SBC, or low-complexity subband codec, is an audio subband codec specified by the Bluetooth Special Interest Group (SIG) for the Advanced Audio Distribution Profile (A2DP). [1] SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers. It can also be used on the Internet. [2]
Low Latency High-Definition Audio Codec (LHDC) is an audio codec technology developed by Savitech.LHDC allows high-resolution audio streaming over Bluetooth.It is a high-quality Bluetooth codec based on the A2DP Bluetooth protocol and allows a bit-rate of up to 900 kbit/s compared to SBC's bit rate of 345 kbit/s .
Recent models generally use Bluetooth 4.0 or even Bluetooth 5, and wireless speakers generally have a range of 10 meters. [4] Bluetooth devices use a radio communication frequency such that the devices do not have to be in a visual line of sight with each other. Some speakers may benefit from the NFC system to facilitate pairing with the source ...
The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10.

High fidelity (often shortened to Hi-Fi or HiFi) is the high-quality reproduction of sound. [1] It is popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion , and a flat (neutral, uncolored) frequency response within the human hearing range .
Bluetooth mesh networking – Specification providing a mesh networking variant to Bluetooth Low Energy (BLE) with an increased number of nodes and standardized application layer (Models). Li-Fi (light fidelity) – Wireless communication technology similar to the Wi-Fi standard, but using visible-light communication for increased bandwidth.
