Big upgrade: The difference between Bluetooth 5.0 and 5.2

 The Bluetooth headset is expected to finish in 2 minutes. 

 

1. The transmission speed is different.

Compared with the Bluetooth 5.0 version, Bluetooth 5.2 can bring twice the data transmission speed, and the data transmission capacity can be increased by 800%. In other words, using Bluetooth 5.2 can transmit and receive more data at a faster speed.

 

2. The working distance is different.

Compared with the Bluetooth 5.0 version, Bluetooth 5.2 has a bandwidth (transmission speed) increased from 1Mbps to 2Mbps, and the transmission distance is increased to 4 times stronger, that is, the theoretical effective working distance is 300 meters, and low power consumption mode is also possible.

 

3. The broadcasted data packets are different.

Compared with the Bluetooth 5.0 version, Bluetooth 5.2 can broadcast 255 Byte data packets instead of 31 Bytes, thereby reducing the transmission efficiency loss caused by interference in the 2.4GHz frequency band.

 

The main advantages of Bluetooth 5.2 include: a more efficient connection through lower power consumption and time-limited data communication. Low energy consumption (LE) synchronization channels allow audio transmission to interact between multiple devices, and LE power control can optimize the transmitter power. These characteristics enable Bluetooth devices to coexist better with other wireless devices in the 2.4GHz frequency range.

 

 

 


Bluetooth Knowledge:


From Wikipedia, the free encyclopedia

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz, and building personal area networks (PANs).[4] It was originally conceived as a wireless alternative to RS-232 data cables. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 meters (30 feet).

Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks.[5] A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device.[6] A network of patents apply to the technology, which are licensed to individual qualifying devices. As of 2009, Bluetooth integrated circuit chips ship approximately 920 million units annually.[7]
