Shipments

Annual Device Shipments

Total number of devices shipped will follow a steady incline

Analysts anticipate seeing long-term forecasts returning to strong growth post pandemic. By 2028, 7.5 billion Bluetooth-enabled devices are forecasted to ship annually, representing an eight percent compound annual growth rate (CAGR) over the next five years.

Total Shipments

Shipments by Radio

Bluetooth® technology supports multiple radio options, allowing developers to build products that meet the unique connectivity needs of their customers.

Today, all key platform devices, including smartphones, tablets, laptops, and TVs, are Bluetooth Dual-Mode devices, including both Bluetooth Classic and Bluetooth LE radios. Because of this, most Bluetooth devices shipped over the last five years have been and will continue to be Bluetooth Dual-Mode devices. Furthermore, with the introduction of LE Audio, many audio devices, such as earbuds, are also shifting to Bluetooth Dual-Mode operation.

Due to the ongoing strong growth of connected consumer electronics devices, combined with the growing adoption of LE Audio, peripherals will continue to drive the growth of single-mode Bluetooth LE device shipments. Annual shipments of single-mode Bluetooth® LE devices will almost match those of dual-mode annual device shipments over the next five years.

1.8 BILLION

Bluetooth® LE single-mode devices are forecasted to ship in 2024

Peripherals drive single-mode Bluetooth® LE device growth

Driven by continued strong growth in peripheral devices, Bluetooth® LE single-mode device shipments are forecasted to more than double over the next five years. In addition, when you consider both single-mode LE and dual-mode Classic + LE devices, 97 percent of all Bluetooth devices are expected to include Bluetooth LE by 2028.

100%

of key new smartphones, tablets, and laptops support dual mode (Bluetooth® Classic + Bluetooth LE)

All key platform devices support Bluetooth® Classic and Bluetooth LE

Developers can count on Bluetooth® Classic and Bluetooth LE to be in all key platform devices. With Bluetooth LE and Bluetooth Classic in nearly 100 percent of new phones, tablets, and laptops, the number of dual-mode platform devices supported by Bluetooth technology is reaching complete market saturation.

3.5 BILLION

Bluetooth® peripheral devices are expected to ship in 2024, growing to 5.5 billion in 2028

Peripherals will continue to drive the growth of Bluetooth® device shipments

Since nearly all smartphones, tablets, and PCs support Bluetooth® LE, the growth rate of Bluetooth technology in peripheral devices will continue to outpace platform device growth, growing at a CAGR of 12% over the next five years.

Upcoming Enhancements

The Bluetooth SIG member community continues to expand the capabilities of Bluetooth® technology - powering innovation, creating new markets, and redefining what is possible in wireless communication. The hard work and collaboration between our member companies drive continuous innovation. Typically, there are more than 50 active specification projects in process, and here is some of the work underway to enhance Bluetooth technology.

Channel Sounding

Adding to the growing set of device positioning capabilities of Bluetooth® wireless technology - which currently includes advertising (for presence), RSSI (for course ranging), and direction finding (for high-accuracy direction) - a specification development project is currently underway to enable secure, fine ranging between two Bluetooth enabled devices. This feature is expected to support the creation of locating systems that can provide even higher levels of accuracy.

High Data Throughput

The LE 2M PHY was introduced to address a number of market opportunities, including enhancing data transfer performance for the growing number of IoT devices consumers were connecting to their smartphones. Today, an increasing number of these connected devices are looking for even greater performance, as well as support for streaming larger media, and could benefit from an even higher data rate Bluetooth® LE PHY. The High Data Throughput project was established to address that growing market need and intends to support data rates up to 8 Mbps.

Bluetooth LE in Higher Frequency Bands

A specification development project is currently underway to define the operation of Bluetooth® LE in additional unlicensed mid-band spectrums, including the 6 GHz frequency band. The new spectrum expansion project will help ensure that Bluetooth performance enhancements, including higher data throughput, lower latency, and greater positioning accuracy, can continue well into the future.
