LDAC is an alternative to Bluetooth SIG's SBC codec. Its main competitors are Huawei's L2HC, Qualcomm's aptX-HD/aptX Adaptive and the HWA Union/Savitech's LHDC. [1]LDAC utilizes a type of lossy compression [2] [3] by employing a hybrid coding scheme based on the modified discrete cosine transform [4] and Huffman coding [5] to provide more efficient data compression.
Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi IEEE 802.11 , while others depend on Bluetooth to transmit audio data to the receiving speaker.
Bluetooth LE Audio also allows one-to-many and many-to-one transmission, allowing multiple receivers from one source or one receiver for multiple sources, known as Auracast. [122] [123] It uses a new LC3 codec. BLE Audio will also add support for hearing aids. [124] On 12 July 2022, the Bluetooth SIG announced the completion of Bluetooth LE ...
Many car audio consumer electronics manufacturers like Kenwood, JVC, Sony, Pioneer and Alpine build car audio receivers that house Bluetooth modules all supporting various HFP versions. Bluetooth car kits allow users with Bluetooth-equipped cell phones to make use of some of the phone's features, such as making calls, while the phone itself can ...
The main tasks for the SIG are to publish the Bluetooth specifications, protect the Bluetooth trademarks and evangelize Bluetooth wireless technology. In 2016, the SIG introduced a new visual and creative identity to support Bluetooth technology as the catalyst for the Internet of Things (IoT).

Using this approach, it is possible to join together numerous piconets into a large scatternet, and to expand the physical size of the network beyond Bluetooth's limited range. Currently there are very few actual implementations of scatternets due to limitations of Bluetooth and the MAC address protocol. However, there is a growing body of ...
