip can support two connections to the same device over the same spectrum band.

The FastConnect 7900 comes as the wireless industry renews its focus on reliability with Wi-Fi 7, the wireless tech standard’s latest generation. The emphasis comes in addition improving throughput and decreasing latency, something to which every Wi-Fi generation contributes.

(Wi-Fi is a range of wireless networking protocols based on the IEEE 802.11 set of standards. The IEEE is IEEE Spectrum‘s parent organization.)

AI-Enhanced Wi-Fi

“[Wi-Fi’s] a bit like the wild, wild West,” says Javier del Prado, vice president for mobile connectivity at Qualcomm. “It’s all sorts of devices out there, congestion, devices that come in and go off, access points that do this, access points that do that—it’s very difficult to guarantee service.” Del Prado says that AI is the “perfect tool” to change that.

Key to the FastConnect 7900’s capabilities is the chip’s ability to detect what applications are in use by the device. Different applications use Wi-Fi differently: For example, streaming a video may require more data throughput, while a voice chat needs to prioritize low latency. After the chip has determined what applications are in use, it can optimize power and latency on a case-by-case basis.

Using AI to manage wireless spectrum connections isn’t a new problem or solution, but Qualcomm’s chip benefits from running everything on-device. “It has to run on the device to be effective,” says del Prado. “We need to make decisions at the microsecond level.”

Put another way, using the Wi-Fi connection itself to transmit the information about how to adjust the Wi-Fi connection would defeat the purpose of AI management in the first place—by the time the chip receives the information, it’d be way out of date.

Also important: The chip doesn’t suck power—in fact, it saves power overall. “These are fairly simple models,” says del Prado. “It’s not a 5 billion parameter AI. It’s a much smaller model. The key performance indicators are the speed and the accuracy.”

Del Prado says that the chip’s power consumption is negligible. In fact, because of its ability to optimize power depending on what applications are running, the chip saves its device up to 30 percent in power consumption.

Wi-Fi and Bluetooth and Ultrawideband, All in One

Outside of cellular, Wi-Fi is the most common way our phones connect with the world. But it’s not the only tech—Bluetooth is used for things like wireless earbuds, and ultrawideband (UWB) also sees some use for applications like item tracking (think Apple’s AirPods) and locking and unlocking cars remotely. All three technologies rely heavily on proximity and distance ranging to maintain wireless connections.

“There are all these use cases that use proximity and that use different technologies,” says del Prado. “Different technologies bring different benefits. There’s not always a single technology that fits all use cases. But that creates complexity.”

Qualcomm’s FastConnect 7900, del Prado says, will hide that complexity. “We make it technology-agnostic for the consumer.”

Sharing Spectrum Bands

One final trick the FastConnect 7900 offers is an ability to host two Wi-Fi connections on the same band of spectrum. Here, the chip is building on previous FastConnect generations. “We already introduced what we call ‘hybrid-simultaneous’—this is the capability of doing multiple channels simultaneously on the 5- and 6-gigahertz bands,” says del Prado.

New to the 7900 is audio over Wi-Fi, says del Prado. Qualcomm is calling it “XPAN,” and it’s a separate channel for audio only in those 5-GHz and 6-GHz bands.

This matters because those spectrum bands can deliver a much higher audio quality to the device compared to, say, Bluetooth, which operates in the 2.4-GHz band. By carving out a separate channel just for audio, says del Prado, the 7900 chip can provide that much better audio quality without it succumbing to the strain that typically emerges when multiple connections demand the same wireless signal. “That’s something that cannot be done with Bluetooth today, because it’s bandwidth-limited,” says del Prado.

Qualcomm is already sampling the FastConnect 7900 to its customers—that is, manufacturers of phones and similar devices. Del Prado estimates that the first products with the chip will hit the market in the second half of the year. “When the new round of premium Android phones hits the market later this year, those should support this functionality.”
