CSR: When developing the QardioArm what were the top five things you wanted to achieve? 

Qardio: We wanted QardioArm to be easy to use, comfortable, clinically validated with safe data transfer and to have a long battery life. All of this has been possible with the use of CSR’s Bluetooth Smart technology.

The ability to control the device pairing experience directly from the smartphone application has ensured the device is incredibly simple to use from the very first time. A simple tap between the QardioArm and the phone and the user is ready to start using the product.

We wanted the device to be comfortable and the combination of the wireless technology with the compact design created a blood pressure device that is simple and convenient to have around at all times for daily measurements.

The low power consumption offered by CSR’s Bluetooth Smart technology means users don’t have to continually charge their device. And the small form factor of the chip has helped us deliver a compact design.

Users want to feel confident that data is accurate and safely stored. The encryption mechanism embedded in Bluetooth Smart technology has been crucial in helping us achieve that.

CSR: Why did you choose to work with CSR?

Qardio: We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points.

CSR: How do you think the personal medical market will evolve in the next five years?

Qardio: The market has seen an explosion of self-quantified applications in the last few years. Now with medical devices coming to the market with a consumer-focused design we will start collecting an unprecedented amount of clinical data that will help improve patient care. We will see companies creating predictive algorithms giving people the ability to truly achieve preventive care, lowering the unsustainable current trend of increasing healthcare costs.

CSRmesh™ – A key component to the Internet of Things and the world’s most exciting technology, says The Times Raconteur special report

CSR was featured this week in the ‘Internet of Things’ special report, published by the prestigious Raconteur and distributed in The Times. It contains an interesting series of articles looking at how everything is getting plugged into the internet and how through machine-to-machine communications, it is making a sizeable impact on how we live. It’s worth a read, but definitely check out pages 8-9, where CSRmesh is not only mentioned as one of the ten applications making the IoT the world’s most exciting technology, but also because it features a great infographic exploring the segmentation of the IoT market.

“Devices in close proximity relay messages to each other to form a local network. For example, Cambridge Silicon Radio’s CSRmesh uses the Bluetooth radio signal found on every smartphone. The consumer connects to a Bluetooth-smart IoT device, which then sends that message to affiliated devices in a giant chain or mesh. Bluetooth can stretch 30 metres, but via a mesh, a message can leapfrog devices to cover much larger distances.”

Sky News reports on CSRmesh™ and Bluetooth® powering the Internet of Things

CSR recently met with the SWIPE tech team from Sky News to talk about how Bluetooth® is changing the way we interact with the world. Reporting from the Future is Smart exhibition organised by the Bluetooth Special Interest Group, the report focuses on CSRmesh™ having a key role in the future of wireless technology:

“Bluetooth isn’t just about mobile headsets anymore, a new generation of wireless technology is ready to transform homes, exercise, medicine and even farming. It’s because Bluetooth 4.0 lets devices talk to each other using very little power, like these light bulbs from Cambridge-based company CSR. One app can control tens of thousands of [light bulbs] at once, right down to changing the colour of each individual bulb. And the technology has even greater potential.”

Motor Trend highlights aptX® and the importance of compression in audio quality

CSR recently talked with Motor Trend’s Frank Markus ahead of Telematics Detroit 2014. The popular U.S. based publication posted a round-up of the highlights from the show including a section on aptX®, CSR’s audio coding technology which streams CD-like audio quality over a Bluetooth® connection:

“Did you realize that most in-car receivers currently capable of streaming music from your brought-in device are doing so at a lower, MP3-or-worse level of quality? That’s because they use an SBC codec. This low-complexity Sub-Band Coding or (SBC) was specified by the Bluetooth Special Interest Group. British-based CSR plc has developed a different compression coding called aptX that delivers greatly improved frequency response for near-lossless stereo audio quality. PC and Mac computers and Android devices all use aptX today, so the last step is to get the receivers to recognize and employ it for better car-audio sound quality, and that will happen soon.”

