As the de-facto standard for audio streaming and short range IoT connectivity, Bluetooth device shipments are expected to approach 5 billion units annually by 2022 and surpass 6 billion units annually by 2025, according to the latest forecasts from ABI Research. On the back of this huge addressable market, the Bluetooth standard continues to evolve to meet ever-more challenging goals on battery life and performance. The Bluetooth Core Specification Version 5.3 was unveiled at the end of June 2021 and the Bluetooth SIG confirmed the release on July 13, 2021.
With Bluetooth 5.3 comes new features including Enhanced Periodic Advertising and LE Connection Subrating, all designed to improve protocol efficiency in terms of power and latency. Link robustness is also enhanced with the LE Channel Classification signaling, as is wireless security with improvements in the HCI Encryption Key Size Control. The enhancements in the standard by the Bluetooth SIG coupled with the ultra-low power architecture of the RivieraWaves Bluetooth IP platform gives chip designers a winning edge in the highly competitive wireless consumer market.
"We congratulate the Bluetooth SIG on the release of the Bluetooth 5.3 specification, and we are delighted to offer this latest version to our customers to enable rapid time-to-market. Having powered more than 520 million Bluetooth devices in 2020 alone, our RivieraWaves Bluetooth IP is an integral part of the Bluetooth ecosystem. We look forward to working with our Bluetooth 5.3 customers for the introduction of new products leveraging the exciting features of this latest standard," comments Ange Aznar, Vice President and General Manager of the Wireless IoT Business Unit at CEVA.
CEVA’s RivieraWaves Bluetooth IP platforms provide comprehensive solutions for both Bluetooth low energy and Bluetooth dual mode connectivity. Each platform consists of a hardware baseband controller, plus a feature-rich and comprehensive software protocol stack. A flexible radio interface allows the platforms to be deployed with either RivieraWaves RF or various partners’ RF IP, enabling optimal selection of foundry and process node.
All the latest features of Bluetooth are supported, including Isochronous Channels for LE Audio, Direction Finding (AoA/AoD), Randomized Advertising Channel Indexing, Periodic Advertising Sync Transfer, GATT Caching and other enhancements.
