Bluetooth Market & SIG Membership Growth 2020

Bluetooth continues to be the global wireless standard powering IoT devices within the home and commercial sectors, with the Bluetooth Special Interest Group (SIG) continuing to drive innovation of the technology year on year. This latest market work shows membership continuing to grow with 15 different ‘working groups’ working on 80 Bluetooth specifications including new ones and enhancements to existing ones. Membership of the group continues to grow as the number of Bluetooth devices continues to increase with no signs of slowing down.

The market continues to shift away from Bluetooth Classic devices to Bluetooth LE and dual-mode. With 7.5 Billion Bluetooth LE devices expected to ship over the next 4 years. By which time 100% of phones, tablets and laptops are expected to ship with dual-mode support.

This latest market update highlights the technologies progression from its initial implementation of a simple wireless replacement for audio products before expanding into data transfer and how location services and large scale device network solutions.

Bluetooth Technology Trends 2020

LE Audio

Announced at the start of 2020 LE Audio, is another innovation extending the capabilities of Bluetooth audio. LE Audio introduces support for hearing aids, Multi-Stream Audio and Broadcast Audio using Bluetooth Low Energy promising reduced power demands compared with Bluetooth Classic.

Multi-Stream enables the “transmission of multiple independent synchronized audio streams”, introducing a new standard for developing products like true wireless earbuds. Currently, products like Pixel Buds or Airpods rely on the device playing audio to stream to one of the two earbuds, which must then perform complex syncing behaviour with its pair. Multi-Stream Audio can be broadcast from the source device such as a smartphone to one or more audio sink devices. Making solutions easier to develop and improving support for stereo imaging experience you may have seen Apple’s Spatial Audio feature announced during the WWDC keynote or makes the use of voice assistant services more seamless, and makes switching between multiple audio source devices smoother

Multi-Stream goes hand in hand with Broadcast, which introduces the ability to stream one or more audio streams to an unlimited number of devices. This audio Audio Sharing solution enables anything from sharing a song with a friend to choose to tap into the audio from that airport television or assistive services for individuals with a disability. 

In order to support these new use cases, the new Low Complexity Communications Codec (LC3) has been introduced. Promising high quality at low data rates, also giving developers the flexibility to make decisions on the tradeoffs between audio quality and power consumption.

Mesh Networking

Bluetooth mesh adoption for Smart Building, Smart Industry, Smart Cities, and Smart Home continues to increase. Mesh technology is well suited to control, monitoring and automation. Devices are connected in many to many relationships to allow access and control from any point in the network by relaying messages between nodes to their destination. Removing the need for potentially costly centralised infrastructure, and the potential for single points of failure. 

Mesh networks are secure making use of encryption and authentication at both the application and network layers making use of out of band (OOB) authentication techniques and AES-CCM encryption to secure all messages. Mesh systems can be used as stand-alone networks without additional infrastructure for increased security. 

Bluetooth mesh offers a platform on which a range of solutions can be implemented. Commercial lighting continues to be a leading use case with 300 pages of the 1,000 Mesh Model specification devoted to it. The high level of detail in the specification makes it easier than ever to develop applications which work with a large number of devices without having to worry about proprietary technology. The Van Gogh Museum in Amsterdam is combining smart lighting with sensors to save energy while maintaining visitor experience and minimise art work to light exposure.

Technology Conclusions

  • Bluetooth continues to be a technology of choice for developing solutions to meet the ever-expanding need for wireless connectivity.
  • As well as being solution-oriented with Smart lighting driving adoption of Bluetooth Mesh and hearing aids for LE Audio. Building an in-depth specification around these devices will provide a clear framework for technology to be adapted to meet other use cases.
  • Watching how premium audio brands like Bowers and Wilkins will respond to LE Audio, specifically the new Low Complexity Communications Codec (LC3) will be interesting. It remains to be seen if it will challenge the Qualcomm alternatives. A requirement for LE Audio to gain ground within the current Headphones market.