The Expanding Role of Bluetooth® in High Quality Audio Applications

I attended Bluetooth World 2014 and was privileged to be invited to speak as part of a panel discussion on the continually expanding role of Bluetooth® in the audio market, what’s driven its growth and the positive impact Bluetooth Smart is expected to have on the sector.Capture

The backdrop to the panel session was a recently published report from Research and Markets which found that the wireless audio market is set to grow 24% through to 2018 and will then be worth $13.75bn. So the panel session was keen to explore what has driven market growth to date and what will continue to ensure the market expands.

Bluetooth for audio first started gaining traction in mono headsets in the early 2000s and was primarily used by busy professionals or safety-conscious drivers to make phone calls. After initial steady growth, the market largely plateaued a couple of years ago until two factors came together to propel a second wave of rapid growth. The first was a dramatic improvement in the audio quality delivered over Bluetooth, and CSR’s aptX® CODEC had a huge part to play there, and the second being the widespread consumer adoption of media-rich smartphones and tablets.

This combination matched perfectly with the consumer’s increasingly mobile lifestyles and resonated with their growing familiarity and use of wireless devices.  As a result, consumers readily embraced listening to wirelessly streamed music either for personal enjoyment, or shared with friends.

Portable Bluetooth speakers were the first music audio devices to really grab the mainstream consumer’s attention, and having gained an appreciation of the capabilities and benefits that Bluetooth audio had to offer, this naturally led to rapid market volume growth. This acceptance and confidence in Bluetooth audio technology then saw the investment in other devices such as headphones and sound bars increase too.

Looking ahead, Bluetooth Smart has the potential to simplify the user experience even further. For example, in Home Entertainment Audio, the technology has the capability to detect who has walked into a room and can automatically queue up a song which relates to previous choices they have made at a similar time of the day. It simplifies the consumer experience, so users don’t have to navigate through menus themselves, making it a much more personable experience.

The wireless audio market continues to grow, and with Bluetooth Smart offering a more tailored experience to consumers there’s no saturation point in sight. But for the true potential of wireless audio to be realised, there needs to be powerful and flexible platforms at the heart of the development. Find out more about how our audio platforms can help deliver captivating audio experiences.

If you weren’t able to attend Bluetooth World, catch up on the panel session – The Expanding Role of Bluetooth in Audio

What do you think will be the future for Bluetooth in audio? It would be great to get your thoughts and any questions you may have on the topic.

CSR accelerates prototyping of Automotive SoC platforms

The design complexity of CSR’s next-generation of platform solutions for Automotive Infotainment creates new challenges that current pre-silicon development methodologies struggle to support.

Together with the Cadence R&D team, CSR’s Technology Development & Implementation (TDI) group took on these challenges and developed a novel solution which enables faster software development during the early phase of hardware design. CSR Israel’s Moshe Berkovich, a senior engineer in the TDI group, presented this new and innovative solution for fast prototyping at the 51st Design Automation Conference (DAC 2014) held recently in San Francisco.

Moshe’s presentation, entitled “Using Palladium/VSP Hybrid to Accelerate SW Development”, was part of the Cadence® Theater at DAC program, a lively place to learn – directly from EDA users – how to apply Cadence tools to real-world problems.

The new concept offers a hybrid solution which blends the real hardware implementation with the virtual/abstract modules of the compute-intensive CPU. Together, CSR and Cadence have demonstrated a new approach to accelerated simulation environments which is claimed to be 200 times faster than existing solutions.

Precise Location – Myth or Reality?

Hamid Ahmadi

Is greater accuracy of wireless location devices important and can it be achieved?

What started life as a casual navigation tool, is now being squeezed for more and more performance, according to speakers at the Cambridge Wireless (CW) conference on 5th June hosted by CSR. Wireless industry experts focused in on the issues of location accuracy, looked at the formulation of accuracy, the current methods that are being used, and whether these can be improved and integrated.

