2. Bluetooth - Wikipedia

   en.wikipedia.org/wiki/Bluetooth

   A personal computer that does not have embedded Bluetooth can use a Bluetooth adapter that enables the PC to communicate with Bluetooth devices. While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB " dongle ".

3. List of Bluetooth profiles - Wikipedia

   It enables identification of the manufacturer, product id, product version, and the version of the Device ID specification being met. It is useful in allowing a PC to identify a connecting device and download appropriate drivers. It enables similar applications to those the Plug-and-play specification allows.

4. SBC (codec) - Wikipedia

   en.wikipedia.org/wiki/SBC_(codec)

   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]

5. List of Bluetooth protocols - Wikipedia

   en.wikipedia.org/wiki/List_of_Bluetooth_protocols

   The Bluetooth protocol stack is split in two parts: a "controller stack" containing the timing critical radio interface, and a "host stack" dealing with high level data. The controller stack is generally implemented in a low cost silicon device containing the Bluetooth radio and a microprocessor.

6. LDAC (codec) - Wikipedia

   en.wikipedia.org/wiki/LDAC_(codec)

   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.

7. Bluetooth Low Energy - Wikipedia

   en.wikipedia.org/wiki/Bluetooth_Low_Energy

   Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries.

8. IEEE 802.15 - Wikipedia

   en.wikipedia.org/wiki/IEEE_802.15

   The IEEE 802.15 Task Group 4d was chartered to define an amendment to the 802.15.4-2006 standard. The amendment defines a new PHY and such changes to the MAC as are necessary to support a new frequency allocation (950 MHz -956 MHz) in Japan while coexisting with passive tag systems in the band.

9. Bluetooth stack - Wikipedia

   en.wikipedia.org/wiki/Bluetooth_stack

   A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack.. Bluetooth stacks can be roughly divided into two distinct categories: . General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers.
