Bluetooth 7 Speeds Set to Quadruple in 2027, Especially for Audio

Bluetooth data speeds will soon quadruple under an upcoming update to the wireless standard. The trade association that oversees the technology, the Bluetooth Special Interest Group, unveiled this flagship upgrade as Bluetooth High Data Throughput within the Bluetooth Core 7.0 standard.

The update pushes maximum bit rates for Bluetooth Low Energy to 7.5 megabits per second. That performance quadruples the throughput of existing LE 2M technology. Devices built for the new standard are scheduled to reach store shelves starting in 2027.

This speed increase will benefit everyday electronics like phones, tablets, laptops, and smart speakers. The rollout will begin with premium wireless audio products such as earbuds, before expanding to other uses. Those later uses could include spatial computing, local artificial intelligence data exchanges, health wearables, and smart home tools.

Øyvind Strøm, executive vice president of the short-range business unit at Nordic Semiconductor, said the technology opens the door to more sophisticated and data-heavy applications. He noted that smartwatches could sync hours of sensor training data in seconds, smart glasses could offload data for richer artificial intelligence features, and smart home products could finish software updates with almost no visible downtime.

The performance boost comes from a redesigned physical layer, which is the foundational part of the protocol that handles sending and receiving data signals. New modulation schemes allow this physical layer to handle information more efficiently and move more data at once. These technical upgrades also improve overall energy efficiency to preserve battery life across various devices. Smart locks, wireless earbuds, and other accessories will run longer before needing a battery replacement or a recharge.

While the first compatible flagship devices are expected to appear in early 2027, an exact release date has not been announced. Because major protocol changes take time to adopt, manufacturers may take years to transition their product lineups to the new standard.

Summary

The Bluetooth Core 7.0 standard multiplies wireless data speeds by four, reaching 7.5 megabits per second to improve performance and battery life. Although the rollout begins with premium wireless audio in 2027, the underlying physical layer improvements lay the groundwork for data-heavy uses like artificial intelligence tasks, health tracking, and smart home automation.