Recent studies in both the UK and the United states have shown that while the majority of calls to emergency services are being made from smartphones, as opposed to landlines, the main challenge is the ability to locate the caller. The moment a call is made, GPS navigation is switched off to save battery life, while at the same time, social media, location based apps and texting claim to provide high levels of location accuracy.

Hamid Ahmadi, VP/Chief Innovation Officer, CSR said, “Central to the Position Eco-system is accuracy. This Cambridge Wireless event has allowed us to consider its relevance to various use cases, the importance and difficulties in assessing it. The various presentations covered GNSS and in-doors positioning, in both general and technical manners, overall providing very insightful information.”

Dr Ramsey Faragher, Senior Research Associate, University of Cambridge, speaking at the event explored what happens ‘Behind the Little Blue Dot’. “We have all become accustomed to the reliability of the little blue dot on our smartphone maps and the fusion of satellite, cellular and Wi-Fi positioning systems mean that it is rare to find ourselves stuck without a position fix. But what started life as a casual navigation tool for vehicular navigation, is now being squeezed for more and more performance.” Ramsay pointed to possibility that smartphone technology will soon have the accuracy to direct you to your seat at the football. “That level of accuracy requires an appreciation of what happens behind the little blue dot.”

CSR at Telematics Detroit 2014 – Bluetooth Smart opening doors

It was clear from last year’s Telematics events that there is a strong appetite among tier 1s and OEMs for integrating more Bluetooth® Smart connectivity applications.

Later in 2014, the first volumes of Tyre Pressure Monitoring Systems (TPMS) based on CSR’s Bluetooth Smart technology will be hitting the aftermarket space. It’s just one example of a multitude of opportunities to exploit Bluetooth Smart in-vehicle. From keyless entry systems replacing proprietary lock and unlock technologies to smartphone apps saving drivers preferred settings and displaying diagnostic information, controlling your vehicle directly from your smartphone as opposed to via the car’s telematics control unit is certainly an attractive proposition for consumers and businesses alike. Imagine car rental businesses such as Hertz and Avis providing apps that configure the rental car according to your preferences when you enter the vehicle.

While certainly convenient, this is not the primary reason for car makers to choose Bluetooth Smart. It comes down to economics. Bluetooth Smart reduces the need for as much wiring and cabling in the car, and wire replacement applications can substantially reduce the weight (up to several kilos) and complexity of establishing communication networks in the car. Ultimately it offers the opportunity to consolidate systems. TPMS and keyless systems using Bluetooth Smart can communicate directly to the dual-mode head unit device, thereby eliminating the need for dedicated TPMS and keyless receivers.

In addition, since Bluetooth Smart is a globally licensed ISM band technology, using it reduces costs associated with geographical skews that the varying frequencies of TPMS and keyless systems currently produce.

Dual-mode Bluetooth Smart chips have been shipping into the automotive market since 2011 and are already embedded in head units, ready to communicate with the Bluetooth Smart chips in steering wheel switches, TPMS sensors, key fobs, remote controls etc. We expect the global Bluetooth Smart attach rate to significantly increase over the coming years. With the CSR1010™ auto, as well as the CSRC9300™ audio-centric Bluetooth Smart/Wi-Fi® combo chip (now in mass production) and the CSR8350™, CSR is primed to meet suppliers’ Bluetooth Smart requirements.

Our recently launched CSRmesh™ solution, which is a protocol that enables ad-hoc over multiple Bluetooth Smart nodes, can also be wielded to significantly enhance many non-safety critical functions in the car. For example, a high rise parking lot with sensors throughout would be able to tell an incoming driver where exactly in the lot free spaces are, using CSRmesh to communicate with the sensors throughout the lot to locate that free space.

CSR will be demoing its Bluetooth Smart solutions at Telematics Detroit 2014 – feel free to visit CSR at booth 77.
