Bluetooth 6.0: A New Standard in Wireless Communication

Many still believe that Bluetooth is a technology for short-range, low-speed data transmission. However, modern versions of Bluetooth have advanced significantly. The new Bluetooth 6.0 standard promises a revolution in wireless connections, allowing data to be transmitted to multiple devices simultaneously and creating scalable networks.

How Did Bluetooth Become a Key Communication Standard?

Unlike Wi-Fi, Bluetooth was initially developed as a wireless data interface for peripheral devices. The technology's development began in the 1980s at Ericsson. However, the first official Bluetooth specification was released only in 1999.

In 1998, the Bluetooth Special Interest Group (SIG) consortium was formed, including giants like Ericsson, Intel, Nokia, IBM, and Toshiba.

Thanks to its open standard and lack of licensing fees, Bluetooth technology quickly captured the market. By 1999, the first mobile phone with Bluetooth support, the Ericsson T36, was released.

How Does Bluetooth 6.0 Differ from Wi-Fi?

Bluetooth operates in the 2.4 GHz range, like Wi-Fi, but its principles of operation and application differ. Unlike Wi-Fi, which is designed for large data transfers, Bluetooth was developed for energy-efficient connections of peripheral devices.

Bluetooth uses 79 narrow channels each 1 MHz wide, whereas Wi-Fi has fewer but wider channels. This reduces the likelihood of interference and improves connection stability.

The first version of Bluetooth had a very low speed of just 721 kbps over a distance of up to 10 meters. However, the technology has significantly evolved over time.

The Evolution of Bluetooth: From the First Version to 6.0

  • Bluetooth 1.0 (1999) – the basic version of the standard, allowing devices to connect over short distances.
  • Bluetooth 2.0 (2004) – increased data transfer speed and reduced power consumption.
  • Bluetooth 3.0 (2009) – high-speed mode using Wi-Fi for fast data transfer.
  • Bluetooth 4.0 (2010) – introduced Low Energy (BLE) mode, allowing devices to operate on batteries for years.
  • Bluetooth 5.0 (2016) – increased range (up to 240 m) and data transfer speed (up to 2 Mbps).
  • Bluetooth 6.0 (2024) – the main innovation: Channel Sounding technology for ultra-precise positioning.

Each generation of Bluetooth brought improvements in speed, connection stability, and energy efficiency. However, version 6.0 offers truly groundbreaking capabilities.

Bluetooth 6.0: Channel Sounding Technology

One of the key innovations of Bluetooth 6.0 is Channel Sounding technology, which allows determining the location of a device with an accuracy of up to 1 cm. This significantly surpasses the previous capabilities of Bluetooth 5.0, where accuracy was 50-100 cm.

Channel Sounding makes Bluetooth 6.0 ideal for use in logistics, warehousing processes, the smart home industry, and indoor navigation.

It is worth noting that a similar precise positioning technology has long been used in Apple AirTag and the Find My system, but there a different technology is used – Ultra Wideband (UWB). Bluetooth 6.0 offers an alternative to UWB, operating in a more accessible frequency range.

Why is Bluetooth 6.0 Important for the Market?

Despite the presence of UWB, the new Bluetooth 6.0 standard is in demand because it:

  • Does not require additional chips to operate.
